Factorial computing from entry to entry-entry 2

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 represent 4-or 9-bit 10-digit numbers, which makes the calculation faster and saves more memory. This article provides two factorial functions. The program code is

Python Learning--several methods of calculating factorial __python

Method One:Very common for loop statement: A = 1 n = 5 for i in range (1,n+1): a = a * I print (a) Get the result: 120 Method Two:Use the reduce () function mentioned in the previous blog post: From functools import reduce n = 5 print (Reduce (lambda x,y:x*y,range (1,n+1)) Get the result: 120 Method Three:Using recursion of functions: def factorial (n): if n = = 0 or n = 1: return 1 else: return (N*

Big Data factorial

Under normal circumstances, a factorial is multiplied by 1 by 2 by 3 by 4 until it reaches the required number, that is, the natural number N factorial. The following code uses int to calculate the factorial result: int SmallFactorial(int number){ int sum = 1; for (int i = 1; i Test results: When the factorial

Java implementation factorial algorithm

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

To summarize the various methods of seeking factorial ha.Written in the front: ① Each code is just to provide the idea of factorial, so that when the actual need to encode, code is not robust! ② each program is tested correctly within 1 to 10.Code One:#include Analysis: The program calls FAC () each time it enters N, to calculate the result by brute force.Code two:#include Analysis: The program uses an arra

Factorial is the rightmost 0-bit

/* Description Perhaps you already know the meaning of factorial, n factorial is produced by multiplying 1 to N, such as: 6! = 720. Therefore, the factorial of 6 is the rightmost 0-bit 2. Write a program that calculates the rightmost 0-bit value of N (1
