The Weekly Challenge

HEADLINES

Welcome to the Week #332 of The Weekly Challenge.

This is an early release the weekly challenge, as I mentioned last week about my planned short holiday trip with family.

I felt it was time to take a break as our last family trip was exactly two years ago, a three weeks visit to India.

This time, we’re exploring a different part of the world, as the reason behind our previous trip to India trip no longer exists.

I lost both my parents 2 years ago.

Thank you all for the kind messages, they truly mean a lot to me.

Some late contributions to Week #331 made it the best week of 2025 so far.

It’s 2:00 AM on Saturday and I’m releasing the next weekly challenge, two days early.

Any contributions from now on will be processed when I return on July 30, 2025.

Happy Hacking!!
