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.

Variadic functions

A function in which we pass an infinite number of arguments, instead of passing them one at a time, is called a variadic function. The type of the final parameter is preceded by an ellipsis (...), while declaring a variadic function; this shows us that the function might be called with any number of arguments of this type.

Variadic functions can be invoked with a variable number of parameters. fmt.Println is a common variadic function, as follows:

//main method
func main() {
var customers []Customer
customers = GetCustomers()
fmt.Println("Before Insert",customers)
var customer Customer
customer.CustomerName = "Arnie Smith"
customer.SSN = "2386343"
customers = GetCustomers()
fmt.Println("After Insert",customers)

Run the following commands:

go run database_operations...
