Input Samples	Output Samples
5 6 7 8	DIFERENCA = -26

0 0 7 8

DIFERENCA = -56

5 6 -7 8

DIFERENCA = 86

Solution in C language :

#include<stdio.h>
int main()
{
 int a, b, c, d;
 scanf("%d%d%d%d", &a, &b, &c, &d);
 printf("DIFERENCA = %d\n", a * b - c * d);


 return 0;
}









Solution in C++ language :






#include<iostream>

using namespace std;



int main()

{

 int a, b, c, d;

 cin >> a >> b >> c >> d;

 cout << "DIFERENCA = " <<a * b - c * d << endl;



 return 0;

}

Solution in Java language : 

import java.util.Scanner;


public class URI_1007 {


 public static void main(String[] args) {
         Scanner input =new Scanner(System.in);
                int a, b, c, d, difference;
         a = input.nextInt();
         b = input.nextInt();
         c = input.nextInt();
         d = input.nextInt();
         difference = a * b - c * d;
  System.out.print("DIFERENCA = "+ difference +"\n");
 }
}
