Which of the following operations is not typically supported by a priority queue?*1 pointInsertionDeletionModication of priorityRandom Access

To determine which operation is not typically supported by a priority queue, let's analyze each option:

1. Insertion: This operation is essential for a priority queue as it allows you to add elements with an associated priority.

2. Deletion: Priority queues typically support deletion, particularly a deletion of the highest (or lowest) priority element. This operation is fundamental for the priority queue’s behavior.

3. Modification of priority: While not universally supported by all priority queue implementations, many priority queues allow you to change the priority of an existing element, although this can be less efficient in some implementations.

4. Random Access: This operation is not typically supported in a priority queue. Priority queues do not maintain elements in an order that allows for direct index-based access. Instead, elements are accessed in priority order, which does not enable random access.

Final Answer

The operation that is not typically supported by a priority queue is Random Access.
