Input: int n = 0; Output: res = 1 Factorial of 0 is always 1. Finding Factorial using Iteration In the iterative approach, we use a loop like for or while to multiply the numbers in descending order to get the factorial. Example In this Java program, we find factorial of a number...
for just such repetitive operations. Methods are contained areas of a program that may be called to perform operations on data. They take a specific number of arguments and return an output value. The following is an example of a method that takes in an integer and returns its factorial: ...
publicstaticintfactorial(int n){if(n==0){return1;}else{returnn*factorial(n-1);}} 在这个示例中,当函数被调用时,它会检查参数n是否等于0。如果是,则返回1,因为0的阶乘等于1。否则,它会递归调用自身,传递参数n-1,并将结果与n相乘。这个过程会一直重复,直到n等于0为止。最后,所有的乘积会被返回作为结...
