HEADLINES



Before I forget, please let me share the interview with last month champion, Paulo Custodio. It is always great pleasure to know about weekly champion.

As you all know, the season of Advent Calendar is coming soon. Continuing the tradition, I would like to get Advent Calendar 2021 up and running. This year, however, I would like to invite Team PWC to suggest one of their blog for the Advent Calendar. In total, I am looking for 24 blog posts. Ideally one blog per member. For reference, please take a look at past years advent calendars 2020 and 2019.

I am looking forward to another milestone i.e. completing 1000 days of weekly challenge. For this I have designed the T-shirt to celebrate the milestone.


PWC T-Shirt


Ideally I wanted to gift the T-shirt to all the champions of the weekly challenge. But there are couple of things holding me back. First, collecting postal address of all champions and second the financial aspects of procuring T-shirts and delivering. For record, as of today, we have 51 Champions. If possible gift the same to Top 10 guest contributors also. Finding the sponsor is never my cup of tea as you all know. So I am not having high hopes, to be honest.

Last but not least, let us welcome two new members to Team PWC, Kaushik Tunuguntla and Jake.

Last but not least, I would like to thank each and every member for their support and encouragement.



Our solo sponsor Pete Sergeant has been a great support to keep us motivated. We are lucky that he agreed to continue the journey with us in the year 2021. I would like to personally thank Pete and his entire team for their generosity. It would be great if we could add few more to sponsor the prize money so that we could go back and declare weekly champions as we have done in the past. I hope and wish this will become possible in 2021. The amount doesn’t have to be huge. However, it would be nice to show off bunch of supporters. If an organisation comes forward and supports us then that would be the ultimate achievement.

NEW MEMBERS


Jake, Perl enthusiasts.

I’m new to perl and want to learn.

Kaushik Tunuguntla, an experienced Perl Hacker.

I have about 6 years of experience as a software developer and I primarily worked on perl during this time. I came across Gabor’s posts related to perl in the early years googling for perl related stuff and subscribed to his weekly newsletter. He has blogged on all aspects of perl I think. I haven’t followed perl weekly challenge closely till now but it’s better late than never, so let me jump in and join the party.


Please find out How to contribute?, if you have any doubts.

Please try the excellent tool EZPWC created by respected member Saif Ahmed of Team PWC.


GUESTS


Please checkout the guest contributions for the Week #138.

Please find past solutions by respected guests. Please share your creative solutions in other languages.


TASK #1 › JortSort

Submitted by: Mohammad S Anwar

You are given a list of numbers.

Write a script to implement JortSort. It should return true/false depending if the given list of numbers are already sorted.

Example 1:

Input: @n = (1,2,3,4,5)
Output: 1

Since the array is sorted, it prints 1.

Example 2:

Input: @n = (1,3,2,4,5)
Output: 0

Since the array is NOT sorted, it prints 0.

TASK #2 › Long Primes

Submitted by: Mohammad S Anwar

Write a script to generate first 5 Long Primes.

A prime number (p) is called Long Prime if (1/p) has an infinite decimal expansion repeating every (p-1) digits.

Example

7 is a long prime since 1/7 = 0.142857142857...
The repeating part (142857) size is 6 i.e. one less than the prime number 7.

Also 17 is a long prime since 1/17 = 0.05882352941176470588235294117647...
The repeating part (0588235294117647) size is 16 i.e. one less than the prime number 17.

Another example, 2 is not a long prime as 1/2 = 0.5.
There is no repeating part in this case.


Last date to submit the solution 23:59 (UK Time) Sunday 21st November 2021.
