        length = len(x_num)
        for i in range(length):
            if x_num[i] == 'A':
                d_num += 10 * 16 ** (length - 1 - i)
            elif x_num[i] == 'B':
                d_num += 11 * 16 ** (length - 1 - i)
            elif x_num[i] == 'C':
                d_num += 12 * 16 ** (length - 1 - i)
            elif x_num[i] == 'D':
                d_num += 13 * 16 ** (length - 1 - i)
            elif x_num[i] == 'E':
                d_num += 14 * 16 ** (length - 1 - i)
            elif x_num[i] == 'F':
                d_num += 15 * 16 ** (length - 1 - i)
            else:
                d_num += int(x_num[i]) * 16 ** (length - 1 - i)
        print(d_num)
    except:
        break
