Questions & Step-by-Step Solutions
Which traversal method is used to print the nodes of a binary tree level by level?
Step 1: Understand what a binary tree is. A binary tree is a data 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. Tree traversal is the process of visiting all the nodes in a tree data structure in a specific order.
Step 3: Identify the different types of tree traversal methods. Common methods include in-order, pre-order, post-order, and level-order.
Step 4: 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 5: Conclude that level-order traversal is the correct method to print the nodes of a binary tree level by level.
