The knowledge we assume is basic programming in a language and mathematical skills related to topics including matrices, set operations, and statistical concepts. The reader should have the ability to write pseudo code based on a flowchart or a specified algorithm. Writing functional code, testing, following guidelines, and building a complex project in the Go language are the prerequisites that we assume in terms of reader skills.

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Let's take a look at the len function in the next section."

A block of code is set as follows:

//main package has examples shown
// in Hands-On Data Structures and algorithms with Go book
package main

// importing fmt package
import (
  "fmt"
)
// main method
func main() {
  fmt.Println("Hello World")
}

Any command-line input or output is written as follows:

go build
./hello_world

Bold: Indicates a new term, an important word, or words that you see on screen.
