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.

#include <bits/stdc++.h>

using namespace std;
 
 
int main() {
 
	map<string,int> mp;
	string s ;

	cin >> n;
	
	for(i=0;i<n;i++)
	{
		cin >> s;
		sort(s.rbegin(), s.rend(), greater<char>());
		count += mp[s]++;
	
	}
	
	cout << count;
