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

Solution in Java8 (OpenJDK 1.8.0) (judge verdict: Accepted)

import java.math.BigInteger;
import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		String A = sc.nextLine();
		String B = sc.nextLine();
		sc.close();
		if(A.length() > B.length()){
			System.out.println("GREATER");
		}
		else if(A.length() < B.length()){
			System.out.println("LESS");
		}
		else if(A.equalsIgnoreCase(B)){
			System.out.println("EQUAL");
		}
		else{
			BigInteger BgA = new BigInteger(A);
			BigInteger BgB = new BigInteger(B);
			int cmp = BgA.compareTo(BgB);
			if(cmp > 0){
				System.out.println("GREATER");
			}
			else{
				System.out.println("LESS");
			}
		}
	}
