Q1. Check whether a given graph is cyclic
Ans. 
To check if a graph is cyclic, use depth-first search to detect back edges.
• Perform a depth-first search on the graph and keep track of visited nodes and parent nodes.

• If a visited node is encountered with a parent different from the current node, then the graph contains a cycle.

• Example: For a graph with edges (A, B), (B, C), (C, A), the graph is cyclic.
