It allowed me to share whatever was on my mind at the time. And when I receive encouraging responses, it gives me even more motivation to keep going.

Equally Sorted

A very special construct used, never tried it before: unless-else-redo unless. This is incredible. Keep sharing the knowledge with us.

TWC314

I wouldn't say short as per his standard but agressive use of substr() would make you look at it very carefully. Cool work and well done.

Sort of Equal

When it comes to detailing, no one can beat him. There's hardly anything left for imagination. Everything is documented. Great work, keep it up.

Monotonous Prefixes

Another week another creative regex in display. Enjoy and decode it yourself. Have fun!!

Perl Weekly Challenge 314

Master of one-liner, once again surprised us with variations. Well done and keep it up.

Count Any Zipped Column

Simply love the story from start to finish. Great naration and beautiful solution. Keep it up and well done.

Even more strings

Smart move for catching the edge case. Well documented solution and bonus DIY tool as always. Super cool, keep it up.

The Weekly Challenge #314

It's incredible how you find the edge cases and then presented with choices. Kudos for your effort, keep sharing your knowledge with us.

Stringy Column

Raku rocks!! Basic non-recursive array comparator in Raku worth checking. This is cute. Thanks for sharing and well done.

Sorted equally

Here you go, Python at it's best. Never seen this construct: if-for loop. Python is a free bird, you can't catch him. Thanks for your contributions.
