Solution

Ways to Implement a Priority Queue

The correct answer is:

(A) Arrays, (C) Heap Data Structure, and (D) Linked List

Explanation:

  • Arrays:
    • Unsorted Array: Insertion is O(1), Deletion is O(n).
    • Sorted Array: Insertion is O(n), Deletion is O(1).
  • Heap Data Structure:
    • Binary heaps are commonly used for efficient implementation.
    • Insertion and Deletion take O(log n) time.
  • Linked List:
    • Can be implemented as sorted or unsorted.
    • Efficiency depends on the choice of implementation.

Why not Fibonacci Tree?

Fibonacci trees are not used directly for priority queues. However, Fibonacci heaps (a separate data structure) can implement priority queues efficiently.
