Implementing Depth-first Search

The video tutorial explains Depth First Search (DFS) in detail, comparing it with Breadth First Search (BFS). It covers the implementation of DFS using recursion, demonstrating how to traverse a graph by visiting nodes and marking them as visited. The tutorial includes a practical coding example, showing how to execute and test the DFS algorithm, and concludes with a brief discussion on the benefits of using recursion for simplifying code.
