Are you searching for Data Structures job? A Data Structure in computer science is a kind of managing and storing data in order to access it efficiently. Implementing data structures requires writing a set of procedures that are used in creating and managing instances of that structure.

## Top 50 Data Structures Interview Questions

Data Structure Viva Questions. What is a Register? Ans- A register is a small amount of memory within the CPU that is used to temporarily store instructions and data. Ans-abstract Q3. What are the different Abstract Data Type Groups? A Short B Int C float D long Explanation: The integer abstract data type group consists of four abstract data types used to reserve memory to store whole numbers: byte, short, int , and long Q5.

What pointer type is used to implement the heterogeneous linked list in C? The answer is the void pointer. The heterogeneous linked list contains different data types in it's nodes and we need a link, pointer, to connect them.

Since we can't use ordinary pointers for this, we use the void pointer. Void pointer is a generic pointer type, and capable of storing pointer to any type. What is the minimum number of queues needed to implement the priority queue? One queue is used for the actual storing of data, and the other one is used for storing the priorities.

Which data structure is used to perform recursion? The answer is Stack. Therefore, it knows to whom it should return when the function has to return. On the other hand, recursion makes use of the system stack for storing the return addresses of the function calls.

Every recursive function has its equivalent iterative non-recursive function. Even when such equivalent iterative procedures are written explicit, stack is to be used. What are some of the applications for the tree data structure? Which data strucutres algorithm used in solving the eight Queens problem? Backtracking Q In an AVL tree, at what condition the balancing is to be done?

If the "pivotal value", or the "height factor", is greater than one or less than minus one. There are 8, 15, 13, and 14 nodes in four different trees. Which one of them can form a full binary tree? The answer is the tree with 15 nodes. By the method of elimination: Full binary trees contain odd number of nodes, so there cannot be full binary trees with 8 or 14 nodes. Moreover, with 13 nodes you can form a complete binary tree but not a full binary tree. Thus, the correct answer is Email This BlogThis!

A data structure can be any organization, management, and storage format of data that allows efficient access and modification. It is a collection of data values, relationships amongst them, and the various functions or operations that can be applied to the data. Data structures are a foundational concept of programming which is immensely utilized in algorithm design. Hence, it is important for any programmer, irrespective of the programming language , to have a good understanding of data structures. Any programming language interview can have a few or many questions based on data structures.

A list of most frequently asked Data Structure interview questions and answers are given below. The data structure is a way that specifies how to organize and manipulate the data. It also defines the relationship between them. Data Structures are the central part of many computer science algorithms as they enable the programmers to handle the data in an efficient way.

Download PDF 1 Explain what is an algorithm in computing? An algorithm is a well-defined computational procedure that take some value as input and generate some value as output. Quick Sort algorithm has the ability to sort list or queries quickly. It is based on the principle of partition exchange sort or Divide and conquer.

Knowing how to store data and manipulate the same easily will give programmers an edge over the competition. Data structures are used across the world in almost every aspect of data storage one can think of. This means that the questions you might find in an interview can be challenging. Data Structures are extremely integral in a variety of fields. Companies across the globe invest in millions of dollars to fully integrate their data handling systems with efficient data structures rather than conventional methods.

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. Source: Wiki Page.
