I have seen both styles and I believe it is just a matter of personal choice and style.

Those who know me personally, are aware that my background is Mathematical as I did Degree in Mathematics Honours in the year 1993-95. During my early days with COBOL and Pascal, I never dealt with Unicode or played with bytes. Even when I moved to C, I was still no where near it. Those with Degree in Computer Science always stay ahead in the understandings of these low level key aspects of programming.

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.

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.

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.

Luckily I saw a tweet from him talking about his blog for the weekly challenge.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
Continue Reading
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.

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.

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.

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.

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.

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.

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).

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.

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.

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.

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.

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? The club members get the first glimpse of upcoming challenges. How can anyone join the club? Just drop us a line with your intention to perlweeklychallenge@yahoo.com. I always try to give the club members full weekend i.e. Saturday and Sunday to play with the upcoming challenges before others get their hand the following Monday morning.

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.

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

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.

First find out the latest challenge folder, more likely the highest numbered folder is the latest challenge folder e.g. challenge-002. If you are an existing member, you would probably find a folder by your name. For example, if your name is “Joe Blog” then there would be a folder called “joe-blog”. Under your named folder, you would find a file README.

For the first time, since I started participating the weekly challenges, I thought of doing one-liner. With handy CPAN modules, it was pretty straight forward in Perl.

PERL Task #1: kth Permutation Sequence The CPAN module Algorithm::Combinatorics is becoming very popular and favourite among Perl Hackers.

The next person followed him was @smokemachine. He has been regular since last week.

I noticed last week, less participation than the previous week. Why? Honestly speaking I have no clue. Could it be the questions were too tricky for the challenge? The week before, I received the feedback that the questions were too easy and simple. So I went for little trickier one this time. It seems that I have to balance it somehow. I am gratefull to all members submitting the solutions as Pull Request.
