Functional programming is a paradigm that emphasizes expressing program logic as compositions of pure functions. PHP is a good fit for functional programming as functions are first-class citizens in its userland.
 
This course introduces you to the core concepts of functional programming, like pure functions, immutable data structures, and referential transparency. From there, you'll explore ways to handle errors with default values and callbacks while also exploring sum types such as Either or Maybe. Next, you'll look at functors before diving deep into monads, including IO, State, Reader, and List.
 
By the end of this course, you'll have a keen understanding of how to apply these principles in practice through a worked-out project. Not only will you know another way to program, but you’ll also feel confident enough to apply these ideas to your projects in PHP.

## Problem statement

Write a program similar to the previous challenge that performs the same formatting on sentences, but this time facilitated by `RabbitMQ` message brokerage.


### Formatting rules

- Remove any dots or underscores from the start.
- Append a period at the end.
- Convert any starting lowercase character to its uppercase version.


### Example sentences

Consider the list of sentences below to apply the encoding and the formatting:
