wtf so there is a pattern?!

Slow but nice and simple.

And after that, try to do it with only one single pass over the input! That is, look at each character only once. ;-)

I had some errors on the random tests and I still got it through by brute forcing it, and doing it a bunch of times. That should probably be fixed.

Probably a 6

What kata rank would you give this one (for Python)?

Please, could you explain the solution? I'm kinda lost on what was done and why it worked.

Thanks

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 :/
