        }
        printf("%d %d %d\n", max, maxi, maxj);

}

C++ :

#include <stdio.h>
int main() {
	int i, j, max, maxi, maxj;
	int val[3][4];
	for (i = 0;i < 3;i++) {

				maxi = i;
				maxj = j;
			}
		}
	}
	printf("%d %d %d\n", max, maxi, maxj);
	return 0;
}

Pascal :

var
  i,ia,ja,j,k,max:longint;

begin
  max:=-maxlongint;
  for i:=1 to 3 do 
    for j:=1 to 4 do begin
      read(k);
      if(k>max) then begin
        max:=k;
        ia:=i;
        ja:=j;
      end;
    end;
  writeln(max,' ',ia-1,' ',ja-1);
end.

Java :

import java.util.Scanner;


public class Main {

	public static void main(String[] args) {

		int arr[][]=new int [3][4];
		Scanner cin = new Scanner(System.in);
		for( int i=0;i<3;i++ )
