## What are the operations of binary tree?

The main operations in binary tree are: search, insert and delete.

**What operation is allowed in a binary search tree?**

The BST is built on the idea of the binary search algorithm, which allows for fast lookup, insertion and removal of nodes.

**How many common operation are performed in binary tree?**

Three common operations

Explanation: Three common operations are performed in a binary tree- they are insertion, deletion and traversal.

### What is binary tree explain its types and operations on binary trees?

A binary tree is a tree-type non-linear data structure with a maximum of two children for each parent. Every node in a binary tree has a left and right reference along with the data element. The node at the top of the hierarchy of a tree is called the root node. The nodes that hold other sub-nodes are the parent nodes.

**Is tree traversal a linear operation?**

Traversing a tree involves iterating over all nodes in some manner. Because from a given node there is more than one possible next node (it is not a linear data structure), then, assuming sequential computation (not parallel), some nodes must be deferredâ€”stored in some way for later visiting.

**What is a binary search tree ADT explain the insertion operation in binary search tree ADT?**

Binary Search Tree is a node-based binary tree data structure which has the following properties: The left subtree of a node contains only nodes with keys lesser than the node’s key. The right subtree of a node contains only nodes with keys greater than the node’s key.

#### How do you add value to a binary tree?

Algorithm

- Create a new BST node and assign values to it.
- insert(node, key) i) If root == NULL, return the new node to the calling function. ii) if root=>data < key. call the insert function with root=>right and assign the return value in root=>right.
- Finally, return the original root pointer to the calling function.

**How do you insert data into a binary tree?**

Insert (TREE, ITEM)

- Step 1: IF TREE = NULL. Allocate memory for TREE. SET TREE -> DATA = ITEM. SET TREE -> LEFT = TREE -> RIGHT = NULL. ELSE. IF ITEM < TREE -> DATA. Insert(TREE -> LEFT, ITEM) ELSE. Insert(TREE -> RIGHT, ITEM) [END OF IF] [END OF IF]
- Step 2: END.

**Which of the following is an operation on data structure?**

The possible operations on the linear data structure are: Traversal, Insertion, Deletion, Searching, Sorting and Merging.

## How many types of deletion are performed in a binary tree?

There are three situations of deleting a node from binary search tree.

**How many common operations are performed in a binary tree?**

**What are some practical applications of binary search trees?**

Binary Search Tree

### How do you create a binary search tree?

A parent node has,at most,2 child nodes.

**What is an example of an optimal binary search tree?**

When we know the frequency of searching each one of the keys, it is quite easy to compute the expected cost of accessing each node in the tree. An optimal binary search tree is a BST, which has minimal expected cost of locating each node Search time of an element in a BST is O (n), whereas in a Balanced-BST search time is O (log n).

**What are the real time applications of binary search tree?**

Database Indices- When you index a field,it is put in a binary tree for fast retrieval.
