Write a program in Java to implement the max-priority queue using max-heap data structure. Implement the max-heap data structure using an integer array of 10 cells. (Do not use Java in-built PriorityQueue class.) [In a max-heap, the root node and the intermediate node vales are always greater than their children.] First, take 10 integer values from the user and insert them in the max-priority queue. Then print the elements of the queue. After that, delete two elements from the queue...

By maintaining the invariant that the elements in the priority
queue are sorted in non-increasing order (that is, the largest item
is first, the smallest is last), you can implement both findMin and
delete Min in constant time. However, insert is expensive. Do the
following:
b. What is the Big-Oh running time for insert?
c. Write an implementation that uses these algorithms.
Algorithm “insert": l/Algorithm insert insert(key, priority) //Check condition if (size == Capacity) //Call the method...

Q2 [ 20 pts]. In computer science, a priority queue is an abstract data type which is like a regular queue data structure, but where additionally each element has a "priority" associated with it. In a priority queue, an element with high priority is served before an element with low priority. If two elements have the same priority, they are served according to the order in which they were enqueued A typical priority queue supports following...

Need some help with some Java studying. Please be as detailed as possible with the answer. - Explain the difference between a mutable and an immutable string, why it’s usually more efficient to use a mutable string, and why using an immutable string make programs safer and more robust. - Explain how Java determines the initial capacity of a StringBuilder object and the new capacity of a StringBuilder object when its current capacity is exceeded.

5. Answer the following.
(a) (5 points) Suppose you are given a maxheap of n unique
numbers. Explain where will the smallest of these n numbers be
located in the maxheap. Explain where will the second largest
number be located on this maxheap. Please be specific.
(b) (5 points) Suppose you are given an array A of n numbers,
where all the elements of the array are already sorted in
decreasing order. Is this a max-heap? Explain.

A priority queue is a collection of items each having a priority. A priority queue supports three fundamental operations. You can ask a priority queue whether it is empty. You can insert an item into the priority queue with a given priority. You can remove the item from the priority queue that has the smallest priority. For example, suppose that you start with an empty priority queue and imagine performing the following steps. Insert item "one" with priority 10. Insert...
