In problem D. Mahmoud and Ehab and the binary string my submissions are failing with "wrong answer Couldn't find an answer" :( My last try is this. I checked other users solutions, but I can't find what is wrong with my code.

Hello,
Just analysed your code a bit and submitted it after one modification : Submission after code Edit
I've just inversed the positions in the printf. You need to recheck your find_one & find_zero ...
I was sure that it is caused by "Couldn't find an answer". Apparently this error message means "wrong answer" OR "Couldn't find an answer", not AND.
Thank you for help.
