cool, it is make to think, great!

I think some people here are trying to solve the problems without the (in this case) given string methods. They probably just wanna stimulate their minds.

what is the i = 0 for?

Love that a for loop isnt used. Makes perfect sense !

Good one. Me like. :D

you could do .replace instead.I wouldn't say its inefficient tho I'd just say there's better ways

Elegant code man! Took me a while to get it, actually i had to use a piece of paper to understand your code. Super impressive!

Time complexity is like O(n^2) why? figure it out Lol

ocelot269 would benefit more if you would explain why it is inefficient...

This one's pretty good!

inefficient

best for me
