Exercise: Messages list service

This exercise consists on creating a REST service that allows external applications to create and manage message lists, basically there are two contexts:

• User management: Services that allow the register, update or removal of users
• Messages management: Services that allow message exchange between registered users

So the service will allow users to be registered, send messages between them and retrieve all the messages directed to a specific user.

Word count

TLDR: The program to write must calculate words frequency from a given file.

We will provide you a file with some text on it, and you have to open it and find the frequencies of all words in it having the following requirements:

• Assume a valid UTF-8 input file
• All words must be processed in lower case (ignore case) Output must be sorted by word alphabetically
• Output must have one entry per word, having its frequency next to it
