Which traversal method of a binary tree will give the 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 of a node contains only nodes with values less than the node's value, and the right child contains only nodes with values greater than the node's value.
Step 3: Know what traversal means. Traversal is the process of visiting all the nodes in a tree in a specific order.
Step 4: Identify the types of tree 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 visit the left child, then the node itself, and finally the right child.
Step 6: Understand how in-order traversal works in a binary search tree. When you perform in-order traversal on a BST, you will visit the nodes in ascending order because of the properties of the BST.
Step 7: Conclude that in-order traversal of a binary search tree will give you the nodes in non-decreasing order.
