I was being pretty sloppy with the code (should've posted pseudocode to
begin with, my bad) but the general logic is: cycle through each element
of the input array. If the value has not been encountered before, store
the value and key in a secondary array. If the value has been encountered
before (it's present in the secondary array), remove it from the input
array, and use the the stored key/value in the secondary array to unset
its first instance in the input array, too.
