X1348: Unique?
Write a method unique that returns true if the parameter
lookFor appears only one time (i.e., it is unique) in the array elements.
It should return false if lookFor appears 0 or more than 1 time. Note
that you don't know the type of data you are processing, so
you have to use equals() to compare objects.
