Time::Str parses and formats date/time strings across 20+ standard formats, with an optional C/XS backend and nanosecond precision. The previous post, Introducing Time::Str, covered parsing and formatting. This one covers two additions, time zones and leap seconds, and ends with a note on the new C parsers. (Reddit)

Welcome to a new week with a couple of fun tasks "Second Largest Digit" and "Sum of Words". If you are new to the weekly challenge then why not join us and have fun every week. For more information, please read the FAQ.

by Mohammad Sajid Anwar (MANWAR)

Enjoy a quick recap of last week's contributions by Team PWC dealing with the "Reverse Existence" and "Prefix Suffix" tasks in Perl and Raku. You will find plenty of solutions to keep you busy.

by Arne Sommer

This article offers a great introduction to the Raku language through its implementation of the The Weekly Challenge #377, specifically the use of native Raku functions, such as .flip and .combinations. The code is well-written, typical of Raku, and fully supported with an extensive breakdown of each line of code, detailed run-time logs, and references to helpful documentation.

by Jaldhar H. Vyas

The article compares Perl and Raku solutions for Week 376 of the Challenge and illustrates how the two languages are different in terms of their evolution. Specifically, it illustrates how Raku provides a more modern set of high-level features (e.g., built-in support for substrings and pairs) compared to the equivalent structural features in Perl, which require additional code to implement.

by Jorg Sommrey

Jorg takes a multi-paradigm approach to solving The Weekly Challenge #377 in both Perl and J (the array-processing language). This article showcases Jorg's technical knowledge because he generalises the first task from its minimum definition and well-organises the second task's input by length to optimise the process. Additionally, Jorg's complete walkthrough of the functional, tacit programming techniques found in language J is well presented, allowing for the easy comprehension of complex manipulations of Arrays and RegEx optimisations.

by W Luis Mochan

W. Luis Mochan employs the expressive capabilities of the Perl language in order to create solutions that exhibit exceptional brevity with no extra syntax or words. This will definitely capture the interest of developers looking for clean and functional solutions.

by Packy Anderson (PACKY)

This post provides a great, multi-lingual breakdown of the challenge with clean idiomatic solutions in Perl, Raku, Python and Elixir. By demonstrating how each of the programming paradigms handle the same logic, Packy provides educational value beyond measure while maintaining interest with a clever Beatles-style music theme.

by Peter Campbell Smith

Peter offers a refreshingly simple and useful way to accomplish this task using only Perl. He places an emphasis on keeping the code readable, ensuring UTF-8 characters can safely contain more than one byte, and maintaining a high level of performance in real-world applications. There is no ambiguity or sacrifice made in developing an easy-to-interpret solution to a hard problem and accommodating corner cases.

by Reinier Maliepaard

In this article, Reinier discusses how to efficiently leverage Perl's string manipulation and logical checks to confirm if input strings share overlapping character sequences with the least amount of code. This article is an excellent resource for learning to write perl code that efficiently performs substring matching in a clear, idiomatic manner with minimal additional complexity.

by Reinier Maliepaard

Reinier made use of Perl's built-in string matching capabilities to efficiently find all pairs where one of the strings serves as both the beginning and end of one of the other strings. This showcases a great example of writing efficient, clear code to solve a complex logic problem of substring containment in as little code as possible.

by Roger Bell West (FIREDRAKE)

Roger's article provides an excellent comparison between different programming languages by demonstrating how language paradigms solve the same algorithms for sliding windows and substring matches, thereby providing significant educational value to the reader by making comparisons between high-level built-in functions with manual implementations for the same problem.

by Simon Green (SGREEN)

In this post, Simon analysed the issue into smaller pieces/steps made it easier for implementation to remain very readable and maintainable. A strong resource for developers wishing to observe how simple, idiomatic methods can more elegantly achieve string manipulating constraints.

Great CPAN modules released last week.
