Problem:
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 (Clang 3.8.0) (judge verdict: Wrong Answer)

#include <iostream>

using namespace std;

int main()
{
int a , b;
cin>>a>>b;
int mult = a*b;
int sum = a+b;
int mod = a-b;
if(mult>sum && mult>mod) cout<<mult;
else if(sum>mult && sum>mod) cout<<sum;
else if(mod>sum && mod>mult) cout<<mod;


    return 0;
