Andrew Shitov Weekly Review: Challenge - 268

Raku Solutions Weekly Review Pre-thoughts The first task was to find the magic number that, when added to every item of the first array, converts the array in such a way that all the numbers that you get after the addition are found in the second array of the same length. Sounds messy, but it effectively means that if you sort both arrays, then the difference between their corresponding elements is constant.

Raku Solutions Weekly Review Task 1 In the first task, you have an array of integers @ints and a target number $k. You need to print the indices of those elements, which are equal to the target, but you need to search in the sorted source data. Thoughts What does Raku offer that can be used in this task? First, the sort routine, which you can use as a method or as a stand-alone function:

Andrew Shitov Weekly Review: Challenge - 262

Raku Solutions Weekly Review Task 1 The first task was to find and display the number of either positive or negative integers, whatever is larger. Let us start from the easy part. In Raku, there is a a built-in max function (or method if you want to use an object notation: @array.max). So, the code is: say max($neg, $pos); where $neg and $pos are the numbers of negative and positive data items in the original array.

Lets be friend ...

What is the point of this blog? It has been a long time since I last blog. The main reason behind the blog is put forward my views in response to the questions raised earlier. It did hurt me to read about it. Havind said, I do my best not to upset anyone knowingly. It would have been lot better if it was addressed to me and not public. The mission PWC came into existence to fill the void created by the closure of “Pull Request Challenge” ran by Neil Bowers.

HEADLINE I am back to my routine life but still not there fully. I am going to talk about my Perl and Raku solutions to both tasks to start with. Last week, I only talked about my Perl and Raku solutions to the task Prime Sum. This week also, I skipped Swift contributions like last week, sorry. I would blame my laziness. I am happy with my effort this week. It gives me immense pleasure when I do Raku implementation completely different from Perl.

HEADLINE Although I had finished the “Word Search” task a week before, still I didn’t have time to complete the “Prime Sum” task. After checking out others solution to the “Word Search” task, I was feeling low looking back my own solution. To recover from it, I delayed solving the “Prime Sum” task. At the same time, as a protest, I didn’t do Swift solutions for any of the tasks. After few days when I was feeling a little better, I decided to do at least one task better.

BLOG: The Weekly Challenge #075

HEADLINE The week #075 tasks turned out to be a lot trickier than expected. Generally Task #1 is meant for beginners only but this time it was not the case. It wasn’t my plan when I proposed the task. I thought couple of for-loops and job done. But when I actually started working on the task, I realised it wasn’t as simple as I thought initially. But the good thing is, I got to know about Dynamic Programming (DP).

RECAP - Perl Weekly Challenge - 074

HEADLINES Lets welcome new member Nuno Vieira from Braga, Portugal before we discuss anything. I remember last Monday as soon as I made the weekly challenge public, within minutes literally, I had the first contributions. Guess who? Mark Anderson, one of the member of elite Early Bird Club. Do you also want to join the club? It is very simple, just drop us a line at perlweeklychallenge@yahoo.com. I wanted to be the first contributor as I had solved both the tasks in Perl, Raku and Swift already.

The Weekly Challenge - 075

HEADLINES Well done Team PWC, we did it. It took us 74 weeks to break the record of 2 consecutive weeks of 100+ contributions. Just to remind you it was right at the start, Week #001 and Week #002. In between we did manage to cross the magical number but never once crossed 3 in a row. 1) Week #001: 142 2) Week #002: 109 3) Week #030: 115 4) Week #033: 108 5) Week #046: 106 6) Week #072: 109 7) Week #073: 108 8) Week #074: 112 Having done this now, we should now aim to break the record of maximum contributions in a week.

HEADLINE Ever since I started doing Swift, I find myself too busy again with my weekly video sessions on top of all. I need to re-visit my time management chart, may be? Having said that, I get excited by the doing task in a new language. I wanted to do it in Java to refresh my memory. But couldn’t find time for it as I am editing the next week Perl Weekly newsletter also.

Perl Weekly Challenge - 074

HEADLINES The week #072 was full of pleasant surprises, one of them was getting past 100 contributions. The whole Team PWC needs a big round of applause. Having set the target so high, the following week #073 was under pressure to perform. Honestly speaking, it was me who wanted to get somewhere close to the peak if not beat the previous high. To keep the followers of @PerlWChallenge up to date, I kept sharing the progress during the week.

