Good code is its own best documentation. As you're about to add a comment, ask yourself, 'How can I improve the code so that this comment isn't needed?' Improve the code and then document it to make it even clearer.Steve McConnell

Trailing zeros are a sequence of 0s in the decimal representation of a number, after which no other digits follow. Example 320 has one tailing zero.

The number if trailing zeros in the representation of factorial. The factorial is not negative integer number which is the product of numbers.

Example:-

Input 23, the factorial calculated by

23! = 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x 10 x 11 x 12 x 13 x 14 x 15 x 16 x 17 x 18 x 19 x 20 x 21 x 22 x 23

23! = 25852016738884976640000

Result = 4.
