![]() ![]() It's a recursive data structure with a top-level pointer. It is the most basic data structure in which a data element can be accessed at random using its index number alone.Ī stack is an ordered list in which only one end, called the top, can be used for insertion and deletion. Graphs and Trees are two examples.Īrrays are collections of comparable sorts of data kept in close proximity in memory. Non-Linear: If the traversal of nodes is nonlinear, the data structure is said to be non-linear. Linear: If the elements of a data structure form a sequence or a linear list, it is said to be linear. What are the differences between linear and non-linear data structures? It also establishes relationships and forms algorithms by defining how distinct types of data relate to one another.Ģ. The Data Structure describes how data is organized (stored), altered, and accessed. What is the definition of a data structure? Here are some of the most common data structure interview questions and answers, along with their replies:ġ. Data structures might be the subject of a few or many questions in every programming language interview. Knowing how to think in terms of data structures and algorithms will help you stand out from the crowd. Just keep in mind that data structure interviewers aren't attempting to fool you, and they don't expect perfection, but it is their chance to assess your understanding before investing in your job.Īny programming job interview, especially one for a Data Science or Java-based post, should include data structures and algorithm questions. You might be curious about the types of questions you'll be asked during your next data structure interview.