RECAP - Perl Weekly Challenge - 073

HEADLINES Welcome back Mano Chandar. Although he joined the Team PWC long time ago but he shared his first contributions in Perl this week. I am not sure if you noticed, in the recent weeks, the language list is growing very rapidly. As of today, we have received solutions in 24 languages in addition to Perl and Raku. If you remember, it all started in the week #018 by a respected guest Orestis Zekai when he shared his solutions in Python.

HEADLINE Happy Independence Day to all my fellow Indians This week tasks are once again fun and challenging. Keeping the balance is very difficult, I must admit. but I am trying … For the first time, I have joined the private Early Bird Club and taking the advantage of doing the challenge before the launch. I am not sure, if you noticed, this I shared by solutions before lunch time on day one.

HEADLINES What a week it has been, we crossed the 100 mark once again !!! Congratulations, Team PWC. Last time we crossed the magic number was in the Week #046.

HEADLINES Welcome back Adam Russell after short break. Thanks for sharing not just one but two blogs. I would also like to thank Lance Wicks for the regular live session. Scimon Proctor also wrote two blogs, one for each task. Thanks for your support and encouragement. For some strange reason, I didn’t see any pull request from Dave Jacoby this week. Luckily I saw a tweet from him talking about his blog for the weekly challenge.

BLOG: The Weekly Challenge #072

HEADLINE No Linked List related task this week? I am glad, this week focus was more Array/List related. Technical speaking Array and List aren’t the same in Perl. I must admit until I read the article by brian d foy, I thought they were the same. As the famous saying, you learn something new every day. Both the tasks, this week were not terribly difficult. I noticed many members of Team PWC attempted other languages because they finished the tasks in no time.

Perl Weekly Challenge - 072

HEADLINES Today is the first Monday of the August 2020 and it is time to announce the Champion of the Month. With great pleasure, we announce the Champion of the Month, Walt Mankowski, currently ranked #044 with score of 58. He joined the Team PWC in the Week #013. As of today, he has contributed Perl (29), C (6) and Python (12). Andrew Shitov is on a mission it seems, he has done not one but two weeks Live Raku Reviews.

RECAP - Perl Weekly Challenge - 071

HEADLINES Welcome back Ben Davies after short break. Thanks for sharing Raku solutions. Jaldhar H. Vyas shared the solutions to the Perl Weekly Challenge - 058. It shows the dedication that he has towards the weekly challenge. Thanks Jaldhar for your support and encouragement. I am not sure, if you have read the blog by Dave Jacoby where he mentioned the comment by Walt Mankowski where he encouraged Dave to do the Trim Linked List as a Singly Linked List purely.

BLOG: The Weekly Challenge #071

HEADLINE With another Linked List related task, I am now enjoying it a lot. It also gives me the opportunity to work with Class in Raku. Learning Raku has changed my thinking a big way. The developer inside me is more organised than before. Also doing regular weekly challenge made me think from unit test point of view every time I come up with a solution. In fact, it dictates the design of my solution.

HEADLINES Finally the wait is over, we found volunteer for Raku Reviews. Any guess? Andrew Shitov joined the team of Raku Reviewers. The best part is, he is doing Live Video Reviews, which is even more fun. I watched all his reviews so far, start to end. There are plenty to learn from just watching him review Raku solutions. He has already done for Week #066 and Week #069.

RECAP - Perl Weekly Challenge - 070

HEADLINE Before I talk about my contribution this week, I would like to talk about my encounter with Swift programming language recently. For the first time, I felt confident that I can share my Swift solution to the Character Swapping task of the Perl Weekly Challenge - 070. Why Task #1 only? Well, you guessed it correctly because it is meant for the beginners. With the submission of my first contribution in Guest Language, I now find myself in the Guest List as you must have seen in RECAPS every week.

Perl Weekly Challenge - 070

HEADLINES Colin Crain has been helping with Perl reviews since Week #065. I would like to thank him for all the hard work. I liked the new layout he came up for the last review. It is different from others. I am not sure about others but I always look forward to review every week. We are still looking for helping hands for Raku reviews. Please let us know perlweeklychallenge@yahoo.

