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 Scala (2.11.7) (judge verdict: Accepted)

import  scala.io.StdIn
object Main extends App {
  val a = StdIn.readLine()
  val b = StdIn.readLine()
  if(b.charAt(0).toString == "-")println("GREATER")
  else {
    (a, b) match {
      case (a, b) if (a.length > b.length) => println("GREATER")
      case (a, b) if (a.length < b.length) => println("LESS")
      case (a, b) if (a.length == b.length) => {
        if (a == b) println("EQUAL")
        else {
          var i = 0
          while (i < a.length) {
            if (a(i) > b(i)){
              println("GREATER")
              i = a.length
            }
            else if (a(i) < b(i)) {
              println("LESS")
              i = a.length
            }
            i = i+1
          }
        }
      }
      case _ => println("")
    }
