Is printf faster than cout in C++ or not?
By pwn, 12 years ago, In English

Please have a look at these two solutions, the code using cout is accepted but the code using printf is giving TLE. I always thought printf is faster than than cout. What do you think?

I don't know for sure but maybe you have TLE on the first submission because of combining cin and printf? Try to use stdio only

Firstly, your solution is really slow.

Secondly http://codeforces.me/contest/436/submission/6890816 scanf is faster than cin, but i guess printf is slower when it comes to long long int.

Anyway if you have right solution it doesn't matter if u're using cout or printf :)

EDIT: Check this ( I've changed your solution so i can use int everywhere )
