The Weekly Challenge

HEADLINES

Welcome to the Week #331 of The Weekly Challenge.

Let’s all welcome two new members to Team PWC: Harry Wozniak and Fabio Valeri to Team PWC. Both are experienced Perl hackers.

Do you remember our fellow team member, Humberto Massa?

Well, I recently discovered his Raku magics on social media. Another member who shares such insights is James Smith.

I noticed Humberto also posted something like:

@manwar again, from the endoscopy clinic wait room, ... `.

To be honest, this is worrisome. I hope and pray he’s ok.

I’ve copied his one-liners and saved them in the repository, so others can benefit from them as well.

A few years ago, I had to undergo an endoscopy myself. It was one of the scariest moments of my life.

Here in England, the school summer break starts this week. This time, my three school going angels won’t let me stay at home.

So I had to make a last minute booking for a short trip.

Travel Itenary:

- Departing: Saturday  26th July, 2025
- Returning: Wednesday 30th July, 2025

This will slightly disrupt the weekly challenge schedule.

So here’s the plan:

- I'll release the new challenge, Week #332, on Friday night or Saturday morning before leaving.
- This gives you all a couple of extra days to work on it.

There’s another small issue, I won’t be able to process all contributions for Week #331 immediately.

Why? Because some members submit their work on Sunday, so I’ll handle those when I return on Wednesday.

Additionally, my weekly contributions review for the Perl Weekly newsletter, will be partial this time.

Amid all this, I almost forgot to mention that we’ve once again received 100+ contributions once again, the third time in the year 2025 so far.

Well done Team PWC, let’s keep the momentum going strong.

Happy Hacking!!

Task 1: Last Word

Submitted by: Mohammad Sajid Anwar

You are given a string.

Write a script to find the length of last word in the given string.

Example 1

Input: $str = "The Weekly Challenge"
Output: 9

Example 2

Input: $str = "   Hello   World    "
Output: 5

Example 3

Input: $str = "Let's begin the fun"
Output: 3

Task 2: Buddy Strings

Submitted by: Mohammad Sajid Anwar

You are given two strings, source and target.

Write a script to find out if the given strings are Buddy Strings.

If swapping of a letter in one string make them same as the other then they are `Buddy Strings`.

Example 1

Input: $source = "fuck"
       $target = "fcuk"
Output: true

The swapping of 'u' with 'c' makes it buddy strings.

Example 2

Input: $source = "love"
       $target = "love"
Output: false

Example 3

Input: $source = "fodo"
       $target = "food"
Output: true

Example 4

Input: $source = "feed"
       $target = "feed"
Output: true

Last date to submit the solution 23:59 (UK Time) Sunday 27th July 2025.
