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

Solution in Rust (1.42.0) (judge verdict: Accepted)

use proconio::{fastout, input};

#[fastout]
fn main() {
    let a: String;
    let b: String;
    input! {a: String, b: String};

    if a.len() > b.len() {
        println!("GREATER")
    } else if a.len() < b.len() {
        println!("LESS")
    } else {
        let mut t = 'e';

        for i in 0..a.len() {
            if &a[i..i + 1] > &b[i..i + 1] {
                println!("GREATER");
                t = 'a';
                break;
            } else if &a[i..i + 1] < &b[i..i + 1] {
                println!("LESS");
                t = 'a';
                break;
            }
        }

        if t == 'e' {
            println!("EQUAL");
        }
    }
}
