## What is B+ tree in data structure with example?

A B+ tree is an m-ary tree with a variable but often large number of children per node. A B+ tree consists of a root, internal nodes and leaves. The root may be either a leaf or a node with two or more children….

### How B-tree can be created?

Step 1 – Check whether tree is Empty. Step 2 – If tree is Empty, then create a new node with new key value and insert it into the tree as a root node. Step 3 – If tree is Not Empty, then find the suitable leaf node to which the new key value is added using Binary Search Tree logic.

#### How B-tree is created?

Insertion Operation in B-Tree Step 1 – Check whether tree is Empty. Step 2 – If tree is Empty, then create a new node with new key value and insert it into the tree as a root node. Step 3 – If tree is Not Empty, then find the suitable leaf node to which the new key value is added using Binary Search Tree logic.

**How do you write a B+ tree?**

Insertion in B+ Tree

- Step 1: Insert the new node as a leaf node.
- Step 2: If the leaf doesn’t have required space, split the node and copy the middle node to the next index node.
- Step 3: If the index node doesn’t have required space, split the node and copy the middle element to the next index page.

**What is B-tree key?**

Each internal node of a B-tree will contain a number of keys. The keys act as separation values which divide its subtrees. So, yes, that would be the definition of “keys” for B-trees.

## How do you insert in B-trees?

Insertion Operation

- If the tree is empty, allocate a root node and insert the key.
- Update the allowed number of keys in the node.
- Search the appropriate node for insertion.
- If the node is full, follow the steps below.
- Insert the elements in increasing order.
- Now, there are elements greater than its limit.

### What is a B+ tree?

The B+-tree is a tree structure where every node corresponds to a disk block and which satisfies the following properties: The tree is balanced, i.e., every leaf node has the same depth. An internal node stores a list of keys and a list of pointers.

#### What is a B+ tree index?

The B+ tree is a balanced binary search tree. It follows a multi-level index format. In the B+ tree, leaf nodes denote actual data pointers. B+ tree ensures that all leaf nodes remain at the same height. In the B+ tree, the leaf nodes are linked using a link list.

**Is single node A BST?**

Root-tree: a tree with only one node. Binary tree: a tree in which each node has at most two children (parent, left, and right) Two tree: a binary tree that either is empty or each non-leaf has two children. Heap: a tree where parent node has bigger (smaller) value than children.

**How do you start a B+ tree?**

## What is bubble sorting in C?

Bubble sort in C is a straightforward sorting algorithm that checks and swaps elements if they are not in the intended order. It compares two adjacent elements to find which one is greater or lesser and switches them based on the given condition until the final place of the element is found.

### What is tree size?

The size of a tree is the number of nodes; a leaf by itself has size 1. The height of a tree is the length of the longest path; 0 for a leaf, at least one in any larger tree.

#### Can BST have duplicate values?

Of course yes. One node in BST has two children which are left child and right child. Left child has smaller value than parent node, meanwhile the right child has larger or equal value of parent node. Here is an example of BST with duplicate value.
