Problem:
Score : 200 points

Problem Statement

You are given two positive integers A and B. Compare the magnitudes of these numbers.

Constraints

1 ≤ A, B ≤ 10^{100}

Neither A nor B begins with a 0.

Input

Input is given from Standard Input in the following format:

A
B

Output

Print GREATER if A>B, LESS if A<B and EQUAL if A=B.

Sample Input 1

36
24

Sample Output 1

GREATER

Since 36>24, print GREATER.

Sample Input 2

850
3777

Sample Output 2

LESS

Sample Input 3

9720246
22516266

Sample Output 3

LESS

Sample Input 4

123456789012345678901234567890
234567890123456789012345678901

Sample Output 4

LESS

#include <iostream>

#include <vector>
#include <set>
#include <cmath>

using namespace std;

int main(void)
{
    string a, b;
    cin >> a >> b;
    if (a.length() > b.length())
        cout << "GREATER" << endl;
    else if (b.length() > a.length())
        cout << "LESS" << endl;
    else
    {
        int i = 0;
        while (i < a.length() && a[i] == b[i])
            i++;
        if (i == a.length())
            cout << "EQUAL" << endl;
        else if (a[i] > b[i])
            cout << "GREATER" << endl;
        else if (b[i] > a[i])
            cout << "LESS" << endl;
    }
