3.6: explaining maps with data structures terminology #190
Description
This part explains dictionaries using terminology from a data structures course.
Coming from Python directly, I did not understand the parts that mentioned TreeMaps and HashMaps. A small explanation or a reference to an article explaining the difference would add to this section.

a few lines like:
HashMap does not maintain any order neither based on key nor on basis of value, If we want the keys to be maintained in a sorted order, we need to use TreeMap.
TreeMap always keeps the elements in a sorted(increasing) order, while the elements in a HashMap have no order.
Just to elaborate on the difference: give a refresher to those who know it and a simple explanation for those who don't.
