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)

"use strict";

const input = require("fs").readFileSync("/dev/stdin", "utf8");

const inputs = input.split(" ");
const A = Number(inputs[0]);
const B = Number(inputs[1]);

const main = (A, B) => {
    let add, sub, multi = 0;
    add = A + B;
    sub = A - B;
    multi = A * B;

    return  Math.max(add, sub, multi);
};

console.log(main(A, B));
