Question: Which traversal method of a binary tree can be used to retrieve nodes in non-decreasing order?

Options:

  1. Pre-order
  2. Post-order
  3. In-order
  4. Level-order

Correct Answer: In-order

Solution: 

In-order traversal visits the left subtree, the root, and then the right subtree, which results in nodes being retrieved in non-decreasing order for binary search trees.

Questions & Step-by-Step Solutions

Which traversal method of a binary tree can be used to retrieve nodes in non-decreasing order?
  • 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 binary search trees (BST). A binary search tree is a special type of binary tree where the left child is less than the parent node, and the right child is greater than the parent node.
  • Step 3: Know what traversal means. Traversal is the process of visiting each node in the tree in a specific order.
  • Step 4: Identify the different types of traversal methods. The common methods are in-order, pre-order, and post-order traversal.
  • Step 5: Focus on in-order traversal. In in-order traversal, you first visit the left subtree, then the root node, and finally the right subtree.
  • Step 6: Understand the result of in-order traversal in a binary search tree. When you perform in-order traversal on a binary search tree, you will visit the nodes in non-decreasing order (from smallest to largest).
  • Step 7: Conclude that in-order traversal is the method used to retrieve nodes in non-decreasing order for binary search trees.
