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.

using System;
namespace AT
{
  class A
  {
    static void Main()
    {
      var read = Console.ReadLine();
      string[] readline = read.Split(' ');
      int a=int.Parse(readline[0]);
      int b=int.Parse(readline[1]);
      int ans=MAX(a,b);
      Console.WriteLine(ans);
    }
    static int MAX(int a,int b)
    {
      int p=a+b;
      int x =a*b;
      int m = a-b;
      if(p>=x && p>=m)
      {
        return p;
      }
      else if(x>=p && x>=m)
      {
        return x;
      } 
      else
      {
        return m;
      }
    }
  }