RECAP - Perl Weekly Challenge - 069

HEADLINES Welcome back Rage311 after the break. I hope you stay longer this time. Walt Mankowski surprised me this week by sharing solutions in C and Python. Thanks to him, C is the new language introduced to us. I would also like to thank him for taking Python contributions closer to the magic number. Andrew Shitov joined the gang and shared his first C++. Apart from Andrew, we have few others contributors who also contributed in C++, i.

BLOG: The Weekly Challenge #069

HEADLINE The Task #1 of Perl Weekly Challenge - 069 raised a very interesting question i.e. is 1 strobogrammatic number? So far, I got mixed response some says yes and some not. My first thought was Yes, it is but later changed my mind. It is controversial and I don’t want loose the focus on the task itself. Please remember the objective is to have fun and not to get into controversial domain.

Perl Weekly Challenge - 069

HEADLINES With three members joining Team PWC, we now have 173 members. I welcome all of them with open arms. I would like to mention one member explicitly Myoungjin Jeon, why? He is someone who did Perl long time ago and currently a Chef by profession. What impressed me the most about him is that he never let his love for Perl die. I hope he finds the weekly challenge interesting to keep him going.

RECAP - Perl Weekly Challenge - 068

HEADLINES Two of the three members who joined the Team PWC last week, shared solutions to the “Perl Weekly Challenge - 068”. When I requested them for a brief introduction, most of them came back with Perl background. But then Myoungjin Jeon surprised me with solutions in Raku as well. I came across one of his blog where he mentioned about his work on creating combinations in Perl in the year 2013.

BLOG: The Weekly Challenge #068

HEADLINE The Week #068 is my 23rd week in a row participating the weekly challenge. For the first time, I created a package to deal with the “Reorder List” task. It really helped me in thinking straight when dealing with linked list. With the help my favourite CPAN module Moo, creating class is like piece of cake as shown below. package Node; use Moo; has v => (is => 'rw'); has c => (is => 'rw'); sub show_link { my ($self) = @_; my $head = $self; my @v = (); while ($head->c) { push @v, $head->v; $head = $head->c; } push @v, $head->v; return sprintf("%s", join ' -> ', @v); } I will talk more in detail later down below.

Raku Solutions Weekly Review Task #2: Ordered Lineup This is derived in part from my blog post made in answer to the Week 58 of the Perl Weekly Challenge organized by Mohammad S. Anwar as well as answers made by others to the same challenge. The challenge reads as follows: Write a script to arrange people in a lineup according to how many taller people are in front of each person in line.

HEADLINES Today is the first Monday of the July 2020 and you guessed it correctly. It is time to announce the Champion of the Month. With great pleasure, we announce the Champion of last month, Mark Anderson, currently ranked #027 with score of 122. He joined the Team PWC in the Week #018. As of today, he has contributed Perl (19) and Raku (42). After a long gap, we have Perl and Raku reviews together in one week.

RECAP - Perl Weekly Challenge - 067

HEADLINES Andrew Shitov joined the Team PWC in the Week #065. Last week he shared link to a page dedicated to his recent and past solutions to the weekly challenge. I found it extremely useful to the rest of us. Therefore decided to have it exclusive section in the weekly RECAP blog. Please do checkout his work. Welcome back Chenyf. After a long break, we received his contributions in Raku.

BLOG: The Weekly Challenge #067

HEADLINE This week both tasks had one thing in common i.e. pairing two or more list. In the past, I have taken the help from CPAN module Algorithm::Combinatorics for such tasks. However this time, I wanted to get my hand dirty and came up with the following: # generate all possible combinations my @combinations = (''); foreach my $members (@data) { @combinations = map { my $member = $_; map $member.

BLOG: The Weekly Challenge #066

HEADLINE The much awaited event, **Conference in the Cloud” took most of my free time. Having said that I still managed to do Live Coding YouTube videosfor Divide Integers and Power Integers. I really enjoyed both tasks, specially Power Integers. It didn’t take long to solve both tasks. I was able to get it done by midweek. But for YouTube video, I had to wait until the conference was over. Thanks to the Chief Editor of Perl Weekly newletter editorial note, I now have 67 subscribers to my YouTube Channel.

Perl Weekly Challenge - 067

HEADLINES The highlight of last week was mostly the much awaited event “Conference in the Cloud”. I must admit, I enjoyed every bit. It was nice to see so many familiar names from Team PWC in the audience. Among many talks, I was really happy to watch Damian Conway live for the first time. Colin Crain final joined the team of reviewers and submitted first Perl Review. Please do share your comments and suggestions.

