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)
Try to solve it using stack. Here's my solution:SOL
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
andi+1
; in which case, the correct call should bestr.erase(i, 2)
instead ofstr.erase(i, i+1)
.
