i had runtime error in this submission and i was going crazy finding where the error is
after 2 hours of debugging and tracing .. i didn't find the problem .. i did something stupid and the problem got accepted .. i don't know why actually ...
does any one knows where was the error in the first code ? ?
and why C++ behaves like that
