Advanced data structure are a specific type of data structure that is more complicated and detailed than basic data structures. They are used to organize and store data in a more efficient way. There are many different types of advanced data structures, but some of the most common ones include arrays, stacks, queues, and linked lists.
These MCQ questions of Advanced Data Structure are very useful for the preparation of academic and competitive exams like SSC CGL, IBPS (Clerk & PO), BCA, MCA, UPSC, CA, CS, CMA, CPA, CFA, NET, Banking, and other IT & accounts departments.
About Advanced data structures
Advanced data structures are data structures that are more complex and efficient than traditional data structures. They are used to solve complex problems more quickly than traditional data structures. Examples of advanced data structures include B-trees, red-black trees, skip lists, hash tables, and heaps. These data structures are often used in computer science and engineering fields for various applications.
