For testing how long it takes to execute a loop of 10^9 turns, I have come up with a wonder that the code gets AC within 15 ms!!!!! Though the loop part is not related to the solution. Then I did the same with one extra nested loop and still the time taken was 15 ms :D I chose problem 592B - Белочка и чудовище for the test and my code is : http://pastebin.com/LpskC8Ti

How is that possible???
