Learn Data Structures and Algorithms with Golang

By: Bhagvan Kommadi

Overview of this book

Golang is one of the fastest growing programming languages in the software industry. Its speed, simplicity, and reliability make it the perfect choice for building robust applications. This brings the need to have a solid foundation in data structures and algorithms with Go so as to build scalable applications. Complete with hands-on tutorials, this book will guide you in using the best data structures and algorithms for problem solving. The book begins with an introduction to Go data structures and algorithms. You'll learn how to store data using linked lists, arrays, stacks, and queues. Moving ahead, you'll discover how to implement sorting and searching algorithms, followed by binary search trees. This book will also help you improve the performance of your applications by stringing data types and implementing hash structures in algorithm design. Finally, you'll be able to apply traditional data structures to solve real-world problems. By the end of the book, you'll have become adept at implementing classic data structures and algorithms in Go, propelling you to become a confident Go programmer.

Maps are used to keep track of keys that are types, such as integers, strings, float, double, pointers, interfaces, structs, and arrays. The values can be of different types. In the following example, the language of the map type with a key integer and a value string is created (maps.go):

var languages = map[int]string {
3: “English”,
4: “French”,
5: “Spanish”

Maps can be created using the make method, specifying the key type and the value type. Products of a map type with a key integer and value string are shown in the following code snippet:

var products = make(map[int]string)
products[1] = “chair”
products[2] = “table”

A for loop is used for iterating through the map. The languages map is iterated as follows:

var i int
var value string
for i, value = range languages {
