The beauty of programming should not be intimidated by the factorial, but the beauty of 2.2. When I first saw this question, I thought it was the idea to use a string to represent the integer number. Later I saw that because it is a factorial of a number, if it is large, therefore, it is unreasonable to use the string representation. After reading the explanation of this question, the book gives a formula a

Problem description: given an integer N, the factorial n of n! How many zeros are there at the end? Example: n = 10, n! = 3628800, n! There are two zeros at the end Analysis of the problem: Calculate the factorial of N and then check whether there are many zeros that are not practical. If n is slightly larger, it will take a lot of time. So let's analyze when we will add a zero, when there is a multiple of

If you want to implement a factorial, such as 6*5*4*3*2*1, you may first think of loop traversal. As follows: class Program { static void Main(string[] args) { Console. writeline ("enter a number "); int number = Convert.ToInt32(Console.ReadLine()); double result = JieCheng(number); The factorial result of console. writeline (number. tostring () + "is:" + res

Today, I went around for a boring search and asked: Who can provide detailed procedures for the 20 factorial in vbs? The answer is as follows:Copy codeThe Code is as follows: function jx (x)J = 1For I = 2 to xJ = j * INextJx = jEnd functionMsgbox jx (20) Run the above program and output 2.43290200817664E + 18.

In the joint iflab of the new question and answer on the book to see such a question, the effect is:Give an integer n, ask N! How many 0 are at the end of (N's factorial)?Because when n is very big, it is forced to calculate n! is impossible, so must find another way to solve the problem.First of all, why would there be 0 at the end? Because 2*5 = 10,0 just came. So just ask out this n! How many of the 2 how many 5 times better, because 2 of the numbe

Question one: Given an integer n, how many 0 are there at the end of the factorial of n? For example n = ten, n! = 362800,n! There are two 0 at the end.Question two: Ask N! The position of the lowest bit 1 in the binary representation.Solution one of the problem one:The simplest way is to put n! Figure out, you can know how many 0 at the end.Solution two of problem one:We think so, at the end of the 0 can be obtained from where, a multiple of 10, such

The Stirling formula is a mathematical formula used to approximate the n factorial. In general, when N is very large, the calculation of n factorial is very large, so the Stirling formula is very useful, and even when N is very small, the Stirling formula is very accurate: When the Stirling formula is used to calculate the number of bits of the n! result, the logarithm can be taken on either side:
