Q4. What is bfs and dfs
Ans. 
BFS (Breadth First Search) and DFS (Depth First Search) are algorithms used in graph traversal to visit all the nodes in a graph.
• BFS explores all the neighbor nodes at the present depth prior to moving on to the nodes at the next depth level.

• DFS explores as far as possible along each branch before backtracking.

• BFS uses a queue data structure, while DFS uses a stack or recursion.

• Example: BFS can be used to find the shor...read more
