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
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

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:
