Questions & Step-by-Step Solutions
Which of the following statements about BFS and DFS is false?
Step 1: Understand what BFS (Breadth-First Search) and DFS (Depth-First Search) are. They are both algorithms used to traverse or search through data structures like trees and graphs.
Step 2: Learn how BFS works. BFS explores all the neighbors of a node before moving on to the next level of nodes. It uses a queue to keep track of the nodes to visit next.
Step 3: Learn how DFS works. DFS explores as far down a branch as possible before backtracking. It uses a stack (or recursion) to keep track of the nodes to visit next.
Step 4: Identify the key difference between BFS and DFS. BFS uses a queue, while DFS uses a stack.
Step 5: Determine which statement about BFS and DFS is false. The statement that says BFS uses a stack is false because BFS actually uses a queue.
