The third method forces the compiler to convert n
to string.
Concatenating (adding strings together by using the + operator) even an empty
string in this case with anything else will always result in a string. So the
number has to be converted to make the resulting string. Anyway, this is a weird
method to do such thing and can be misunderstood, use the 2 above.
