## Is every BST a binary tree?

Binary Search Tree (BST) on the other hand, is a special form of Binary Tree data structure where each node has a comparable value, and smaller valued children attached to left and larger valued children attached to the right. Thus, **all BST's are Binary Tree** however only some Binary Tree's may be also BST.

## Is B-tree and binary tree same?

Binary tree is the special type of general tree. Unlike B-tree, in a binary tree a node can have at most two nodes….Binary Tree :

S.NO | B-tree | Binary tree |
---|---|---|

5. | B-tree is used in DBMS(code indexing, etc). | While binary tree is used in Huffman coding and Code optimization and many others. |

## What is difference between BST and binary tree?

A Binary search tree is a tree that follows some order to arrange the elements, whereas the binary tree does not follow any order. In a Binary search tree, **the value of the left node must be smaller than the parent node**, and the value of the right node must be greater than the parent node.

## How do you check if a given binary tree is BST or not?

**Check if a binary tree is BST or not**

- All nodes in the left subtree of a node have values less than the node's value.
- All nodes in the right subtree of a node have values greater than the node's value.
- Both left and right subtrees are also binary search trees.

## What is tree and binary tree?

A binary tree is the specialized version of the General tree. A binary tree is **a tree in which each node can have at most two nodes**. In a binary tree, there is a limitation on the degree of a node because the nodes in a binary tree can't have more than two child node(or degree two).

## What is difference between B Tree and B+ tree?

B+ tree is an extension of the B tree. The difference in B+ tree and B tree is that **in B tree the keys and records can be stored as internal as well as leaf nodes** whereas in B+ trees, the records are stored as leaf nodes and the keys are stored only in internal nodes.

## Why are B trees better than BST?

B-trees were designed for platter hard disks, which have a large access time (moving the head into position) after which an entire physical sector is read. Making the B-tree nodes **as large as the sector minimizes the number of access times** and maximizes the useful data out of each read operation.

## What is the difference between BST and heap?

The Heap differs from a **Binary** Search Tree. The BST is an ordered data structure, however, the Heap is not. In computer memory, the heap is usually represented as an array of numbers. … Similarly, the main rule of the Max-Heap is that the subtree under each node contains values less or equal than its root node.

## What is a valid BST?

A valid BST is defined as follows: The left subtree of a node contains only nodes with keys less than the node's key. **The right subtree of a node contains only nodes with keys greater than the node's key**. Both the left and right subtrees must also be binary search trees.

## Can a BST have duplicate values?

In a Binary Search Tree (BST), all keys in left subtree of a key must be smaller and all keys in right subtree must be greater. So a Binary Search Tree by definition has **distinct keys and duplicates in binary search tree are not allowed.**

## Why binary tree is not a tree?

General tree is a tree in which each node can have many children or nodes. Whereas in binary tree, each node can have at most two nodes. … In general tree, a node can have at most n(number of child nodes) nodes. While in binary tree, a node can have at most 2(number of child nodes) nodes.

## What is meant by binary tree?

In computer science, a binary tree is **a tree data structure in which each node has at most two children**, which are referred to as the left child and the right child.

## Is heap a binary tree?

The Heap is **a Complete Binary Tree**. At each level of a Complete Binary Tree, it contains the maximum number of nodes. But, except possibly the last layer, which also must be filled from left to right.
