From problem statement: "If the number of distinct characters in one's user name is odd, then he is a male, otherwise she is a female." You're counting the number of characters, not distinct characters.
How to count them.
That's the point of the problem. You'll need to figure it out. (Hint: Google. This is very standard and you will find answers easily.)
