WebMar 31, 2024 · In this example, we define a function called factorial that takes an integer n as input. The function uses recursion to compute the factorial of n (i.e., the product of all positive integers up to n). The factorial function first checks if n is 0 or 1, which are the base cases. If n is 0 or 1, the function returns 1, since 0! and 1! are both 1. WebFeb 16, 2024 · Here we have shown the iterative approach using both for and while loops. Approach 1: Using For loop.
