![]() Push: To add items in a stack we call push operation, which adds the item on the top of the stack.What are different operations available in stack data structure?Īnswer – The different operations in a stack data structure are as follows: There are so many applications of the stack, what are some you can think of? Question 5. As temporary storage in recursive calls.The applications of a stack data structure are: The stack data structure is really useful to keep track of the execution of an application. to get a DVD out of a stack of DVDs we can only access what’s on top, similarly in a stack the access, adding or removing of an element can only be done from top and in a LIFO manner. If you have seen a stack of DVDs or clothes or books you already have a sense of its working i.e. While designing an algorithm it is important to measure the pros and cons of different data structures according to their data insertion, retrieval, and deletion. The performance of tasks a program does depends on the type of data structure used. What is a Data Structure?Īnswer – A data structure is a storage way to organize data. Let’s begin! DSA Interview Questions For Freshers Question 1. And in this article, we will cover the Top 30 most frequently asked DSA interview questions for freshers and experienced. Two types of Data structure and Algorithm questions are asked in interviews: theoretical and coding. Let’s understand more about DSA interview questions. What is the application of the graph data structure?ĭata structure and algorithm is one of the most important topics for efficient algorithm design and problem-solving and this makes DSA one of the most frequent topics for interviews. Differentiate between Breadth First Search (BFS) and Depth First Search (DFS). Discuss the comparison between the Adjacency Matrix and Adjacency List representation of the Graph. What is a Binary Search Tree (BST) data structure What are the different types of traversal in trees? What are the basic terminologies in a Tree data structure? DSA Interview Questions for Experienced.What is the time complexity of basic operations in the HashMap? How are HashMap collisions handled in Java? ![]() Explain the asymptotic analysis of an algorithm. Is Linked List a Linear or Non-linear data structure? What are the different types of Linked Lists? What are different operations available in queue data structure? What are different operations available in stack data structure? What is the difference between Linear and Non-linear data structures? What are the different types of Data Structures?
