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 JavaScript (node.js v5.12) (judge verdict: Accepted)

function main(A,B){
  var result = [];
  Array.prototype.push.call(result,A + B,A - B, A * B);
  console.log(Math.max.call({},...result));  
}

const input = require('fs').readFileSync('/dev/stdin','utf8').split(' ');
const A = Number(input[0]);
const B = Number(input[1]);

main(A,B);
