Chapter 8, Problem 8.16PE
(Sort two-dimensional array) Write a method to sort a two-dimensional array using the following header:
public static void sort(int m[] [])
The method performs a primary sort on rows, and a secondary sort on columns. For example, the following array
{{4, 2} ,{1, 7} ,{4, 5},{1, 2} , {1, 1},{4, 1}}
will be sorted to
{{1, 1} , {1, 2} , {1, 7},{4, 1} , {4, 2} , {4, 5}}.

- Indicate true or false for the following statements: Every element in an array has the same type. The array size is fixed after it is declared. The array size declarator must be a constant expression. The array elements are initialized when an array is declared.arrow_forward(Average the major diagonal in a matrix) Write a method that averages all the numbers in the major diagonal in an n * n matrix of double values using the following header: public static double averageMajorDiagonal(double[][] m) Write a test program that reads a 4-by-4 matrix and displays the average of all its elements on the major diagonal.arrow_forward1. (Find the smallest element) Write a method that finds the smallest element in an array of double values using the following header: public static double min(double[] array) Write a test program that prompts the user to enter ten numbers, invokes this method to return the minimum value, and displays the minimum value.arrow_forward
- (Locate the largest element) Write the following function that finds the location of the largest element in a two-dimensional array. void 1ocateLargest(const double a[][4 ], int 1ocation[]) The location is stored in a one-dimensional array location that contains two elements. These two elements indicate the row and column indices of the largest element in the two-dimensional array. Write a test program that prompts the user to enter a 3 × 4 two-dimensional array and displays the location of the largest element in the array.arrow_forwardShift Right k Cells (Use Python) Consider an array named source. Write a method/function named shifRight( source, k) that shifts all the elements of the source array to the right by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] shiftRight(source,3) After calling shiftRight(source,3), printing the array should give the output as: [ 0,0,0,10,20,30 ]arrow_forwardRotate Right k cells (use python) Consider an array named source. Write a method/function named rotateRight( source, k) that rotates all the elements of the source array to the right by 'k' positions.

Example: source=[10,20,30,40,50,60] rotateRight(source,3) After calling rotateRight(source,3), printing the array should give the output as: [ 40, 50, 60, 10, 20, 30]arrow_forward

- please code in python Forbidden concepts: arrays/lists (data structures), recursion, custom classes You have been asked to take a small icon that appears on the screen of a smart telephone and scale it up so it looks bigger on a regular computer screen.The icon will be encoded as characters (x and *) in a 3 x 3 grid as follows: (refer image1 ) Write a program that accepts a positive integer scaling factor and outputs the scaled icon. A scaling factor of k means that each character is replaced by a k X k grid consisting only of that character. Input Specification:The input will be an integer such that 0 < k ≤ 10. Output Specification:The output will be 3k lines, which represent each individual line scaled by a factor of k and repeated k times. A line is scaled by a factor of k by replacing each character in the line with k copies of the character. [refer image2]arrow_forward(Bubble Sort) Implement the bubble sort—another simple, yet inefficient, sorting technique. It’s called bubble sort or sinking sort because smaller values gradually “bubble” their way to the top of the array (i.e., toward the first element) like air bubbles rising in water, while the larger values sink to the bottom (end) of the array. The technique uses nested loops to make several passes through the array. Each pass compares successive overlapping pairs of elements (i.e., elements 0 and 1, 1 and 2, 2 and 3, etc.). If a pair is in increasing order (or the values are equal), the bubble sort leaves the values as they are. If a pair is in decreasing order, the bubble sort swaps their values in the array. The first pass compares the first two elements of the array and swaps them if necessary. It then compares the second and third elements. The end of this pass compares the last two elements in the array and swaps them if necessary. After one pass, the largest element will be in the last…arrow_forward(Algebra: perfect square ) Write a program that prompts the user to enter an integer m and find the smallest integer n such that m * n is a perfect square. (Hint: Store all smallest factors of m into an array list. n is the product of the factors that appear an odd number of times in the array list. For example, consider m = 90, store the factors 2, 3, 3, 5 in an array list. 2 and 5 appear an odd number of times in the array list. So, n is 10.) Sample Run 1 Enter an integer m: 1500 The smallest number n for m x n to be a perfect square is 15 m x n is 22500 Sample Run 2 Enter an integer m: 63 The smallest number n for m x n to be a perfect square is 7 m x n is 441 Class Name: Exercise11_17 Answer is : import java.util.Scanner; public class Squares { public static void main(String[] args) { Scanner scan = new Scanner(System.in); //instantiation of Scanner that will take inputs from the keyboard //the try catch block below is for trapping error with the input try {…arrow_forward
