Questions & Step-by-Step Solutions
Which of the following statements about BFS is true?
Step 1: Understand what BFS stands for. BFS means Breadth-First Search, which is a way to explore nodes in a graph or tree.
Step 2: Know that BFS starts at a specific node, called the 'root' or 'starting node'.
Step 3: Realize that BFS explores all the neighboring nodes at the current depth before moving on to nodes at the next depth level.
Step 4: Visualize this process: Imagine you are at a level in a building. You check all the rooms on that floor (current depth) before going up to the next floor (next depth).
Step 5: Conclude that the statement 'BFS explores nodes level by level, ensuring that all nodes at the present depth are explored before moving deeper' is true.
