Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it.Brian W. Kernighan

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.
