Yes many have the same problem: code too slow...

Hi,

that means that, even if your code output the correct result, it's not fast enough (hence, not "good enough"). => you need to change your approach to have a better time complexity.

cheers

I wrote good code, but all time I get "Timed Out", such anoying feeling :P
Anybody else have the same problem?

Why the replace? And normally when you use split, you'll want to use another method to join them again, not doing it manually.
