Priority Queues1.5. Insert and Delete Operations in 2D Structure

Try these first

1. 1.

   What operation is used to add a new job to a priority queue?

   Hint

   Think about how we add elements to any list or queue.

2. 2.

   What is 'Delete Max' in a priority queue?

   Hint

   Consider what priorities control the order of job execution.

3. 3.

   What is the primary function of a priority queue?

   • To sort elements
   • To manage tasks based on priority
   • To store elements in FIFO order

   Hint

   Consider the purpose of the term 'priority'.

4. 4.

   True or False: In a sorted list implementation of a priority queue, insertion is faster than deletion.

   • True
   • False

   Hint

   Think about how sorted order affects where you put new elements.

5. 5.

   Design a priority queue that can handle 1000 jobs using a two-dimensional array and calculate the maximum and minimum insert/deletion times.

   Hint

   Apply the principles of sorting and organization we discussed.

6. 6.

   Explain how shifting to a binary heap could further optimize a system that uses a two-dimensional array for priority management.

   Hint

   Consider how a balanced tree structure changes the complexity of these operations.
