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 OCaml (4.02.3) (judge verdict: Accepted)

let () = Scanf.scanf "%s\n%s" @@ fun a b ->
  if String.length a < String.length b then print_endline "LESS"
  else if String.length a > String.length b then print_endline "GREATER"
  else
    try
      Array.init (String.length a) (fun i -> Char.code b.[i] - Char.code a.[i])
      |> Array.to_list
      |> List.find (( <> ) 0)
      |> (fun d -> if 0 < d then "LESS" else "GREATER")
      |> print_endline
    with Not_found -> print_endline "EQUAL"
