  }

  public static long convertOctalToBinary(int octalNumber) {
    int decimalNumber = 0, i = 0;
    long binaryNumber = 0;

    while (octalNumber != 0) {
      decimalNumber += (octalNumber % 10) * Math.pow(8, i);
      ++i;
      octalNumber /= 10;
    }

    i = 1;

    while (decimalNumber != 0) {
      binaryNumber += (decimalNumber % 2) * i;
      decimalNumber /= 2;
      i *= 10;
