The Weekly Challenge

HEADLINES

Welcome to the Week #320 of The Weekly Challenge.

This edition of the weekly challenge comes to you from Germany as I am attending the Perl Toolchain Summit 2025 in Leipzig.

Since I will be traveling back home on Sunday night, there may be a few missing bits when the challenge goes live.

Don’t worry, I’ll patch things up by Monday afternoon once I’ve arrived home.

In the meantime, you’ve got the challenge to play with, so please keep the momentum going!

We’re excited to welcome a new member, HVukman to Team PWC.

Thank you, HVukman, for sharing your first contributions in K.

Tomorrow marks the first Monday of the month and time for our monthly ritual!

I’m pleased to announce, Vinod Kumar K, as our next Champion of the Month.

A gentle reminder to last month’s champion, Eric Cheung, I’m still waiting for PayPal details.

Vinod and Eric, please share your PayPal account information and preferred currency for the prize money.

Thank you, Roger, for adding another programming language, Typst to our list of guest languages. It looks simple and easy to use.

Keep Hacking and sharing knowledge!

Task 1: Maximum Count

Submitted by: Mohammad Sajid Anwar

You are given an array of integers.

Write a script to return the maximum between the number of positive and negative integers. Zero is neither positive nor negative.

Example 1

Input: @ints = (-3, -2, -1, 1, 2, 3)
Output: 3

There are 3 positive integers.
There are 3 negative integers.
The maximum between 3 and 3 is 3.

Example 2

Input: @ints = (-2, -1, 0, 0, 1)
Output: 2

There are 1 positive integers.
There are 2 negative integers.
The maximum between 2 and 1 is 2.

Example 3

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

There are 4 positive integers.
There are 0 negative integers.
The maximum between 4 and 0 is 4.

Task 2: Sum Difference

Submitted by: Mohammad Sajid Anwar

You are given an array of positive integers.

Write a script to return the absolute difference between digit sum and element sum of the given array.

Example 1

Input: @ints = (1, 23, 4, 5)
Output: 18

Element sum: 1 + 23 + 4 + 5 => 33
Digit sum: 1 + 2 + 3 + 4 + 5 => 15
Absolute difference: | 33 - 15 | => 18

Example 2

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

Element sum: 1 + 2 + 3 + 4 + 5 => 15
Digit sum: 1 + 2 + 3 + 4 + 5 => 15
Absolute difference: | 15 - 15 | => 0

Example 3

Input: @ints = (1, 2, 34)
Output: 27

Element sum: 1 + 2 + 34 => 37
Digit sum: 1 + 2 + 3 + 4 => 10
Absolute difference: | 37 - 10 | => 27

Last date to submit the solution 23:59 (UK Time) Sunday 11th May 2025.
