1. Find factorial using Loop # Code to find factorial on num# numbernum=4# 'fact' - variable to store factorialfact=1# run loop from 1 to num# multiply the numbers from 1 to num# and, assign it to fact variable
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...

Finding power of a number: Here, we are going to implement a python program to find the power of a given number using recursion in Python.
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. ...
