  • Q1. Questions related to the work done at my previous company
  • Q2. Find if a given directed graph is cyclic or not
  • Ans. 

    To check if a directed graph is cyclic or not

    • Use Depth First Search (DFS) algorithm to traverse the graph

    • Maintain a visited set to keep track of visited nodes
