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 C++14 (GCC 5.4.1) (judge verdict: Wrong Answer)

#include <iostream>
#include <string>
using namespace std;
int main(void){
    // Here your code !
    //GREATER、A<B のときLESS、A=B のときEQUAL

    std::string str1,str2;
    cin >> str1 >> str2;
    
    
    
    if(str1.size() > str2.size()){
        cout << "GREATER" << endl;
    }else if(str1.size() < str2.size()){
        cout << "LESS" << endl;
    }else{
        if(str1 == str2){
            cout << "EQUAL" << endl;
        }else{
            for(int i = str1.size()-1; i >= 0; i-- ){
                if(str1[i] > str2[i]){
                    cout << "GREATER" << endl;
                    return 0;
                }else if(str1[i] < str2[i]){
                    cout << "LESS" << endl;
                    return 0;
                }
            }
        }
    }
