			int len = s.length();

				return pig(s.substring(0, len - 1)) + last;
			if(".,-:;'!?/<>[]{}\\\"".indexOf(first) != -1)
				return first + pig(s.substring(1));
			if("aeiouAEIOU".indexOf(first) != -1)
				return s + "way";
			int k = 1;
			boolean cap = (int)first >= 65 && (int)first <= 90;
			while(k < s.length() && "aeiouyAEIOUY".indexOf(s.charAt(k)) == -1)
