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

import java.util.*;

public class Main{
  public static void main(String[] args){
    Scanner sc = new Scanner(System.in);
    String a = sc.nextLine();
    String b = sc.nextLine();
    int idx = 0;

    if(a.length() > b.length()){
      System.out.println("GREATER");
      System.exit(0);
    }else if(a.length() < b.length()){
      System.out.println("LESS");
      System.exit(0);
    }

//charAt(-1)はout of boundsになるのでifで防ぐ
    while(a.charAt(idx) == b.charAt(idx) && idx < a.length()){
      idx++;
      if(idx == a.length()-1) break;
    }

    if(idx == a.length()-1){
      System.out.println("EQUAL");
      System.exit(0);
    }

    if(a.charAt(idx) > b.charAt(idx)){
      System.out.println("GREATER");
    }else{
      System.out.println("LESS");
    }
