Which traversal method is best suited for printing the nodes of a binary tree level by level?
Step 1: Understand what a binary tree is. A binary tree is a structure where each node has at most two children, referred to as the left child and the right child.
Step 2: Learn about tree traversal methods. These are ways to visit all the nodes in a tree. Common methods include in-order, pre-order, post-order, and level-order.
Step 3: Focus on level-order traversal. This method visits all the nodes at the present depth level before moving on to nodes at the next depth level.
Step 4: Realize that level-order traversal uses a queue to keep track of nodes. It starts from the root, adds it to the queue, and then processes each node by adding its children to the queue.
Step 5: Conclude that level-order traversal is the best method for printing nodes of a binary tree level by level because it processes nodes in the order of their levels.
