In competitive programming, it is common for many programmers to use
printf() in C ++ code instead of using
And I've even seen problems that result in a Time Limit Exceeded (TLE) when used
cout , but run within time when
scanf() is used
printf() , implementing the same idea in the algorithms.
Then there is the question,
scanf() is always faster than
cin , will it depend on the case or
cin is faster?
