WebMar 5, 2024 · Depth first search explores on a single path in a graph as long as it find undiscovered vertices. When an edge leads to the discovered vertices it backtrack to the previous vertex and explores along the edge where it find undiscovered vertices. Finally it backtracks to the source vertex from where it started. WebApr 10, 2024 · Initialize the adjacency list graph. Read the edges of the graph and add them to the adjacency list. Call the isConnected function to check whether the graph is connected or not, and print the result accordingly. The key idea behind this approach is to use DFS to visit all the vertices in the graph and mark them as visited.
