The Weekly Challenge

HEADLINES

Today is the first Monday of the month and I eagerly wait for this moment to declare the next Champion of PWC. It is not just about the prize money but it gives me reason to celebrate the contributions of another Champion. And there is a bonus on top of it, I get to interview the Champion and find out more about him/her.

So who is the next Champion?

Well, I am happy to announce, Pete Houston (United Kingdom), as our next Champion. Just for record, he never blogged about his solutions and he always email his contributions as attachments. I appreciate his consistent contributions. He is currently ranked #34 with score 198 in the Leaderboard.

Last week was a bit odd as I was little disturbed and out of my happy zone. It resulted in no contributions, code or video, from me, sorry. I will try to compensate this week. However, I did write a blog about the same on 4th June 2021, please check it out when you have spare time.

I have received many supportive messages and suggestions from Team PWC members. I thank each and everyone for taking time out and sharing ideas. I would like to mention one name specifically, Bartosz Jarzyna. He wrote the blog presenting his views. It started discussions on Facebook and Reddit. I have read each and every messages. I try to stay out of the discussion in public. I personally prefer one-2-one private discussion.

Bartosz even contributed to this week challenge in Perl after a gap of 6 weeks. He even shared a very detailed blog following the style he recommended in his other blog. Thank you Bartosz.

Thank you, Dave Cross, for the second consecutive week contributing in Perl.

Welcome back, Paulo Custodio, after a short break and thanks for sharing Perl solutions to Week #108 and Python solutions to Week #4.

5. Stars: 91

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.

TASK #1 › Number Sequence

Write a script to split the given number such that the difference between two consecutive numbers is always 1 and it shouldn’t have leading 0.

Print the given number if it impossible to split the number.

Example

Input: $N = 1234
Output: 1,2,3,4

Input: $N = 91011
Output: 9,10,11

Input: $N = 10203
Output: 10203 as it is impossible to split satisfying the conditions.

TASK #2 › Sum of Squares

Submitted by: Mohammad Meraj Zia

You are given a number $N >= 10.

Write a script to find out if the given number $N is such that sum of squares of all digits is a perfect square. Print 1 if it is otherwise 0.

Example

Input: $N = 34
Ouput: 1 as 3^2 + 4^2 => 9 + 16 => 25 => 5^2

Input: $N = 50
Output: 1 as 5^2 + 0^2 => 25 + 0 => 25 => 5^2

Input: $N = 52
Output: 0 as 5^2 + 2^2 => 25 + 4 => 29
