Question
Which traversal method is used to get the elements of a BST in non-decreasing order?PreorderInorderPostorderLevel order
Solution
The traversal method used to get the elements of a Binary Search Tree (BST) in non-decreasing order is the Inorder traversal method.
Here are the steps for Inorder traversal:
- Traverse the left subtree, i.e., call Inorder(left-subtree)
- Visit the root.
- Traverse the right subtree, i.e., call Inorder(right-subtree)
In a BST, the left subtree has elements less than the root and the right subtree has elements greater than the root. So, traversing the BST in Inorder will give us the elements in non-decreasing order.

Find preorder traversal of height balanced BSTGiven a sorted array. Convert it into a Height balanced Binary Search Tree (BST). Find the preorder traversal of height balanced BST. If there exist many such balanced BST consider the tree whose preorder is lexicographically smallest.Height balanced BST means a binary tree in which the depth of the left subtree and the right subtree of every node never differ by more than 1.Sample input25 1 4 5 7 8 12 14 15 19 20 22 25 26 27 28 29 33 34 37 40 41 42 43 47 48Sample outputoutput=26 12 5 1 4 7 8 19 14 15 22 20 25 37 2
