This solution is based on the length of the resulting string, so replacing with spaces won't change the length of the initial string because space is still counts towards the length as 1 character, while you want to get the length of the string consisting only from remaining chars.

I did the same thing but I replaced it with the space instead of ''. Can someone explain me please why my version didn't work (it sometimes had more numbers) but this one does? If in the description it's told that there should be spaces :/

:shrug:

Your question is basically the same as someone asking Why are you 5kyu???? o_O

the one and only solution

It's not just a solution but a script. Great work!

This kata is old and has been solved many times. Its design won't be changed since it would invalidate all submitted solutions.

bruh. input validation in an 8 kyu? not to mention it's uneccessarily confusing with the different results expected for positives and negatives. maybe look into changing those things

Because 9 kyu isn't an option?

I mean... how come this kata's rank stands at 8 kyu??? Smh...

The unmatched power of RegExp!

It's a joke, isn't it?

The only way to solve this kata

I just feel like to say that I like your solution the most
