# Code to find factorial on num # number num = 4 # 'fact' - variable to store factorial fact = 1 # run loop from 1 to num # multiply the numbers from 1 to num # and, assign it to fact variable for i in range(1, num + 1): fact = fact * i # print the factorial print(...
Write a function to calculate the factorial of a number. The factorial of a non-negative integer n is the product of all positive integers less than or equal to n. For example, for input5, the output should be 120 1 2 def factorial(n): Check Code Share on: Did you find this...
n = int(input('n = ')) print(factorial(m) // (factorial(n) * factorial(m - n))) # factorial函数也是内置函数,事实上要计算阶乘可以直接使用这个 # 现成的函数而不用自己定义 # 通过导入的math模块,来调用factorial函数来求阶乘运算 import math m = int(input('m = ')) n = int(input('n...

__doc__ return func @tail_call_optimized def factorial(n, acc=1): "calculate a factorial" if n == 0: return acc return factorial(n-1, n*acc) print factorial(10000) 为了更清晰的展示开启尾递归优化前、后调用栈的变化和tail_call_optimized装饰器抛异常退出递归调用栈的作用, 我这里利用 pudb...
Input: 5 Output: 1 Explanation: 5! = 120, one trailing zero. Note: Your solution should be in logarithmic time complexity. 思路: 在n!中,若想在结果的结尾产生0,只能是5乘以双数、或者某个乘数结尾为0,如10,但10可视为5*2,20可以视为5*4. ...
