Explanation of Solution
Implementation of PrioirtyQueue using Comparator:
//Import the required java package
import java.util.Comparator;
//Define the class Ex24_06
public class Ex24_06 {
//Define the main function
public static void main(String[] args) {
new Ex24_06();
}
//Declare the constructor
public Ex24_06() {
//Create the object for MyPriorityQueue
MyPriorityQueue<String> queue = new
MyPriorityQueue<String>((s1, s2) ->
s1.compareToIgnoreCase(s2));
//Add the elements into queue
queue.enqueue("Macon");
queue.enqueue("Atlanta");
queue.enqueue("Savannah");
queue.enqueue("Augusta");
queue.enqueue("Columbus");
//Check whether the queue size is greater than 0
while (queue.getSize() > 0) {
//Remove the elements from queue
System.out.print(queue.dequeue() + " ");
}
//Create the object for queue1
MyPriorityQueue<String> queue1 = new
MyPriorityQueue<String>((s1, s2) -> s1.length() –
s2.length());
//Add the elements into queue
queue1.enqueue("ABC");
queue1.enqueue("A");
queue1.enqueue("AB");
queue1.enqueue("ABCDE");
queue1.enqueue("ABCD");
System.out.println();
//Check whether the queue1 size is greater than 0
while (queue1.getSize() > 0) {
//Remove the elements from queue

- Profile the performance of the memoized version of the Fibonacci function defined in Project 6. The function should count the number of recursive calls. State its computational complexity using big-O notation, and justify your answer. The fib function header has been modified to include the counter as the second parameter. Define the Counter class, it should have three methods: __init__, increment, and __str__. When an instance of the Counterclass is passed as a parameter, the countproperty of that instance should be incremented based on the number of recursive calls. The __str__ method should return the countproperty's value as a string. Please can you change the solution to this problem here, because this is wrong.
