This one was relatively easy. Just copied the base code from the IsIsogram(). Got it right first try too. This is exciting.
bool FBullCowGame::IsLowercase(FString Word) const
{
// treat 0 and 1 letter words as lowercase
if (Word.length() <= 1) { return true; }
TMap<char, bool> LetterSeen; // setup our map
for (auto Letter : Word) // for all letters of the word
{
if ( !islower( Letter ) ) {
return false;
}
}
return true; // for example: in cases where /0 is entered}
