How do we remove duplicates from an iterator and put it in sorted order?

Question

Sample input:

it = iter(["black", "aqua", "aqua", "black", "black", "blue", "aqua", "blue", "fuchsia", "gray", "gray", "green", "green", "aqua", "lime", "lime"])

Expected output:

it = iter(["aqua", "black", "blue", "fuchsia", "gray", "green", "lime",])

Similar questions have been asked before:

someone previously asked how to remove duplicates from an iterator about implementing the iterator protocol and their own class with __iter__ and __next__ methods defined.
someone previously asked how to remove duplicates from an iterator restricted to not using Python's built-in set class.

There are almost no restrictions on this question other than it be written in Python.

# oit ..... output iterator
# iit ..... input iterator  
oit = sorted(set(iit))

`oit` is a list, not an iterator. You'll need to wrap it in `iter` if you want an iterator i.e. `oit = iter(sorted(set(iit)))` – Nick Apr 23 '23 at 01:37
