Problem:
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: Runtime Error)

import  scala.io.StdIn
object Main extends App {
  var a = StdIn.readLine()
  var b = StdIn.readLine()
  
  (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{
        for(i <- 0 to a.length){
          if(a(i) > b(i)) println("GREATER")
          else if(a(i) < b(i)) println("LESS")
        }
      }
    }
    case _ => println("")
  }
