Implementing Breadth-first Search

The video tutorial explains the implementation of Breadth-First Search (BFS) in graph traversal. It begins with an introduction to BFS, highlighting its similarities to tree traversal. The instructor then details the steps to implement BFS using a queue, including marking nodes as visited and handling adjacent nodes. The tutorial concludes with a practical coding example and emphasizes the importance of understanding BFS for various applications.
