Este programa consiste en que dado un numero romano (escrito todo en mayuscula, como XIV), le devuelva el valor en el sistema decimal.
El programa fue testeado con los siguientes ejemplos:
VI = 6;
XXI = 21;
LXVII = 67
IV = 4;
IX = 9;
XL = 40;
XC = 90;
CD = 400;
CM = 900
XIII = 13;
XIV = 14;
XXXIII = 33;
XXXIV = 34
XIX = 19;
LIV = 54;
CXXIX = 129
Espero les sirva, y lo compartan con sus amigos :S
