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

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>
#include<sstream>
using namespace std;

int main()
{

int A,B;
cin>>A>>B;
if(A+B > A-B && A+B>A*B)
	cout<<A+B;
else if (A-B>A+B && A-B>A*B)
	cout<<A-B;
else if(A*B>A+B && A*B>A-B)
	cout<<A*B;
