2. Implement a map, which is an abstract data structure that stores a collection of (key, value) pairs. Your implementation should at least support the following operations: + initialize the map + get the size of the map + insert a pair (key, value) into the map + get the value for a given key + remove the pair from the map with a given key Please include your test cases in the code. 2.
