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

function Main(input){
var A = input.split(" ")[0];
var B = input.split(" ")[1];
var add = new Number(A) + new Number(B);
var dev = A - B;
var mul = A * B;
if(add >= dev && add >= mul){
  console.log(add);
}else if(dev >= add && dev >= mul){
  console.log(dev);
}else{
  console.log(mul);
}
}
  Main(require('fs').readFileSync('/dev/stdin','utf8'));
