Questions & Step-by-Step Solutions
Which of the following statements is true regarding BFS?
Step 1: Understand what BFS stands for. BFS means Breadth-First Search, which is a way to explore or traverse a graph or tree.
Step 2: Learn about the data structure used in BFS. BFS uses a queue, which is a collection where you add items to the back and remove items from the front.
Step 3: Know how BFS works. It starts at a specific node (the root or starting point) and explores all its neighbors (connected nodes) first.
Step 4: Realize the order of exploration. After exploring all neighbors at the current level (depth), BFS then moves on to the next level of neighbors.
Step 5: Conclude that BFS is effective for finding the shortest path in unweighted graphs because it explores all possibilities at the current depth before going deeper.
