Which of the following is NOT a valid implementation of a priority queue?
Step 1: Understand what a priority queue is. A priority queue is a data structure where each element has a priority. Elements with higher priority are served before those with lower priority.
Step 2: Learn about common implementations of a priority queue. The most common implementations are heaps (like binary heaps) because they allow for efficient insertion and removal of the highest priority element.
Step 3: Consider other data structures that can be used for a priority queue. A binary search tree (BST) can be used, but it is not as efficient as a heap for this purpose.
Step 4: Identify the question's focus. The question asks which option is NOT a valid implementation of a priority queue.
Step 5: Conclude that while a binary search tree can technically be used to implement a priority queue, it is not a typical or efficient choice compared to heaps.
