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

import java.util.*;

public class Main {
    public static void main(final String[] args) {
        Scanner sc = new Scanner(System.in);
        String a = sc.next();
        String b = sc.next();
        if (a.length() > b.length()) {
            System.out.println("GREATER");
            return;
        } else if (a.length() < b.length()) {
            System.out.println("LESS");
            return;
        }

        int p = 0;
        while (p < a.length()) {
            if (a.charAt(p) > b.charAt(p)) {
                System.out.println("GREATER");
                return;
            } else if (a.charAt(p) < b.charAt(p)) {
                System.out.println("LESS");
                return;
            }
            p++;
        }
        System.out.println("EQUAL");
    }
