# Is BST a binary tree?

## 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

1. All nodes in the left subtree of a node have values less than the node's value.
2. All nodes in the right subtree of a node have values greater than the node's value.
3. 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.
