DWITE Online Computer Programming Contest, October 2008, Problem 4
Although today's use of roman numerals is typically limited to movie titles or pages preceding the main part of a book (and thus are typically small), lets build a Roman-to-Decimal converter anyway. Just for the LOLs.
The input will contain 5 lines, Roman Numerals with values
The output will contain 5 lines, decimal values of the input numbers.
For your reference, symbols are as follows:
I 1 V 5 X 10 L 50 C 100 D 500 M 1000
Numbers in between the symbols are constructed by adding the symbols together (
II for 2); or subtracting, by placing a smaller symbols, in front of a larger one (
IV for 4).
Note: be cautious that the numbers are slightly more complicated than simply adding the values of symbols in order. While
XIII (11, 12, 13) are simple enough,
XIV (14) breaks the patterns (that is, it is not , but )
