Reachability in an undirected graph: O(V+E) algorithm using BFS/DFS.
Analyze the reachability in an undirected graph: o(v+e) algorithm using bfs/dfs..
Examples
Input:"test_input_1"
Output:"output_1"
Input:"test_input_2"
Output:"output_2"
Hints
Start by initializing a visited array to keep track of nodes that have been explored during traversal.
Use a queue (for BFS) or stack (for DFS) to systematically explore all nodes reachable from a starting node, ensuring no node is revisited.
After traversal, analyze the visited array to determine which nodes are reachable from the starting node, considering the graph's undirected nature and potential disconnected components.
