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 (Clang 3.8.0) (judge verdict: Accepted)

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