Depth-First Search (DFS)
A Tree Traversal Technique Using Recursion
Introduction
Depth-First Search (DFS) is a tree traversal algorithm that starts from the root and explores as far as possible down each branch before backtracking. It systematically visits each node in the tree, diving deep into each branch before moving to the next one. DFS is commonly implemented using recursion. It is useful for tasks like searching for a particular node, determining if a tree is balanced, or finding paths in the tree.
