Questions & Step-by-Step Solutions
Which of the following is true about BFS?
Steps
Concepts
Step 1: Understand what BFS stands for. BFS means Breadth-First Search, which is a way to explore graphs.
Step 2: Know that BFS starts at a specific node (called the root) and explores all its neighbors first.
Step 3: After exploring all neighbors of the current node, BFS moves on to the neighbors of those neighbors, going one level deeper.
Step 4: This process continues until all nodes at the current depth level are explored before moving to the next level.
Step 5: In unweighted graphs, BFS guarantees that the first time it reaches a node, it has found the shortest path to that node.
