For the problem DISHOWN in JULY14 challenge I first tried in C++ 4.3.2 and got TLE
then I uploaded the same code(of course changed cin & cout to scanf and printf) got AC in C.
Admin/Anyone please exlain the reasons for this:
C++ 4.3.2 Submission(TLE): http://www.codechef.com/viewsolution/4284093
C Submission(AC): http://www.codechef.com/viewsolution/4284183
Thank’s in Advance.
Yes ‘cin’ and ‘cout’ are slower than scanf() and printf().To make them faster you can use :
int main() {
ios_base::sync_with_stdio(false); cin.tie(0);
// rest of your code
return 0;
}

@achaitanyasai Does that difference(cin & cout to printf & scanf) will cause this much effect I mean TLE to AC…??
It depends, if the constraints are tight(large) then you may have chance to get TLE if you use cin/cout. But in most of the cases it doesn’t matter.
