Data Structures and Algorithms The Complete Masterclass - Implementing Depth-first Search - Algorithms: Graph Traversal

The video tutorial introduces Depth First Search (DFS), explaining its strategy and comparing it with Breadth First Search (BFS). It covers the implementation of DFS using recursion, detailing the traversal logic and node visitation process. The tutorial includes code execution and output analysis, followed by testing and modifying the DFS implementation to demonstrate recursion's benefits.

Explain how recursion is utilized in the DFS method.

What steps are taken when selecting adjacent nodes in DFS?

How can the DFS algorithm be tested after implementation?
