It's got some code duplication. Who can code ~~gulf~~ golf this?

[-] TheLazyNerd@europe.pub 1 points 8 hours ago* (last edited 8 hours ago)

I'm not too good with java, but it should be something like this:

public static int convertRomanNumeral(string n){Map.of("M","DD","CD","CCCC","D","CCCCC","C","LL","XL","XXXX","L","XXXXX","X","VV","IV","IIII","V","IIIII");.forEach((k,v)->{n=n.replace(k,v);});return n.length();}

Code gulf, you say?

public static String
convertRomanNumeral(String numeral) {
    numeral = numeral.replace("America", "Mexico");
    return numeral;
}
