Question

Please answer the problem in the screenshot. Please use the methods in the second screenshot.

Apply your HeapMax class to solve the following problem:
In a research project your teammate who is responsible for data collection retrieves the
rankings of a set of experiment results, and she chooses to use integers to represent the
success rate of each experiment. The rankings are stored in a n*n matrix where each
row and column are sorted in increasing order. Your project manager wants to know the
ranking of kth most successful experiment. In other words, your task is to find the kth
largest number in the matrix. Please solve the problem to help your teammate.
Please note that it is the kth largest element in the sorted order, not the kth distinct
element./
Example:
matrix =
[
[1, 5, 9],
[10, 11, 13],
[12, 13, 15]
],
k = 2, return 13.
This class is named "HeapMaxApp". The method that solves this problem should be
declared static and named as “kthBiggest", which accepts two required parameters:
public static int kthBiggest(int[][] matr, int k)
You should also create a main method under this class, in which at least two test cases
need to be given to test kthBiggest method by printing necessary information. For
instance, the printed messages of an example are:

Testing of kthBiggest starts.
The given matrix is:
1, 5, 9
10, 11, 13
12, 13, 15
The 4nd biggest element is 12.
Testing of kthBiggest ends.
Note that it is the kth largest element in the sorted order, not the kth distinct element.
Hint: You only need a max heap that always has matr.length elements.
import java.util. *:
public class HeapMaxApp{
public static void main(String[] args) {
// in case if you want to test your solution
}
// return the kth largest element from matr
// you can assume that k is between 1 and matr.length * matr[0].length
public static int kthBiggest(int[]) matr, int k) {
// remove this line
return 0;
}

Using DrawingPanel.java (from chapter 3G), draw a grid for filling in a 4 x 4 square of cell containing integers. For this part of the assignment the values are not important, but you are welcome to use the values shown in the magic square from below. Note that the values in any horizontal row, vertical column or main diagonals add up to 34, in addition to various sub-squares in the larger square also add up to the same value. Requirements: The magic square should be centered in the panel The values in each of the cells should be centered in that cell (both horizontally and vertically). You can assume the values will be <= 99 (i.e., at most 2 digits). For this part of the assignment, you can hard-code the values; you will store them in a 2-dimensional array (from chapter 7) when implementing Part B of the assignment. The title "CSC 142 Magic Square" is centered horizontally in the panel and at y = 50 You are free to choose the colors, fonts, font sizes and effects. This is what I used…
