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 Go (1.6) (judge verdict: Wrong Answer)

package main

import (
	"fmt"
)

func main() {
	var a, b int
	
	fmt.Scanf("%d", &a)
	fmt.Scanf("%d", &b)
	
	calc := [3]int{a+b,a-b,a*b}

	fmt.Printf("%d\n", calc[2])

	result := calc[0]
	for i := 0; i < len(calc); i++ {
		if calc[i] > result {
			result = calc[i]
		}
	}
	fmt.Printf("%d", result)
	
}
