Score : 100 points

Problem Statement

We have two integers: A and B.

Print the largest number among A + B, A - B, and A \times B.

Constraints

All values in input are integers.

-100 \leq A,\ B \leq 100

Input

Input is given from Standard Input in the following format:

A B

Output

Print the largest number among A + B, A - B, and A \times B.

Sample Input 1

-13 3

Sample Output 1

-10

The largest number among A + B = -10, A - B = -16, and A \times B = -39 is -10.

Sample Input 2

1 -33

Sample Output 2

34

The largest number among A + B = -32, A - B = 34, and A \times B = -33 is 34.

Sample Input 3

13 3

Sample Output 3

39

The largest number among A + B = 16, A - B = 10, and A \times B = 39 is 39.

Solution in C (GCC 9.2.1) (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("The largest number among A+B = %d,A-B = %d,and A×B = %dis%d\n",x,y,z,x);
       }
    else if(y>x&&y>z)
       {
           printf("%d\n",y);
         printf("The largest number among A+B = %d,A-B = %d,and A×B = %dis%d\n",x,y,z,y);
       }
    else
       {
           printf("%d\n",z);
           printf("The largest number among A+B = %d,A-B = %d,and A×B = %dis%d\n",x,y,z,z);
       }
       return 0;
