👉 Welcome to Day 37 of 100 Days Programming Way Challenges!

Today we learn about Breadth First Search (BFS) – one of the most fundamental graph traversal algorithms.

✅ What is BFS?
BFS explores a graph level by level.
It starts from a source node, visits all its neighbors, then moves to the next level.
Implemented using a Queue (FIFO).

✅ Why BFS?
Used in shortest path problems (unweighted graphs).
Important for social networking suggestions, crawling web pages, GPS maps, AI pathfinding.

✅ Python Implementation:
Using Adjacency List representation
BFS using Queue (collections.deque)
