Q2. 
BFS Traversal in a Graph
Given an undirected and disconnected graph G(V, E) where V vertices are numbered from 0 to V-1, and E represents edges, your task is to output the BFS traversal starting from the ...read more
Ans. 
BFS traversal in a disconnected graph starting from vertex 0.
• Use BFS algorithm to traverse the graph starting from vertex 0.

• Explore neighbor nodes first before moving to the next level neighbors.

• Consider bidirectional edges in an undirected graph.

• Output the BFS traversal sequence for each test case in a separate line.

• Ensure the BFS path starts from vertex 0 and print connected nodes in numerical sort order.

Sort a given stack in ascending order using only push and pop operations with the help of an additional stack.
• Use one additional stack to assist in sorting the elements.

• Pop elements from the input stack and push them onto the auxiliary stack in sorted order.

• Keep track of the current minimum element to maintain ascending order.
