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 C++14 (GCC 5.4.1) (judge verdict: Accepted)

#include <iostream>
#include <string>
using namespace std;

int main() {
	int A;
	cin >> A ;
	int B;
	cin >> B;
	
	if ( A+B >= A-B && A+B >= A*B){
		cout << A+B << endl;
	} else if (A-B >= A+B && A-B >= A*B){
		cout << A-B << endl;
	} else if (A*B >= A+B && A*B >= A-B){
		cout << A*B << endl;
	}
	
	// your code goes here
	return 0;
