Maps are guaranteed to be efficient. In general, inserting a new item into a map is supposed to take O(lg(n)) time, where n is the number of items in the map. However, if you want to insert at a specific location (specified by an iterator), it takes on average O(n) time. You...

In C++ nowadays, there are at least 2 implementations of some of these. See the ATL(ActiveX Template Library) containers, like CRBMap, CRBTree, CSimpleArray, CAtlArray, and the STL (Standard Template Library) implementations, like Hash_Set, Map, MultiMap, vector, in MSDN....

CSCI-1200 Data Structures — Fall 2018Homework 8 — Bidirectional MapsIn this assignment you will build a custom data structure named bidirectional_map. A bidirectional_mapis similar to an STL map, in that it stores the association between key and value data. Like a map, insertingand erasing ...
Thewrdcountdemo can be built for 16-bits using VC++ 1.52c, or 32-bits using VC++ 4.2 or higher. The 16-bit version does not handle the STL maps since they are unavailable in that environment, and displays data for only theFastMaps!and MFC classes. ...
