Is there something like leetcode for string manipulation exercises like this?

aarongray Jul 6, 2015 View on HN

That's an impressively long string.

Why waste time type lot char, when few char do trick

EcmaScript all over again. As I understand, letter reversal doesn't count?

LLMs aren't very good at string operations. They struggle with things like character counts, extracting substrings, and replacements.

asking a LLM to do letter manipulation is cruel. Why not ask it to do something useful?

except they did it with 7 characters :)

It's more characters than manual way. There should be just a built-in function.

Just used cBfHcKrzAuacakTW - thanks!

Cool idea btw "love", "coffee" example doesn't work
