Thank you for the input, however, I am still unsure as to what the actual code for this would look like. Can anyone provide some code for me?

How can I create a method that uses a HashSet and will return the unique characters in a string?
for example
unique("racecar") ----> "e"
unique("confuse") ----> "confuse"


Thank you.
