Identifying Map Tiles Solution:

public class Kattis {
  public static void main(String[] args) {
    Scanner sc = new Scanner(System.in);
    String input = sc.nextLine();
    int level = input.length();
    int x = 0, y = 0;
    for (int i = input.length()-1; i >= 0; i--) {
      switch (input.charAt(i)) {
        case '1':
          x += Math.pow(2, level-i-1);//level - (i + 1)) * 2 == 0? 1 : (level - (i + 1)) * 2 ;
