This seems to be a number theory problem, but here's my python solution for this.

 1 2 3 from math import factorial print(str(factorial(2015)).count('0')) #Returns 1037, time taken=6ms

Wheyy....you know python too? I thought you used C++ for CS!

Yeah I learnt python about a month ago due to lack of required data types in C++. Also, I am posting solutions in python now-a-days.

I do not like pythonic answers, I like traditional mathematical thinking and logical reasoning. Any body has a mathematical answer?
