The factorial algorithm is as follows: 0 to 20 of the factorial: 0! =1, (the factorial of 0 is present) 1! =1,2! =2,3! =6,4! =24,5! =120,6! =720,7! =5040,8! =403209! =36288010! =362880011! =3991680012! =47900160013! =622702080014! =8717829120015! =130767436800016! =2092278988800017! =35568742809600018! =640237370572800019! =12164510040883200020! =2432902008176640

Found with a long type, the result of running the output is 0, this is not true,What is the reason? Debug with debug found, 100! Data is too large, long data storage space 8 bytes is not enough to overflow.So wha

Given an integer n, return the number of trailing zeroes in n!.Note: Your solution should is in logarithmic time complexity.Credits:Special thanks to @ts for adding this problem and creating all test cases.See for a long while did not read the title meaning to ask N end 0 of the number of a half-day is required n! That is, the factorial of n results in the end of how many 0 can be known when the factorial
