Answer :
b. a sorted array.
Explanation :
Using an Sorted Array
The findMax operation will be faster as compared to unsorted array as either the array is dorted in descending or in ascending order the time complexity will be O(1). Also if we use an array to store the values in the priority queue, we can either store the values in sorted order (which will make the insert operation slow, and the deleteMax operation fast), or in arbitrary order (which will make the insert operation fast, and the deleteMax operation slow). Note also that we'll need a field to keep track of the number of values

In class, we discussed the priority queue (PQ) ADT implemented using min-heap. In a min-heap, the element of the heap with the smallest key is the root of the binary tree. On the other hand, a max-heap has as root the element with the biggest key, and the relationship between the keys of a node and its parent is reversed of that of a min-heap. We also discussed an array-based implementation of heaps. In this assignment, your task is to...

5. Consider a priority queue of strings with an integer priority. The queue us implemented as a min heap using a 0-based array of size 8 with methods push(entry, priority) and pop(). Determine the priority queue contents, represented both as an array and as a tree, at the points indicated below during the following operations on the ADT. Write down the queue contents after the operation on the given line is executed. 1. priority_queue<string, int> pq; 2. pq.push("start", 10); 3....

Consider the following functions that implement the dequeue operation for a priority queue that is implemented with a heap. int[] pQueue; int length; int dequeue() { int node = 1; int value = pQueue[--length]; int maxValue = pQueue[node]; int location = sift(node * 2, value); pQueue[location] = value; return maxValue; } int sift(int node, int value) { if (node <= length) { if (node < length && pQueue[node] < pQueue[node + 1]) node++; if (value < pQueue[node]) { pQueue[node /...
