I need to write a program to verify if a given roman numeral is valid

[legoses]

I don't know why, but I'm having a tough time thinking of the best way to do this. I need to parse a string of input roman numerals and output if it is a valid roman numeral or not. Any ideas!! Needs to use strings.

Thanks in advance.

Well, first you should think of all the rules that define what a Roman Numeral is. For instance, it can only contain the letters I, V, X, C, M, L...and maybe a few others I can't think of. Also, what order do these letters have to be in? Once you come up with a good list of rules a roman number has to follow, only then should you think about writing a function to implement these rules.

you should ask grigoletti, he's real good at this.
