  • Q5. How many queues will you use to implement a priority queue?
  • Ans. 

    A priority queue can be implemented using a single queue or multiple queues.

    • One approach is to use a single queue and assign priorities to elements using a separate data structure.

    • Another approach is to use multiple queues, each representing a different priority level.

    • For example, if there are three priority levels, three queues can be used to implement the priority queue.
