In this article, we will discuss different ways to iterate over a map in reverse order. Introduction Map store the elements in sorted order of keys. For example, if you store following elements in map i.e. {“aaa”, 10}, {“ddd”, 11}, {“bbb”, 12}, {“ccc”, 13} It will internally store the elements in sorted order of keys
