**Hexadecimal** is a base 16 counting system that goes from `0` to `f`. Your job is to make a counter that will display these numbers.
**Example:**
$ python counter.py
1 2 3 4 5 6 7 8 9 a b c d e f 10 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f 20 21 22 23 24 25 26 27 28 29 2a 2b 2c 2d 2e 2f 30
**Rules:**
* The numbers may be separated by spaces, tabs, or new lines.
* The minimum number you must go to is `30` (48 in decimal).
* You may also make the program print numbers forever until it is stopped.
* Letters may be in uppercase or lowercase (`A` or `a`).
* No built in functions allowed (that directly affect hexadecimal conversions/counting).
* Leading zeros are allowed
* It may start from `1` or `0`
* Shortest code wins!
