Conversion to Arabic

Of course, you can use the raw Roman numbers, but whats the fun of that if you can use Arabic numerals? Unfortunately, Roman numerals isn't really standardized, so the scripts you made by hand might not work. I'm using the Roman Python library to encode and decode numerals. (If you don't have one, it will automatically install it using pip (I guess))

To convert romanF to number, take this cat program:

DCDM

First, the roman number is split into the longest valid Roman numeral:

DC D M

Then it gets converted to Arabic numeral:

600 500 1000

Examples

The HELLO program:

IIIIIIIICXIIIIIIIIILVMXCXIXILLVMXDCVMXVVVCLILIXXVMLDCVMLIIIIIIICXIXILLVMXDCVMXCLILIXXVMLDCVMLIIICXIXILLVMXDCVMX

or, in Arabic numeral:

3 3 2 113 3 3 55 1090 19 1 50 55 1010 605 1015 5 5 151 59 15 1050 605 1053 3 1 119 1 50 55 1010 605 1090 51 59 15 1050 605 1053 119 1 50 55 1010 605 1010
