Problem statement
INPUT and OUTPUT format

I don't understand why my code is getting wrong?

My approach to making the string non-decreasing as much as possible.

Can anyone please help me to fix my code for this problem or tell me a good approach to solve this problem?

*Now the submit option for this problem is disabled. It will be better if someone comes up with proof of his/her solution.:)
