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 (2.13.1) (judge verdict: Accepted)


object Main extends App {
  
  val sc = new java.util.Scanner(System.in)
  val a = sc.next()
  val b = sc.next()
  
  if (a.length > b.length) {
    println("GREATER")
  } else if (a.length < b.length) {
    println("LESS")
  } else {
    a.zip(b).find{case (x, y) => x != y} match {
      case Some((x, y)) if x > y => println("GREATER")
      case Some((x, y)) if x < y => println("LESS")
      case None => println("EQUAL")
    }
  }  
}
