## What is BST with example?

**Binary Search Tree** is a special kind of binary tree in which nodes are arranged in a specific order. In a binary search tree (BST), each node contains- Only smaller values in its left sub tree. Only larger values in its right sub tree.

## What is BST used for?

A BST **supports operations like search, insert, delete, floor, ceil, greater, smaller, etc in O(h) time where h is height of the BST**. To keep height less, self balancing BSTs (like AVL and Red Black Trees) are used in practice. These Self-Balancing BSTs maintain the height as O(Log n).

## Which data structure is used in BST?

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.

## What is BST theory?

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.

## What is BST explain its traversal?

Often we wish to process a binary tree by “visiting” each of its nodes, each time performing a specific action such as printing the contents of the node. **Any process for visiting all of the nodes in some order** is called a traversal.

## What is the current BST?

British Summer Time is 1 hour ahead from the UTC universal time. BST current date is **23rd Tuesday November 2021**. Current time in BST (BST)….British Summer Time Date and Time Now in Various Formats.

Date Time Format | BST Date Time Now |

## What is DFS graph?

**Depth-first search** (DFS) is an algorithm for traversing or searching tree or graph data structures. The algorithm starts at the root node (selecting some arbitrary node as the root node in the case of a graph) and explores as far as possible along each branch before backtracking.

## Which of the following traversal is sufficient to BST?

GATE Question To construct BST **either preorder or postorder** is sufficient because inorder is always sorted for BST.

## What is BST and GMT?

The period when the clocks are 1 hour ahead is called **British Summer Time (BST)**. There's more daylight in the evenings and less in the mornings (sometimes called Daylight Saving Time). When the clocks go back, the UK is on Greenwich Mean Time (GMT).

## What BST means?

British Summer Time

During **British Summer Time** (BST), civil time in the United Kingdom is advanced one hour forward of Greenwich Mean Time (GMT), in effect changing the time zone from UTC+00:00 to UTC+01:00, so that mornings have one hour less daylight, and evenings one hour more.

## How do you represent BST in an array?

In array representation of a binary tree, we use one-dimensional array (1-D Array) to represent a binary tree. Consider the above example of a binary tree and it is represented as follows… To represent a binary tree of depth 'n' using array representation, we need one dimensional array with a **maximum size** of 2n + 1.
