importjava.util.*;
class Q4
{
    public void main()
    {
       int RC[][] = new int [4][4];
       int r = 0, c = 0, max = 0;
       Scanner sc = new Scanner(System.in);
       for(r = 0; r<4; r++)
       {
            for(c = 0; c<4; c++)
           {
                 System.out.print(" Enter value for cell number "+r+""+c+":: ");
                 RC[r][c] = sc.nextInt();
           }
       }
       max = RC[0][0];
       for(r = 0; r <4; r++)
       {
           if(RC[r][r]> max)
           {
               max = RC[r][r];
           }
       }
       System.out.print(" Largest element = "+ max);
    }
