The Weekly Challenge

HEADLINES

Welcome to the Week #316 of The Weekly Challenge.

Today is the first Monday of the month and it’s time to declare the next champion!

With great pride, I announce, Eric Cheung, as the Champion of the Month for March 2025. He was last declared champion in March 2022, exactly three years ago. Eric has been a guest contributor since day one. His favourite languages are Excel VBA and Python. As of today, he shared 63 solutions in Excel VBA and 325 solutions in Python. Currently he is ranked #12 on the Guest Leaders list with a total score of 388.

Eric, please share your PayPal details so that the prize money can be transferred easily.

I’ve noticed a dip in contributions in Perl and Raku but at the same time, there has been growth in others programming languages. If you look at the trend closely, you’ll notice we have a strong and dedicated groups of supporters who regularly share solutions.

One such contributor I’d like to highlight is BarrOff. As of today, he has shared 47 solutions in Perl and 157 solutions in Raku. For a while, he is only submitting solution to Task #1 in Raku. The reason, I’m mentioning him is because despite clearly being busy, he still makes the effort to find time for at least one task each week. That level of dedication deserves a big round of applause.

Interestingly, the timing of his contributions, usually late on Sunday evenings, makes me believe that he’s a busy techie juggling many things. Every time, I aceept and merge his submission, it brings a sense of joy and appreciation.

I would also like to thank, Kjetil Skotheim, for sharing solutions to the past challenges.

Do we have any frontend experts in the team?

Why am I asking?

Well, I am not sure if you’ve noticed, but the top menu bar on the weekly challenge website doesn’t work properly on mobile devices. I finally managed to implement a quick and dirty fix so I can at least navigate the site on my phone. However, it’s still far from perfect.

If you know what’s missing or have ideas for a better fix, please do share your expertise!

By the way, I’ve made few improvements to the Charts page. Please let me know what do you think. Any better?

Last but not least, thank you to the entire team for your continuous support and encouragement. Your dedication keeps this challenge going strong!
