What are the important topics in data structure interview?

Linked List. Dynamic Programming. Sorting And Searching. Tree / Binary Search Tree.

What are the main applications of tree data structure?

Other Applications : Heap is a tree data structure which is implemented using arrays and used to implement priority queues. B-Tree and B+ Tree : They are used to implement indexing in databases. Syntax Tree: Used in Compilers. K-D Tree: A space partitioning tree used to organize points in K dimensional space.

What is BST give a real life example?

A Self-Balancing Binary Search Tree is used to maintain sorted stream of data. For example, suppose we are getting online orders placed and we want to maintain the live data (in RAM) in sorted order of prices. For example, we wish to know number of items purchased at cost below a given cost at any moment.

What is concept of tree data structure?

A tree data structure can be defined recursively as a collection of nodes, where each node is a data structure consisting of a value and a list of references to nodes. The start of the tree is the “root node” and the reference nodes are the “children”. No reference is duplicated and none points to the root.

What are the different types of tree in data structure?

Types of Trees in Data Structure

  • General Tree.
  • Binary Tree.
  • Binary Search Tree.
  • AVL Tree.
  • Red Black Tree.
  • Splay Tree.
  • Treap.
  • B-Tree.

How do you implement a tree?

Binary Tree Implementation

  1. if the new node’s value is lower than the current node’s, go to the left child.
  2. if the new node’s value is greater than the current node’s, go to the right child.
  3. when the current node is null, we’ve reached a leaf node, we insert the new node in that position.

What is tree data structure for coding interview?

The tree data structure is one of the most important and, at the same time, most feared data structures for coding interviews at product-based companies like Amazon, Google, Walmart, and Microsoft. Its extensive applications in software development justify the importance of tree data structure.

Do you find it hard to answer binary trees interview questions?

Often, candidates find it hard to answer questions based on binary trees, binary search trees, and related programs. In this article, we will explore some of the most frequently asked interview questions related to binary trees.

Why do we need different types of data structures?

Different kinds of data structures are suited to different kinds of applications, and some are highly specialized to specific tasks. For example, B-trees are particularly well-suited for the implementation of databases, while compiler implementations usually use hash tables to look up identifiers. (Source: Wiki Page )
