Problem Description:In mathematics, the factorial of an integer is n written as n! . It is equal to the product of and n every integer preceding it. For example:5! = 1 x 2 x 3 x 4 x 5 = 120Your mission is simple:write a function, takes an integer and n returns the value of n! .You is guaranteed an integer argument. For any values outside the Non-negative range, return null , nil or None (return a empty string "" in C D C + +). For non-negative numbers

### HDU 1124 factorial (factorial suffix 0)

Test instructions: Give a number n, return its factorial result suffix has several 0.Ideas:First, the decimal quality factor is decomposed to 2*5=10. The n! mass factor decomposition, then decomposition, which should contain a min (2 number, 5 number) suffix 0.Why do you say that? For example N=15, then {1 2 3 4 5 6 7 8 9, then you can generate 2 of the number has {2,4,6,8,10,12,14}, can produce 5 of only {5,10,15} , only 2 times 5 in prime numbers t
