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

		int b_length = num_b.length();
		String message = "";
		if(a_length > b_length) {
			message = "GREATER";
		} else if(a_length < b_length) {
			message = "LESS";
		} else {
			int i = 0;
			for(i = 0; i < a_length; i++) {
				int a = Integer.parseInt(num_a.charAt(i) + "");
				int b = Integer.parseInt(num_b.charAt(i) + "");
