I was confused as to what some lines in binary_search_itr(xs, y) were doing. I don't think they're necessary. If I'm correct, this code should be easier to understand.
Thanks! I've added +1 extra credit in sakai. This isn't your first pr, and normally I'd only offer a smaller ec for subsequent prs, but the contribution is substantial so I'm awarding more extra credit :)
