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'
function Main(input) {
  const inputArray = input.split(' ').map(n => Number(n));
  const a = inputArray[0];
  const b = inputArray[1];
  const plus = a + b;
  const minus = a - b;
  const times = a * b;
  
  console.log(Math.max(plus, minus, times));
}

Main(require("fs").readFileSync("/dev/stdin", "utf8"));
