1. 问题要求编写一个计算数字阶乘的Python函数。2. 阶乘定义:n! = 1×2×3×...×n,其中0! = 1,负数没有阶乘。3. 函数首先处理n为负数的情况,抛出ValueError异常。4. 初始化结果为1(兼容n=0和n=1的情况)。5. 使用循环从2开始累乘到n,避免递归可能导致的栈溢出问题。6. 该实现时间复杂度为O(n),空间复

2. Find factorial using Recursion To find the factorial,fact()function is written in the program. This function will take number (num) as an argument and return the factorial of the number. # function to calculate the factorialdeffact(n):ifn==0:return1returnn * fact(n -1)# Main code...
actually a function from the maths library of python. It is similar to scipy.math.factorial(). The function computes the factorial of positive numbers. It does not work for input arrays. In order to calculate the factorial of an input array, consider using scipy.special.factorial() function....

Output: 0 Explanation: There is no x such that x! ends in K = 5 zeroes. Note: K will be an integer in the range [0, 10^9]. 借助上一题的思路来做,显然阶乘的0的个数每隔5个数变化一次(0~4,5~9……),本题需要找到是否存在N,f(N)=K,如果存在则返回5,不存在返回0。根据数学推导N>...
