get(k): Returns the value v associated with key k, if such an entry exists; otherwise returns null.
put(k, v): Associates value v with key k, replacing and returning any existing value if the map already contains an entry with key equal to k.
remove(k): Removes the entry with key equal to k, if one exists, ...
