The Weekly Challenge

HEADLINES

Welcome to the Week #313 of The Weekly Challenge.

Thank you, Kaushik, for back to back contributions in Perl and blog post.

I don’t know if noticed this, there is a drop in Raku contributions.

We have some rock solid Raku supporters in the team. I am sure they can bring in more Raku hackers.

I am still waiting for the 100+ contributions week of the year 2025. The closest we reached so far, was in the Week #309 and the number was 90.

Guest contributions have been on the rise all the time, never a dip in that front.

Keep the energy up and stay safe.

Last 5 weeks mainstream contribution stats. Thank you Team PWC for your support and encouragements.

Task 1: Broken Keys

Here "r" is pressed 3 times instead of 1 time.

Example 2

Input: $name = "raku", $typed = "rrakuuuu"
Output: true

Example 3

Input: $name = "python", $typed = "perl"
Output: false

Example 4

Input: $name = "coffeescript", $typed = "cofffeescccript"
Output: true

Task 2: Reverse Letters
