Welcome to the Depth-First Search and Breadth-First Search Tutorial

Understanding DFS and BFS

Depth-First Search (DFS) and Breadth-First Search (BFS) are fundamental algorithms used for traversing or searching tree or graph data structures.

Depth-First Search (DFS)

DFS algorithm starts at the root (selecting some arbitrary node as the root in the case of a graph) and explores as far as possible along each branch before backtracking.

Breadth-First Search (BFS)

BFS algorithm starts at the tree root (or some arbitrary node of a graph) and explores all of the neighbor nodes at the present depth prior to moving on to nodes at the next depth level.
