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 Rust (1.42.0) (judge verdict: Accepted)

use proconio::input;

fn main(){
    input!{
        mut A: String,
        mut B: String
    }
    if A.len()>B.len() {
        print!("GREATER");
    }else if A.len()<B.len(){
        print!("LESS")
    }else{
        if A==B {
            print!("EQUAL");
        }else{
            while A.len()>=0{
                let top_of_A = A.remove(0);
                let top_of_B = B.remove(0);
                if top_of_A>top_of_B{
                    print!("GREATER");
                    break
                }else if top_of_A<top_of_B{
                    print!("LESS");
                    break
                }
            }
        }
