Recursion is an important concept in computer programming that refers to the process of repeating items in a self-similar way. In other words, a function that calls itself is said to be recursive. At its core, recursion is a way for a function to solve a problem by breaking it down into smaller, simpler subproblems. These subproblems are then solved recursively, and the solutions to the subproblems are combined to produce a solution to the original problem. One of the key advantages of recurs...
