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.

Arrays are the most famous data structures in different programming languages. Different data types can be handled as elements in arrays such as int, float32, double, and others. The following code snippet shows the initialization of an array (arrays.go):

var arr = [5]int {1,2,4,5,6}

An array's size can be found with the len() function. A for loop is used for accessing all the elements in an array, as follows:

var i int
for i=0; i< len(arr); i++ {
fmt.Println("printing elements ",arr[i]

In the following code snippet, the range keyword is explained in detail. The range keyword can be used to access the index and value for each element:

var value int
for i, value = range arr{
fmt.Println(" range ",value)

The _ blank identifier is used if the index is ignored. The following code shows how a _ blank identifier can be used:

for _, value = range...