RECAP - Perl Weekly Challenge - 066

HEADLINES Welcome back Walt Mankowski and thanks for sharing your contributions. Also thanks for sharing Python solutions. Thanks Andrew Shitov solving past challenges and blogging about it as well. Python is the most popular language among the Team PWC after Perl and Raku. We now have 10 contributors for Python. 1) Lubos Kolouch: Python (25). 2) User Person: Python (21). 3) Orestis Zekai: Python (16). 4) Burkhard Nickels: Python (8).

Perl Weekly Challenge - 066

HEADLINES The week #065 started on a happy note when I received the contribution by Andrew Shitov. He doesn’t need an introduction, does he? He even blogged about his contribution. On a serious note, I got the sense that most of the Team PWC found the task Palindrome Partition very confusing. I must admit, I also realised when I solved the task myself. I noticed there are more solutions than what I thought initially.

RECAP - Perl Weekly Challenge - 065

HEADLINES I noticed Yet Ebreo catching up past challenges. In the series, he shared Week #062 and Week #063. It is always nice to see members taking interest in solving past challenges. I would like to encourage anyone who joined us recently, please do share your solutions to the past challenges. If you missed the deadline to submit your solutions, please do share anyway. And why not blog about it as well, if you haven’t done so before.

BLOG: The Weekly Challenge #065

HEADLINE Having missed the blog last week, I wanted to make sure it doesn’t happen again. I did catch up the last week blog this week. How did I get time this week around? Well, I delayed Live Coding session for Perl and Raku until Sunday. As of now, I have done 2 videos, one each for both tasks in Perl. I am planning to do one more later in the evening in Raku just for “Digits Sum” task.

BLOG: The Weekly Challenge #064

HEADLINE This weekly blog is coming a week later than normal. Why? Last week I tried Live Coding for the first time. It was scary but enjoyable experience. It took more time than the blog. Having said that I didn’t want to stop blogging about my solutions. So here you go, I am sharing my solutions with you. Just for record, please find below links to the Live Coding videos.

Perl Weekly Challenge - 065

HEADLINES Few days ago, Colin Crain, offered to do Perl review of the past challenges. A big THANK YOU from all of us. Soon we will have the fun of reading reviews. I am still looking for Raku, just a gentle reminder. It would be nice, if both kickstart together. I have been hooked into YouTube video of live coding by Richard Park. It was Richard who first started sharing his YouTube video of live coding.

RECAP - Perl Weekly Challenge - 064

HEADLINES Not sure about others but I have noticed E. Choroba is on a mission to improve his past solutions. Square with 5 distinct digits Invert Tree Find Numbers Nothing comes FREE, the above improvements is keeping E. Choroba too busy to do weekly blog. We are missing them very badly. Hopefully it will start again very soon. Do you remember, Jaldhar H. Vyas? He was missing from the scene for sometime but he is back in action now, back to back 2 weeks.

Perl Weekly Challenge - 064

HEADLINES Two recent tragedies really upset me the most, first the killing of George Floyd and second the killing of pregnant elephant in India. All Life Matters, including Black. I try to keep my political views to select few and avoid sharing on social media. I hope I am not crossing the lines here. The Week #062 was the dullest week ever earlier but thanks to all Team PWC members, it is no longer the least contributions week.

RECAP - Perl Weekly Challenge - 063

HEADLINES Welcome back Jaldhar H. Vyas, we missed you. For the first time ever, I noticed E. Choroba missed a week i.e #062. However, he made it up and shared the solution to the Sort Email Addresses. To my surprise, he even updated his solution to the task Longest Common Substring of Perl Weekly Challenge - 018. It shows his commitment to continuous improvement. Thanks to Richard Park contributions, the solutions in APL (18) is moving up in the rank #003, only behind Python (87) and C++ (22).

Meet The Champion: May 2020

Welcome to the monthly series “Meet The Champion”. Last month we spoke to Luca Ferarri, the winner of April 2020. Today we are talking to Shahed Nooshmand, the winner of May 2020 of “Perl Weekly Challenge”. I hope you are going to enjoy the interview. Mohammad: Tell us about your technical background? Shahed: I have none. I’m a Computer Science student. This is my second semester, and barely — considering you-know-what.

