![]() ![]() How Do I Construct a Recursive Algorithm? However, keep in mind that recursive solutions can be less memory efficient and if your machine’s memory is exhausted or your function’s stack is too deep before reaching the base case, it will cause a stack overflow error. It is more intuitive when solving solutions that are recursive in nature, as we will see in examples later. ![]() When used correctly, a recursive solution usually results in cleaner code that is easier to read. Some canonical examples of recursion problems are calculating the nth Fibonacci number, calculating the factorial of a number, and converting decimal numbers into binary numbers. This includes graphs, trees and data structures that have a parent-child relationship. Recursion is frequently used for problems that are recursive in nature. The way recursion works is by solving the smaller subproblems individually and then aggregating the results to return the final solution. Recursion is when a function or method calls itself and is essential to the divide and conquer paradigm, whereby the idea is to divide bigger problems into smaller subproblems and the subproblem is some constant fraction of the original problem. In this article, I will explain what recursion is, when to use it and walk through some examples written in Python 3. Recursion is a fundamental concept in programming when learning about data structures and algorithms. ![]()
