Write a program to declare a square matrix A[][] of order M × M where ‘M’ is the number of rows and the number of columns, such that M must be greater than 2 and less than 10.

Accept the value of M as user input. Display an appropriate message for an invalid input. Allow the user to input integers into this matrix. Perform the following tasks:
(a) Display the original matrix.
(b) Check if the given matrix is said to be symmetric or not. A square matrix is said to be symmetric, if the element of the i^th row and j^th column is equal to the element of the j^th row and i^th column.
(c) Find the sum of the elements of left diagonal and the sum of the elements of right diagonal of the matrix and display them.

Example 1
INPUT:
M = 3
Enter elements of the matrix:
1 2 3
2 4 5
3 5 6
OUTPUT:
ORIGINAL MATRIX
1 2 3
2 4 5
3 5 6
THE GIVEN MATRIX IS SYMMETRIC.
THE SUM OF THE LEFT DIAGONAL = 11
THE SUM OF THE RIGHT DIAGONAL = 10

Example 2
INPUT:
M = 4
Enter elements of the matrix:
7 8 9 2
4 5 6 3
8 5 3 1
7 6 4 2
OUTPUT:
ORIGINAL MATRIX
7 8 9 2
4 5 6 3
8 5 3 1
7 6 4 2
THE GIVEN MATRIX IS NOT SYMMETRIC.
THE SUM OF THE LEFT DIAGONAL = 17
THE SUM OF THE RIGHT DIAGONAL = 20

Example 3
INPUT: M = 12
OUTPUT: SIZE IS OUT OF RANGE.

import java.util.Scanner;
class Symmetric{
    public static void main(String[] args){
        Scanner in = new Scanner(System.in);
        System.out.print("M = ");
        int m = Integer.parseInt(in.nextLine());
        if(m < 3 || m > 9){
            System.out.println("SIZE IS OUT OF RANGE");
            return;
        }
        int a[][] = new int[m][m];
        System.out.println("Enter elements of the matrix:");
        for(int i = 0; i < m; i++){
            for(int j = 0; j < m; j++){
                a[i][j] = Integer.parseInt(in.nextLine());
            }
        }
        int left = 0;
        int right = 0;
        boolean isSymmetric = true;
        System.out.println("ORIGINAL MATRIX");
        for(int i = 0; i < m; i++){
            for(int j = 0; j < m; j++){
                System.out.print(a[i][j] + "\t");
                if(a[i][j] != a[j][i])
                    isSymmetric = false;
                if(i == j)
                    left += a[i][j];
                if(i + j == m - 1)
                    right += a[i][j];
            }
            System.out.println();
        }
        if(isSymmetric)
            System.out.println("THE GIVEN MATRIX IS SYMMETRIC.");
        else
            System.out.println("THE GIVEN MATRIX IS NOT SYMMETRIC.");
        System.out.println("THE SUM OF THE LEFT DIAGONAL = " + left);
        System.out.println("THE SUM OF THE RIGHT DIAGONAL = " + right);
    }
