Make a simple program that reads four variables named A, B, C and D. Calculate and print the difference of the product of A and B with the product of C and D (A * B - C * D).

Input

The input file contains 4 integer numbers.

Output

Print DIFERENCA (DIFFERENCE in portuguese) according to the following example, with a blank space before and after the equal signal.

Sample Inputs	Sample Outputs
5 6 7 8	DIFERENCA = -26

0 0 7 8

DIFERENCA = -56

5 6 -7 8

DIFERENCA = 86

Solution:

#include <stdio.h>

  

int main() {

  

int A , B , C , D , DIFERENCA ;

    scanf("%d %d %d %d",&A,&B,&C,&D);

    DIFERENCA =((A*B)-(C*D));

    printf("DIFERENCA = %d\n",DIFERENCA);

     

    return 0;
