Go for Beginners — Hello World + Reading Input

Описание: In this video, we start our Go programming journey by writing the classic “Hello, World!” and then gradually move into handling *user input* — the right way.
I’ll walk you through how `fmt.Print` and `fmt.Println` actually differ, why `fmt.Scan` often behaves unexpectedly, and how to handle that using `bufio.NewReader`.

We’ll also cover how to convert user input from string to integer using `strconv.Atoi`, and properly handle errors in Go with `if err != nil`.
The goal is to make you comfortable with Go’s input/output fundamentals while building a strong foundation for writing reliable backend code.

If you’re new to Go or switching from another language like Python or JavaScript, this tutorial will help you understand the Go way of doing things — clean, simple, and
