A self – balancing binary search tree can be used to implement ________

(a) Priority queue

(b) Hash table

(c) Heap sort

(d) Priority queue and Heap sort

The above asked question is from Binary Trees in section Binary Trees of Data Structures & Algorithms I

I have been asked this question in an interview for job.

Answer 1

Right choice is (a) Priority queue

Explanation: Self-balancing binary search trees can be used to construct and maintain ordered lists, to achieve the optimal worst case performance. So, self – balancing binary search tree can be used to implement a priority queue, which is ordered list.
