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

import scala.util.control.Breaks

object Main extends App {
  val b = new Breaks
  var flag = false
  val str1 = readLine
  val str2 = readLine
  if (str1.length > str2.length) {
    println("GREATER")
    flag = true
  }
  if (str1.length < str2.length) {
    println("LESS")
    flag = true
  }
  if (!flag) {
    b.breakable {
      for (i <- 0 to str1.length - 1) {
        if (str1(i) > str2(i)) {
          println("GREATER")
          b.break
        }
        else if (str1(i) < str2(i)) {
          println("LESS")
          b.break
        }
        if (str1(i) == str2(i) && i == str1.length - 1) {
          println("EQUAL")
        }
      }
    }
  }
