Introduction
Embarking on the journey of graph traversal opens the door to two fundamental algorithms: Breadth-First Search (BFS) and Depth-First Search (DFS). These techniques play a pivotal role in various computer science applications, each with its unique strengths and applications. In this article, we delve into the Difference Between BFS and DFS to provide a comprehensive understanding of their mechanisms, use cases, and intricacies.

Exploring the Fundamentals
- BFS: Navigating the Breadth
BFS, as the name suggests, explores a graph layer by layer, starting from the root. This section unveils the mechanics behind BFS and its specific characteristics that distinguish it from DFS.
- DFS: Delving into the Depths
In contrast, DFS takes a plunge into the depths of a graph, exploring as far as possible along each branch before backtracking. Here, we unravel the nuances of DFS and its unique approach to graph traversal.
