Roman Numbers (1 to 3999)

To interpret  Roman numbers we have first to find where are the double characters which represents numbers 900, 400, 90, 40, 9 and 4.
If we found one then we have to check from an exclude list if in the right side there are one or more, and if we found one then this is an invalid input.
Also when we found one we can replace it with an internal code.



This is the output of this program:
MMMCMXCIX=3999
LXXIIX=invalid
MMXVII=2017
LXXIX=79
CXCIX=199
MCMXCIX=1999
MMMDCCCLXXXVIII=3888
CMXI=911
M=1000
MCDXLIV=1444
CCCC=invalid
IXV=invalid
XLIXL=invalid
LXXIIX=invalid
IVM=invalid
XXXIX=39
XXXX=invalid
XIXX=invalid
IVI=invalid
XLIX=49
XCIX=99
XCIV=94
XLVIII=48
XLCD=invalid
