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: Wrong Answer)

#include<iostream>
using namespace std;

int main()
{
    int a,b,add,Min,mul;
    cin >>a>>b;

    add = a + (b);
    Min = a -(b);
    mul = a* (b);

    if(a<=100 && a>=-100 && b<=100 && b>=-100)
    {
        if(add>Min && add>mul)
    {
        cout <<add;
    }
    else if(Min>add && Min>mul)
    {
        cout <<Min;
    }
    else if(mul>add && mul>Min)
    {
        cout <<mul;
    }
  }

    return 0;
