What data structure is typically used to implement BFS?
Step 1: Understand what BFS (Breadth-First Search) is. It is an algorithm used to explore nodes and edges of a graph.
Step 2: Know that BFS explores all neighbors of a node before moving to the next level of nodes.
Step 3: Realize that to keep track of which nodes to explore next, we need a way to store them.
Step 4: Learn that a queue is a data structure that works like a line, where the first item added is the first one to be removed (FIFO - First In, First Out).
Step 5: Conclude that BFS uses a queue to manage the order of nodes to be explored, ensuring they are processed in the order they are discovered.
