Basic data structures for interview11/19/2023 ![]() This means you do not need to re-declare memory if an array grows too big as it doesn’t have to be close to each other to work. In this structure, elements of the array are interlinked instead of being indexed as in an array. Linked lists are the basis for implementing queues and stacks, and are quite crucial for creating graphs. That is, the interviewer may ask how you would implement a queue using a stack or vice versa. Essentially, a stack is a data structure where new elements are put on top and are normally retrieved from the top of the list, and a queue is a structure where new elements are placed in the bottom and are retrieved from the top as well.Īpart from talking about the implementation of these two data structures in practice, you will have to answer questions about implementing one as the other. Stacks and queuesīoth stack and queue are linear data structures, but the major difference between them is that stack uses the Last In, First Out method while queue uses the First In, First Out method. You’ll need to work on your math skills to answer any of these. This type of question heavily relies on maths, like finding the longest consecutive sequence of numbers in an array or a subarray with the largest sum. Typically, you’ll need to provide an answer to a practical problem and write some code to execute your solution.Ī good example of this would be finding the second largest number in the array or deleting duplicate entries.Īpart from the duplicate entry questions, there’s another one that often appears on data structure interviews. Now, when you’re done with the basic questions, you’ll have to answer something more advanced. ![]() Most popular languages today are zero-based, while some like Cobol and Fortran are 1-based. You may also need to provide a couple of examples of languages with zero and 1-based indexing. You may need to explain how arrays work and how implementing arrays would work in different languages. Most interviews would start by asking basic questions. Hence, knowing everything you can about arrays is crucial to let your employers know you’re good at data management. Heaps, linked lists, and others are formed based on arrays. ![]() ArraysĪn array is one of the most basic data structures. Here are the 6 most popular data structures that will help you ace your next coding interview. While you can think your way through a difficult code implementation question, when it comes to data structures, the only thing that’s going to save you is knowledge. You can’t look for answers like you’d typically do if you’re at loss when solving a programming problem. However, proving your worth in an interview by showcasing impeccable programming skills may be challenging.Īpart from the pressure that you must feel when your employment depends on a 45-minute talk, there’s one more thing that makes beginner programmers uneasy. As a beginner in programming, you may be able to work on your projects confidently.
