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.

The hash functions

Hash functions are used in cryptography and other areas. These data structures are presented with code examples related to cryptography. There are two ways to implement a hash function in Go: with crc32 or sha256. Marshaling (changing the string to an encoded form) saves the internal state, which is used for other purposes later. A BinaryMarshaler (converting the string into binary form) example is explained in this section:

//main package has examples shown
// in Hands-On Data Structures and algorithms with Go book
package main
// importing bytes, crpto/sha256, encoding, fmt and log package
import (
"bytes"
"crypto/sha256"
"encoding"
"fmt"
"log"
"hash"
)

The main method creates a binary marshaled hash of two example strings. The hashes of the two strings are printed. The sum of the first hash is compared...
