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

Sample Output 3

39

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

Solution in JavaScript (node.js v5.12) (judge verdict: Runtime Error)

function main(input) {
    const H = input.split(' ');
    const A = parseInt(H[0],10);
    const B = parseInt(H[1],10);

    const pls = A + B;
    const min = A - B;
    const kake = A * B;

    if(pls >= min && pls >= kake) {
      console.log(pls);
      break;
    }else if (min >= pls && min >= kake) {
      console.log(min);
　break;
    } else {
      console.log(kake);
     break;
    }

}

main(require('fs').readFileSync('/dev/stdin', 'utf8'));
