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

234567890123456789012345678901

Sample Output 4

LESS

Solution in OCaml (4.02.3) (judge verdict: Time Limit Exceeded)

let e = "EQUAL" and g = "GREATER" and l = "LESS"

let f s1 s2 =
  let rec aux i =
    if i = String.length s1 then e
    else if s1.[i] > s2.[i] then g
    else if s1.[i] < s2.[i] then l
    else aux (i + i)
  in
  aux 0

let () =
  let a = read_line () and b = read_line () in
  ( if String.length a > String.length b then g
  else if String.length a < String.length b then l
  else f a b )
