Alex -- just saying return without a value in a function with a return type
is illegal -- in the case of your loops not returning within the if
statement, you need to decide what your function should return in that case
and insert that value in the return statement.

I tried that and instead of saying "missing return statement" it
said "missing return value". I just put "return;" just before
the final right-brace of the method.
Have a great day,
