Overview of this book

C++ is a general-purpose programming language which has evolved over the years and is used to develop software for many different sectors. This book will be your companion as it takes you through implementing classic data structures and algorithms to help you get up and running as a confident C++ programmer. We begin with an introduction to C++ data structures and algorithms while also covering essential language constructs. Next, we will see how to store data using linked lists, arrays, stacks, and queues. Then, we will learn how to implement different sorting algorithms, such as quick sort and heap sort. Along with these, we will dive into searching algorithms such as linear search, binary search and more. Our next mission will be to attain high performance by implementing algorithms to string datatypes and implementing hash structures in algorithm design. We'll also analyze Brute Force algorithms, Greedy algorithms, and more. By the end of the book, you'll know how to build components that are easy to understand, debug, and use in different applications.

Getting acquainted with hash tables


Suppose we want to store a collection of numbers, for instance, a phone number, and let's say we have approximately 1,000,000 numbers. In previous chapters, we also discussed several data structures, and here we can consider using one of them. We can use an array or a list, but we have to provide a million slots of data in the array. If we need to add some phone numbers again, we have to resize the array. Also, the operation of searching will be costly, since we have to use a linear search algorithm with time complexity O(N), where the time consumption will increase if we add data to the list. Indeed, we can use a binary search algorithm with O(log N) time complexity if we manage to sort the elements of the list containing the bunch of phone numbers; however, the insert operation will be costly, since we have to maintain the sorted list.

Another data structure we can choose is the balanced binary search tree. It can give us a moderate time complexity, since...
