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.

Jump search


Jump search is a searching algorithm to find the position of a searched value in a sorted list by dividing the array into several fixed-size blocks, jumping to the first index of the block, then comparing the value of the block's first index with the searched value. If the value of the block's first index is greater than the searched value, it jumps backward to the previous block, then starts a linear search of the block.

Developing jump search algorithm

Suppose we have an array containing {8, 15, 23, 28, 32, 39, 42, 44, 47, 48} elements, and we want to find the position of value 39. We will set the jump step by the square root elements number. Since the element number of the array is 10, the step will be √10 = 3. We will now compare the value of index 0, 3, 6, and 9. When the algorithm compares array[0] with 39, the value of array[0] is lower than the searched value. It then jumps to array[3] and compares its value with 39. Since the value is lower than the searched value, it...
