You still have to go over the string's length.

I really love this solution.

no spoilers

It is true, but it would be an idea to be able to execute it without errors

Hi.

I hope you are well, today the code doesn't work, I'm just going to study it, it's super

bravo !! very clever solution

This is really cool, if you want to waste your coworkers time

I am here, too! I just spent hours on another kata writing an iterative solution that also preserved the data type of "int" rather than first transforming the input to a "string". I was so proud. Once I viewed the solutions, there shined a Linq one-liner. I'm sure there's value in being able to write iterative solutions, but, there comes a point that it just doesn't make as much sense. (Like right now) lol Did you find any good, hard resources for Linq? As of now I'm doing as Aelion and kvarcas91 are suggesting

Or, you can always check other solutions, analyze them and then implement it.

Yoo, so unreadable. And one more thing. You don't have a check for the input parameter to be less than zero.

This solution is 8 times slower. "For" and "if" are better.

Why Kata test excludes negative number?
