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: Accepted)

#include<stdio.h>

int main(void){
int A;
int B;
scanf("%d %d",&A,&B);
if((A+B)<=(A-B) && (A*B)<=(A-B)) {
    printf("%d\n",A-B);
}else if((A-B)<=(A+B) && (A*B)<= (A+B)){
    printf("%d\n",A+B);
}else if((A-B)<=(A*B) && (A+B)<=(A*B)){
    printf("%d\n",A*B);

} else{
    printf("\n");
}
return 0;
}
