factorial calls it factorial, as Wikipedia describes the " factorial of a positive integer is the product of all positive integers less than and equal to that number, and has a 0 factorial of 1 ." nthe factorial writing n! of natural numbers . ”The
Big Number Problem: Calculate the factorial of n and the factorial of n for the big number.
Question: 100!
This seems to be a simple answer, and recursive solutions are not under pressure.
int func(int n){ if(n But you will find that the question is really so simple, consider whether the integer data does not cross the border?
This is actually a big number problem!

Many programming books have introduced factorial. I believe that everyone, including me, can read it and never think about other problems in depth. For example, in the range of Integers (C #), how much can a
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

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 temporarily does not have to go directly into the B-system.(1) Factorial suffix 0 problem. First look at this example of the decimal suffix 0 : http://www.cnblogs.com/xcw07

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
Logop1134 factorial problem, logop1134 factorialDescription
Maybe you have long known the meaning of factorial. N factorial is generated by multiplying 1 to N, for example:
12! = 1x2x3x4x5x6x7x8x9x10x11x12 = 479,001,600
The rightmost non-zero digit of the factorial of 12 is 6.

Description
Calculate the factorial of n less than 10000.
The original address of the article: http://blog.csdn.net/zyh2525246/article/details/53697136
When the order multiplier is small, it can be calculated directly.
For example: Ask for 10. The number of the following 0. The result is obviously 3628800. The number of 0 is 2.
20. The result is a number of 4 2432902008176640000,0. And this time has reached the 19-digit number.
A larger number, if you go straight to the request. It's obviously too much trouble.
