This is what I came up with:

import java.io.; import java.math.; import java.security.; import java.text.; import java.util.; import java.util.concurrent.; import java.util.regex.*;

public class Solution {

private static final Scanner scanner = new Scanner(System.in);

public static void main(String[] args) {
    int n = scanner.nextInt();
    scanner.skip("(\r\n|[\n\r\u2028\u2029\u0085])?");
    if (n%2 != 0 && n>0 && n<101) {
        System.out.println("Weird");
    } else if (n%2 == 0 && n>0 && n<101) {
        if (n<6 && n>1) {
            System.out.println("Not Weird");
        } else if (n>5 && n<21){
            System.out.println("Weird");
        } else {
            System.out.println("Not Weird");
        }
    }
    scanner.close();
}

}
