Write a program to declare a matrix A[][] of order (M × N) where ‘M’ is the number of rows and ‘N’ is the number of columns such that the values of both ‘M’ and ‘N’ must be greater than 2 and less than 10. Allow the user to input integers into this matrix.
Perform the following tasks on the matrix:
(a) Display the original matrix.
(b) Sort each row of the matrix in ascending order using any standard sorting technique.
(c) Display the changed matrix after sorting each row.
Test your program for the following data and some random data:
Example 1:
INPUT:
M = 4
N = 3
ENTER ELEMENTS OF MATRIX
11 | -2 | 3 |
5 | 16 | 7 |
9 | 0 | 4 |
3 | 1 | 8 |
OUTPUT:
ORIGINAL MATRIX
11 | -2 | 3 |
5 | 16 | 7 |
9 | 0 | 4 |
3 | 1 | 8 |
MATRIX AFTER SORTING ROWS
-2 | 3 | 11 |
5 | 7 | 16 |
0 | 4 | 9 |
1 | 3 | 8 |
Example 2:
INPUT:
M = 3
N = 3
ENTER ELEMENTS OF MATRIX
22 | 5 | 19 |
7 | 36 | 12 |
9 | 13 | 6 |
OUTPUT:
ORIGINAL MATRIX
22 | 5 | 19 |
7 | 36 | 12 |
9 | 13 | 6 |
MATRIX AFTER SORTING ROWS
5 | 19 | 22 |
7 | 12 | 36 |
6 | 9 | 13 |
Example 3:
INPUT:
M = 11
N = 5
OUTPUT:
MATRIX SIZE OUT OF RANGE
import java.util.Scanner;
class Sort{
public static void main(String[] args){
Scanner in = new Scanner(System.in);
System.out.print("M = ");
int m = Integer.parseInt(in.nextLine());
System.out.print("N = ");
int n = Integer.parseInt(in.nextLine());
if(m < 3 || m > 9 || n < 3 || n > 9){
System.out.println("MATRIX SIZE OUT OF RANGE");
return;
}
int a[][] = new int[m][n];
System.out.println("ENTER ELEMENTS OF MATRIX");
for(int i = 0; i < m; i++){
for(int j = 0; j < n; j++){
a[i][j] = Integer.parseInt(in.nextLine());
}
}
System.out.println("ORIGINAL MATRIX");
for(int i = 0; i < m; i++){
for(int j = 0; j < n; j++)
System.out.print(a[i][j] + "\t");
System.out.println();
}
for(int i = 0; i < m; i++){
for(int j = 0; j < n; j++){
for(int k = 0; k < n - 1 - j; k++){
if(a[i][k] > a[i][k + 1]){
int temp = a[i][k];
a[i][k] = a[i][k + 1];
a[i][k + 1] = temp;
}
}
}
}
System.out.println("MATRIX AFTER SORTING ROWS");
for(int i = 0; i < m; i++){
for(int j = 0; j < n; j++)
System.out.print(a[i][j] + "\t");
System.out.println();
}
}
