...Algorithm: In BFS traversal, nodes on the same level are examined first. So, instead of going deep into thegraph, we examine the nodes across the breadth of the graph; before going to the next level. For BFS, we use a queue to pick a node to visit first, and place its unprocessed adjacent nodes in queue. Similarly, pick a node front of queue; if unvisited, we visit the node and again place its neighbors in the queue.
Output of BFS traversal:
A2. Depth First Search (DFS) Traversal:
Contrary to BFS, DFS involves following the path in the graph as deep as possible. If there are no unvisited, adjacent nodes, then we backtrack... A1. Breadth First Search (BFS) Traversal...
