# What is inorder traversal of BST?

## What is inorder traversal example?

Example of inorder traversal we start recursive call from 30(root) then move to 20 (20 also have sub tree so apply in order on it),15 and 5. 5 have no child . so print 5 then move to it's parent node which is 15 print and then move to 15's right node which is 18. … now recursively traverse to right subtree of root node .

## What is inorder traversal algorithm?

What Is InOrder Traversal Algorithm? The InOrder traversal is one of the three popular ways to traverse a binary tree data structure, the other two being the preOrder and postOrder. During the in-order traversal algorithm, the left subtree is explored first, followed by root, and finally nodes on the right subtree.

## What is inorder traversal used for?

In-order traversal is very commonly used on binary search trees because it returns values from the underlying set in order, according to the comparator that set up the binary search tree. Post-order traversal while deleting or freeing nodes and values can delete or free an entire binary tree.

## Is BST using inorder traversal?

Basically Inorder traversal for a BST gives us the elements in ascending order. So in your code, during the traversal the previous node is saved to compare it with current node. When compared, the current node's data should be strictly greater than previous node's data as traversal gives the ascending order.

## How do you find the inorder traversal?

Inorder(root)

1. Traverse the left sub-tree, (recursively call inorder(root -> left).
2. Visit and print the root node.
3. Traverse the right sub-tree, (recursively call inorder(root -> right).

## What is BST in data structure?

In computer science, a binary search tree (BST), also called an ordered or sorted binary tree, is a rooted binary tree data structure whose internal nodes each store a key greater than all the keys in the node's left subtree and less than those in its right subtree.

## What approach is used for inorder traversal?

There are two approaches used for the inorder traversal: Inorder traversal using Recursion. Inorder traversal using an Iterative method.

## What is inorder traversal in data structure?

An inorder traversal is a traversal technique that follows the policy, i.e., Left Root Right. Here, Left Root Right means that the left subtree of the root node is traversed first, then the root node, and then the right subtree of the root node is traversed.

## How do you make BST from inorder traversal?

Construct Special Binary Tree from given Inorder traversal

1. Find index of the maximum element in array.
2. Create a new tree node 'root' with the data as the maximum value found in step 1.
3. Call buildTree for elements before the maximum element and make the built tree as left subtree of 'root'.

There are two approaches used for the inorder traversal: Inorder traversal using Recursion. Inorder traversal using an Iterative method.

## What is inorder in data structure?

Unlike linear data structures (Array, Linked List, Queues, Stacks, etc) which have only one logical way to traverse them, trees can be traversed in different ways. … In the case of binary search trees (BST), Inorder traversal gives nodes in non-decreasing order.

## What is BST explain the operations of BST?

A Binary Search Tree (BST) is a tree in which all the nodes follow the below-mentioned properties − The value of the key of the left sub-tree is less than the value of its parent (root) node's key. The value of the key of the right sub-tree is greater than or equal to the value of its parent (root) node's key.

## How do you make a BST?

Insertion in BST

1. If the data of the root node is greater, and if a left subtree exists, then repeat step 1 with root = root of left subtree. Else, insert element as left child of current root.
2. If the data of the root node is greater, and if a right subtree exists, then repeat step 2 with root = root of right subtree.

## How do you inorder a traversal tree?

Construct Special Binary Tree from given Inorder traversal

1. Find index of the maximum element in array.
2. Create a new tree node 'root' with the data as the maximum value found in step 1.
3. Call buildTree for elements before the maximum element and make the built tree as left subtree of 'root'.
