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!
