Height of Rationals

Consider a fraction $b a$ . Its Height is defined as the maximum of its numerator and denominator. So, for example, the Height of would be , and the Height of would be .

Given $a$ and $b$ , find the Height of $b a$ .

Input Format

The only line of input contains two integers, $a$ and $b$ .

Output Format

Output a single integer, which is the Height of $b a$ .

Constraints

and $b$ do not have any common factors.

Sample 1:

Input

3 19

Output

Explanation:

The maximum of ${3, 19}$ is $19$ . Hence the Height of $193$ is $19$ .

Sample 2:

Input

27 4

Output

27

Solution

#include <iostream>
using namespace std;

int main()
{
int a, b;
cin >> a >> b;

if (a > b)
{
cout << a << endl;
}
else if (a == b)
{

cout << (double)a / b << endl;
}
else
{
cout << b << endl;
}
