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 5.4.1) (judge verdict: Wrong Answer)

#include<stdio.h>
int main()
{
    int A,B,a,b,c;
    scanf("%d%d",&A,&B);
    a=A+B;
    b=A-B;
    c=A*B;
    if(A && B <=0)
    {
        printf("%d\n\n",c);
        printf("The largest number among A+B=%d,A-B=%d,and A*B=%d is %d",a,b,c,c);
    }
    else if(a >= c && b)
    {
        printf("%d\n\n",a);
        printf("The largest number among A+B=%d,A-B=%d,and A*B=%d is %d",a,b,c,a);
    }
      else if(b >= a && c)
    {
        printf("%d\n\n",b);
        printf("The largest number among A+B=%d,A-B=%d,and A*B=%d is %d",a,b,c,b);
    }
    else if(c >= a && b)
    {

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

        printf("The largest number among A+B=%d,A-B=%d,and A*B=%d is %d",a,b,c,c);
    }
      else
    {
          printf("%d\n\n",c);

        printf("The largest number among A+B=%d,A-B=%d,and A*B=%d is %d",a,b,c,c);

    }
