Which of the following traversal methods uses a queue?

Which of the following traversal methods uses a queue?

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 what a queue is. A queue is a data structure that follows the First In, First Out (FIFO) principle.
Step 4: Recognize that Level Order traversal visits nodes level by level, starting from the root.
Step 5: Note that to keep track of which nodes to visit next in Level Order traversal, a queue is used.
Step 6: Conclude that Level Order traversal is the method that uses a queue.
