decimal factorial

Test instructions: Given two numbers A and B, how many consecutive 0 of the output (1) suffix is obtained after the factorial of a is converted to B-binary ? (2) How many people are there? Idea: Solve the problem one by one.Set A!  =k. K

 Abstract: This article uses an algorithm idea that is almost the same as "computing of big data factorial from entry to entry". It is different from the previous article in this article, the program given in this article uses an array element to

Don't be intimidated by factorial. DescriptionFactorial (factorial) is a very interesting function, but a lot of people are afraid of it, let's look at two factorial-related problems:Question 1. Given an integer n, then the factorial n of n! How

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

Input:Enter 1 positive integers per line n, (0Output:For each n, the number of (decimal) digits of the output n!.Analysis:This problem uses brute force method. By definition, direct solution!The so-called n! decimal digits, is log (n) +1, according
