Depth First Search (DFS) is a fundamental algorithm used to explore or search through data structures like trees and graphs. Think of it like exploring a maze by always going as deep as possible down one path before backtracking. Once you understand how DFS works conceptually, the next step is learning how to actually implement it in code. This article explores the common ways DFS is brought to life through programming.
