python import math 使用factorial函数: 一旦导入了 math 模块,你就可以使用 math.factorial() 函数来计算一个数的阶乘了。 python number = 5 result = math.factorial(number) print(f"The factorial of {number} is {result}") 在这个例子中,math.factorial(5) 将返回 120,因为 5! = 5 * 4 * 3...
For example, the factorial of 6 is 1*2*3*4*5*6 = 720. Factorial is not defined for negative numbers, and the factorial of zero is one, 0! = 1. Factorial of a Number using Loop # Python program to find the factorial of a number provided by the user. # change the value for a...

Given an integer n, return the number of trailing zeroes in n!.Note: Your solution should be in logarithmic time complexity.解析:只有2和5相乘才会出现0,其中整十也可以看做是2和5相乘的结果,所以,可以在n之前看看有多少个2以及多少个5就行了, ...
