Write a Program to  Construct an array of 100 elements containing the numbers 1 through 100 for which shellsort, with the increments 1 4 13 40, uses as large a number of compares as you can find.

Write a Java application for a grade book using arrays: Create an array to store 20 test grades, random numbers between 0-100, inclusive.  Print these 20 grades Calculate and print the average grade Calculate and print the highest and lowest grades Complete BMI arrays template BMI.java   Use two int arrays to store n numbers from user input, called height[] and weight[].  "The BMI is defined as the body mass divided by the square of the body height" Calculate BMIs and store values into a double array called bmi[].    Write a method to print an array, use an enhanced for loop in the print method.  Print the BMIs by invoking the print method.  import java.util.Scanner;public class BMI{public static void main(String[] args){Scanner key = new Scanner (System.in);int num = // use Scanner object to get an integer// declare an int array for heightint[] height = new int[num];// declare an int array for weight below...// declare an array for BMI array...for ( ){ // iterate all array…

Write a program that will rearrange and print an array of positive integers entered by the user. The program must arrange the elements in such a way, first element should be maximum value, second minimum value, third second maximum value, fourth second minimum value, fifth third maximum and so on.

The Lo Shu Magic Square is a grid with 3 rows and 3 columns shown below.             The Lo Shu Magic Square has the following properties: The grid contains the numbers 1 – 9 exactly The sum of each row, each column and each diagonal all add up to the same number. This is shown below: Write a program that simulates a magic square using 3 one dimensional parallel arrays of integer type. Do not use two-dimensional array. Each one the arrays corresponds to a row of the magic square. The program asks the user to enter the values of the magic square row by row and informs the user if the grid is a magic square or not. Processing Requirements - c++ Use the following template to start your project: #include<iostream> using namespace std;   // Global constants const int ROWS = 3;  // The number of rows in the array const int COLS = 3;  // The number of columns in the array const int MIN = 1;  // The value of the smallest number const int MAX = 9;  // The value of the largest number //…
