Top 35 Data Structure Interview Questions in 2021

As per my experience good interviewers hardly plan to ask any particular question during your interview, normally questions start with some basic concept of the subject and later they continue based on further discussion and what you answer:. A data structure may contain different type of data items. Data structure availability may vary by programming languages. Commonly available data structures are list, arrays, stack, queues, graph, tree etc. Algorithm is a step by step procedure, which defines a set of instructions to be executed in certain order to get the desired output.

What are the major data structures used in the following areas : Rdbms, network data model and Hierarchical data model. If you are using c language to implement the heterogeneous linked list, What pointer type will you use? It is not possible to use ordinary pointers for this. Void pointer is capable of storing pointer to any type as it is a generic pointer type. Recursion makes use of system stack for storing the return addresses of the function calls. What are the notations used in evaluation of arithmetic expressions using prefix and postfix forms?

Algorithms. Java Algorithm And Data Structure Interview Questions and Programs Time complexity of the solution is O(n) as it traverses the tree only once.


300+ TOP DATA STRUCTURES Interview Questions and Answers pdf

Coding interviews are comprised mainly of data structure and algorithm-based questions as well as some of the logical questions such as, How do you swap two integers without using a temporary variable? There are a lot of computer science graduates and programmers applying for programming, coding, and software development roles at startups like Uber and Netflix. Once you have gone through these questions, you should feel confident enough to attend any telephonic or face-to-face interviews. Without any further ado, here is my list of some of the most frequently asked coding interview questions from programming job interviews :.

What is a Data Structure? A data structure is a way of organizing the data so that the data can be used efficiently. 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.

Data Structure Interview Questions

It seeks to find ways to make data access more efficient. When dealing with the data structure, we not only focus on one piece of data but the different set of data and how they can relate to one another in an organized manner. The key difference between both the data structure is the memory area that is being accessed. When dealing with the structure that resides the main memory of the computer system, this is referred to as storage structure. When dealing with an auxiliary structure, we refer to it as file structures.

So I am consolidating a list of java coding interview questions to create an index post. I will keep adding links to this post whenever I will add new java coding interview question. If you want to practice and improve data structure and algorithm programs, this post will be very helpful to you. I will recommend you to try it yourself first and then check the solution. For example: Angel and Angle are anagrams There are few ways to check if Strings are anagrams. Some of them are:. Solution: You can use try catch block for catching StringIndexOutOfBoundException and when this exception aries, you can simply return i Index at which you will get the exception Please refer to complete solution at find length of String without inbuilt methods.

Notes on Data Structures and Programming Techniques. Introduction to Data Structure. Concise Notes on Data Structures and Algorithms.

Proper preparation is always advised. Data structures and algorithm questions are an important part of any programming job interview, especially one for Data Science and Java-based role. Sound knowledge of data structures and algorithms will help you stand apart from the herd.

Great post Javin! Really helpful. I was recently asked following questions in interviews. I have found answers via Google search, but it would be great to know your comments on these questions.
