Questions & Step-by-Step Solutions
Which traversal method uses a queue data structure?
Step 1: Understand what a traversal method is. It is a way to visit all the nodes in a tree or graph.
Step 2: Learn about different traversal methods. Common methods include in-order, pre-order, post-order, and level-order.
Step 3: Identify the level-order traversal method. This method visits all nodes at the current level before moving to the next level.
Step 4: Recognize that level-order traversal uses a queue. A queue is a data structure that follows the First In, First Out (FIFO) principle.
Step 5: Understand how the queue works in level-order traversal. Nodes are added to the queue as they are visited, and nodes are removed from the queue to visit their children.
