i don't know about your approach but i think the difference of the number of 0s and 1s in the string solves the problem (as you can always eliminate one 1 and one 0 from the string so remaining extra will be the ans)

I think you are using std::string::erase wrongly. Please read some documentations if you are unsure of what you do.

In your specific case, I'm understanding that you want to erase index i and i+1; in which case, the correct call should be str.erase(i, 2) instead of str.erase(i, i+1).