BLOG: The Weekly Challenge #063

HEADLINE After the most difficult week (Week #062), it was very satisfying. I found both the tasks this week (Week #063) fun and challenging. The best part was that I could do both tasks in an hour, which is rare. I liked the “Rotate String” task very much. Thanks to Ryan, we already had test cases handy for the “Last Word” task. I will talk about each in detail down below.

HEADLINE Once again, Neil Bowers, came up with another exciting task for all Team PWC members. Like always, it was fun task. Thanks to Ryan for providng sample data and expected result based on the definition of the task. Half the job done already. The only thing left for the us, is get on with the job. I noticed Raku needed slightly different approach then the Perl. It could be I am doing something very badly.

Perl Weekly Challenge - 062

HEADLINES Happy Idd to all Team PWC members. It was the first Idd celebration when we couldn’t go to the mosque for special prayer. Life is no longer same even after so many weeks on lockdown. It appears we have to start adjusting to the new rules. From next week, I will have new routine to follow as Ramadan is over. Working hours is going to be back to normal.

RECAP - Perl Weekly Challenge - 061

HEADLINES We all know, Perl Weekly Challenge, primarily focus on Perl and Raku. However, in recent weeks, I noticed Team PWC members actively sharing solutions in other guest languages. As of today, we have received solutions in 16 guest languages, Python being the most popular language. There is still scope for more guest languages. If you haven’t tried anything so far then why not give it a try. Newly joined member Sangeet Kar shared his first Python solutions.

HEADLINE At first, I thought Product SubArray is easy task. Therefore I went public categorised as Task #1. My definition of easy task is you just start coding without doing any ground work. However when I started coding, I had to take a pause and do processing in my head befoore coding. So then as per my definition, Product SubArray no longer consider as an easy task. After finishing the task in no time once I understood the flow, it turned out to be clean solution.

Perl Weekly Challenge - 061

HEADLINES I never miss the opportunity of celebration, no matter how small the occassion is. My form of celebration is sharing the achievements with the community in general. If you remember, I wrote a blog when we completed 3 months of weekly challenge. Then again when we completed 6 months. So why no celebration at the end of first anniversary? Certainly it was the biggest moments for all of us associated with Perl Weekly Challenge or rather The Weekly Challenge.

HEADLINES Couple of months ago, on the request of one of the Team PWC member, Wanderdoc, we created Early Bird Club. So what is it all about?

HEADLINE I am not sure about you guys but I found writing blog is very nice feeling. I get nice ideas to clean up the code. This week, I even found a bug that even unit test couldn’t catch. I would rather not share it, quite embarassing. The bug was in my Perl solutions to the “Find Numbers” task. My git commit tree might disclose it, if you really want to know.

Perl Weekly Challenge - 060

HEADLINES Last week, we had the pleasure to interview our Champion of the Perl Weekly Challenge, Luca Ferrari. Please check out the full interview.

I would like to thank Team PWC member Richard Park for introducing the amazing language APL.

Another pleasant surprise from last week was, one of the earliest member of the team, Colin Crain started blogging about his work.

BLOG: The Weekly Challenge #059

HEADLINE This week, I changed the format of my weekly blog slightly. Why? Well, I wanted to keep the Perl and Raku solutions next to each other so that it is easier for reader (me, mostly) to see the difference. It gives me immense pleasure to see the end result when I am done translating Perl solutions into Raku. It looks lot cleaner and precise. The only thing it is behind is performance when I do comparison.

HEADLINE This week, I struggled with both the task, to be honest. Dealing with alpha part of the version was really pain in the neck. Every time, I struggle with any task, I follow the college days course of action i.e. pick a pend and paper. I start dribbling the thought process, it really helps in getting the idea out on the paper. Once the rough draft is ready, it is time to face the unit test trial.

HEADLINE Of the two tasks, my favourite was Shortest Unique Prefix. I must confess I have never done this before. It was fun solving though. I enjoyed it thoroughly. As always, Raku solution looks more elegant, in my hunble opinion. With every passing week, I learn something new in Raku and get to practice what I learnt so far. The weekly challenge is giving me an opportunity to explore the nitty gritty of Raku.

Before I say anything about my contributions, I would like to share my sweet encounter with Raku. Last week while working on the task Flip Binary using Raku, I was struggling to figure out all the binary strings with maximum 1s. I had the results in a Hash where key was the binary string and value was the total count of 1s in it. The idea was to sort the Hash by values first then sort by keys.
