What data structure does BFS use for traversal?
Queue
What is the purpose of using a boolean visited array in BFS for a graph?
To keep track of the nodes that have been visited
How is BFS for a graph different from BFS for a tree?
BFS for a graph may contain cycles, while BFS for a tree cannot
What is the purpose of using a boolean visited array in BFS for a graph?
To mark the visited vertices and avoid processing a node more than once
What data structure is used by BFS for traversal?
Queue
What is the difference between BFS for a graph and BFS for a tree?
BFS for a graph may visit the same node more than once due to cycles, while BFS for a tree visits each node only once
