The Weekly Challenge

HEADLINES

Welcome to the Week #335 of The Weekly Challenge.

Thank you, Yitzchak Scott-Thoennes, for your prompt reply and for confirming the prize money transfer.

I noticed a surprising dip in contributions last week and I’m not sure what the reason might be.

I hope everyone is enjoying the weekly challenge!

If you ask me, I would say, I particularly enjoy reading the discussions on various social platforms.

I would also encourage all Team PWC members to share their magical code with a wider audience.

Happy Hacking!!
