Spoiler Alert: This weekly challenge deadline is due in a few days from now (on July 21, 2024, at 23:59). This blog post provides some solutions to this challenge. Please don’t read on if you intend to complete the challenge on your own.
Task 1: Sort String
You are given a shuffle string, $str.
Write a script to return the sorted string.
A string is shuffled by appending word position to each word.
Example 1
Input: $str = "and2 Raku3 cousins5 Perl1 are4"
Output: "Perl and Raku are cousins"
Example 2
Input: $str = "guest6 Python1 most4 the3 popular5 is2 language7"
Output: "Python is the most popular guest language"
Example 3
Input: $str = "Challenge3 The1 Weekly2"
Output: "The Weekly Challenge"

Half of my new modules were related to my password framework Crypt::Passphrase. To be honest most of them are either small (± 100 LOC) glue two or three other pieces of code together. And then there was Crypt::HSM, a PKCS11 interface (to use cryptographic hardware without exposing cryptographic keys) that was probably more work (2600 LOC of XS) than the others combined.
Most of this was with the aim to add peppering support to Crypt::Passphrase, a subject extensive enough that I should probably dedicate a separate blogpost to it.

Task 1: Count Common
You are given two arrays of strings, @words1 and @words2.
Write a script to return the count of words that appears in both arrays exactly once.
Example 1
Input: @words1 = ("Perl", "is", "my", "friend")
@words2 = ("Perl", "and", "Raku", "are", "friend")
Output: 2
The words "Perl" and "friend" appear once in each array.
I missed last year but in 2024 I'm doing a dev release of Perl again. This time it is version 5.39.7.
And again, you can watch it live on Saturday 20th of January on Twitch.
Well, not actually wrong, just slow. But the exaggeration makes a punchier headline, you’ll admit.
This comes up when an interface takes a pattern to match things against. Sometimes you have some reason to want this match to always fail, so you want to pass a pattern which will never match. The customary way of doing this is to pass qr/(?!)/. There is a problem with that, though.
I’m not talking here about the fact that if possible, you really don’t want to pass an actual qr object. We’ve already covered that. It was a surprising enough discovery that I’ll take this opportunity to signal-boost that while we’re here, but this article is not about that.

Task 2: Maximum Frequency
You are given an array of positive integers, @ints.
Write a script to return the total number of elements in the given array which have the highest frequency.
Example 1
Input: @ints = (1, 2, 2, 4, 1, 5)
Ouput: 4
The maximum frequency is 2.
The elements 1 and 2 has the maximum frequency.
We’re given a grid with obstacles, we’re supposed to count all the reachable plots in the grid in a given number of steps (we can only move one plot at a time horizontally or vertically).
DBD::mysql has long provided the interface to connect to the MySQL database from Perl code. But as old as it is, it was implemented with some critical bugs that cannot simply be corrected without breaking mountains of existing code relying on those bugs. For this same reason, though DBD::MariaDB corrects these bugs, care must be taken when migrating existing code to avoid subtle breakage.

Task 2: B After A
You are given a string, $str.
Write a script to return true if there is at least one b, and no a appears after the first b.
Paul volunteers to do the 5.39.9 release. We still need people for .10 and 5.40. The .10 release will be timed around PTS - so maybe we could do something “live” at the summit?
Mailing list was otherwise quiet so there weren’t many issues to discuss.
In absence of many other pressing issues, we spent some time thinking ahead to large-scale development work that might take place in the 5.41 series. We talked about “hooks” as a potential long-term thought to making a more powerful Magic-like structure, for implementing new features, attributes, etc..
I am very pleased to announce that the 2024 Perl & Raku Conference Planning Committee (TPRC) is moving forward with the addition of a new track that targets academic, governmental, and industrial STEM applications. It will strive to be organized as a traditional science conference track; meaning the talks will be based on paper and poster submissions. (more on this in a future announcement!)
The decision by the TPRC Planning Committee is the result of an overwhelmingly positive response to the Science Track Survey that was held late in 2023. Everyone involved in organizing the survey deeply appreciates those who filled out the survey or shared it with others.
The track is being organized in tight cooperation with the TPRC, by the Science Perl Committee (SPC); a separately organized group of Perl and STEM enthusiasts that anyone of good will is welcome to join.
