Problem Statement

You are given two integers A and B.
Find the largest value among A+B, A-B and A \times B.

Constraints

-1000 \leq A,B \leq 1000

All values in input are integers.

Input

Input is given from Standard Input in the following format:

A B

Output

Solution in C (GCC 5.4.1) (judge verdict: Wrong Answer)

#include<stdio.h>
int main()
{
      int A,B,x,y,z;

      scanf("%d %d",&A,&B);

       x = A + B;

       y = A - B;

       z = A * B;

       if(x > y && x > z){

              printf("%d\n",x);

              printf("%d+%d=%d, %d-%d=%d and %d×%d=%d. The largest among them is %d.\n",A,B,x,A,B,y,A,B,z,x);


       }


       else if(y>x && y>z){

             printf("%d\n",y);

            printf("The largest is %d-(%d)=%d.\n",A,B,y);

       }


       else

            printf("%d\n",z);

       return 0;
