Hash Table#
This chapter is about the C++ Standard Template Library’s std::unordered_map
and how it can help your programming.
With hash-based data structures, you can store and retrieve information quickly, like a well-organized library. Hash tables allow you to efficiently manage data by inserting, locating, and removing elements, even from large datasets. C++’s std::unordered_map
makes it easy to use hash tables without manual implementation.
What this chapter covers:
Exploring std::unordered_map: Dive into the C++ Standard Template Library’s std::unordered_map container, learning how to use it effectively for mapping keys to values.
Problem-Solving with Hash Tables: Learn strategies for solving many problems using hash tables, including frequency counting, anagram detection, and more.
