Breadth‑First Search (BFS) Explained | 11th Computer | Algorithms & Problem Solving (Chapter 3)”

Welcome to our deep dive into Breadth‑First Search (BFS), one of the key graph traversal algorithms in your 11th-grade Computer Chapter 3: Algorithms & Problem Solving!

In this lesson, you'll learn:

What BFS is: A method of exploring a graph level-by-level starting from a source node—visiting all neighboring nodes before moving deeper.

How it works: Step-by-step demonstration using a queue (FIFO) to ensure nodes are processed in the order they're discovered—perfect for finding the shortest path in un weighted graphs.

Why it matters: We'll compare BFS with Depth-First Search (DFS), highlighting when BFS is more suitable—such as in shortest-path problems or scenarios where all nodes at the same depth need exploration.

Algorithm complexity: Understanding its time complexity of O(V + E) and space complexity of O(V) (where V = number of vertices, E = number of edges)

Real-world uses: BFS powers GPS path finding, social network searches, web crawlers, and more.
