I have only two coordinates on a plane, and just read input. Nothing more and my prog works 0,046 sec. But in statistics there are AC's in 0,001 sec.

I wonder how can it be???

Quicker reading.
For example, scanf is quicker than cin.
And gets + atoi is better than scanf("%d")

Replacing scanf->gets,atoi seems not to be enough
