You can use a hashmap to store indices rather than a set so you don't have to use sorted()

there's no hashmap in python, it is called dict. In this case I wanted to created clear solution (not necessarily efficient)

Yes, it is called "dictionary" but underneath it is nothing more than a hashtable, no matter what you call it. <a href="https://github.com/python/cpython/blob/master/Objects/dictobject.c">https://github.com/python/cpython/blob/master/Objects/dictobject.c</a>
