Which traversal method is best 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. Traversal methods 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: Visualize level-order traversal. Imagine starting at the root node, then visiting all nodes at the first level (the root), followed by all nodes at the second level (the children of the root), and so on.
Step 5: Conclude that level-order traversal is the best method for printing nodes of a binary tree level by level.
