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,m,n,p;
    scanf("%d%d",&A,&B);

    m=A+B;
    n=A-B;
    p=A*B;

    if(m>n && m>p)
    {
        printf("%d\n",m);
    }
    else if(n>m && n>p)
    {
        printf("%d\n",n);
    }
    else if(p>m && p>n)
    {
        printf("%d\n",p);
    }
    return 0;
}
