Module Overview
Ruby is a smart, functional, and object-oriented programming language that blends the best features of scripting power with user-friendly syntax. In this module, we’ll dive into OOP in Ruby with hands-on practice using interactive exercises and illustrations. We'll start by creating and managing Ruby objects. Next, we’ll explore Ruby methods and blocks, essential tools in Ruby programming. Finally, we'll delve into Ruby classes and how they are used to implement OOP principles.

Ruby OOP (Object-Oriented Programming)

## Problem statement

Given a `month` containing a number from one to 12 and a `leap_year` variable set to `true` or `false`, return the number of days in that month.

### Examples

```ruby
Input:
month = 3
leap_year = true

Output:
result = 31
```
```ruby
Input:
month = 2
leap_year = true

Output:
result = 29
