What is an example of a recursive process?

An example of a recursive process is the calculation of the factorial of a number, denoted as n!. The factorial of n is defined as n multiplied by the factorial of (n-1), with the base case being that 0! equals 1. This process continues recursively until it reaches the base case, effectively breaking down the problem into smaller subproblems. For instance, to calculate 5!, the process would be 5 × 4! → 5 × (4 × 3!) → 5 × (4 × (3 × 2!)) and so on until reaching 1.
