C++ Data Structures and Algorithm Design Principles

By: John Carey, Anil Achary, Shreyans Doshi, Payas Rajan

Overview of this book

C++ is a mature multi-paradigm programming language that enables you to write high-level code with a high degree of control over the hardware. Today, significant parts of software infrastructure, including databases, browsers, multimedia frameworks, and GUI toolkits, are written in C++. This book starts by introducing C++ data structures and how to store data using linked lists, arrays, stacks, and queues. In later chapters, the book explains the basic algorithm design paradigms, such as the greedy approach and the divide-and-conquer approach, which are used to solve a large variety of computational problems. Finally, you will learn the advanced technique of dynamic programming to develop optimized implementations of several algorithms discussed in the book. By the end of this book, you will have learned how to implement standard data structures and algorithms in efficient and scalable C++ 14 code.

Strongly Connected Components

In the previous chapters, we discussed several classifications of graphs. Among the most common ways of describing the characteristics of a graph is stating whether it is directed or undirected. The latter defines graphs in which the edges are bidirectional by default (if node A has an edge connecting to node B, then node B has an edge connecting to node A), while the former describes graphs with edges oriented toward specific 'directions'.

Imagine you are an employee for a video hosting website and are tasked with producing statistics about commonalities between subscribers to various channels. Your company is particularly interested in discovering patterns between the individuals who subscribe to certain channels and the subscriptions of the channels' respective owners, hoping to gain greater insight into how their targeted advertising service should be directed. The service your company provides has become rather expansive recently, so you need...
