Polyglot implementations of "safadeza" calculus.

The Problem

Sometimes, you want to know how safad(o/a) - a Brazilian Portuguese word for naughty - someone is. A very popular Brazilian musician desbribes himself as being

99%
an angelical and perfect person; but the other
1%
is naughty - as you can see in the lyrics.

A very clever professor from a state university in Brazil proposed a way o calculing how safado some is based on his/her date of birth.

The magical formula needs:

  • A

    sum
    function which takes an
    int
    a returns the sum of it with all its previous positive integers, e.g.
    sum(5) = 5 + 4 + 3 + 2 + 1
    .
  • A

    safadeza
    function which is given by:

safadeza = sum(month) + (year / 100) * (50 - day)
  • An
    angel
    function which is given by:

angel = 100 - safadeza

The last two functions MUST return a float

So this repo is for writing code that shows others how safado they are.

I look forward to seeing what you come up with c:

Motivation

Where everything started.

The programming question which quotes Wesley Safadão and turned to be a hit on the web.

It all started when a professor from the Quixadá campus of the Federal University of Ceará - Universidade Federal do Ceará (UFC) - Jefferson de Carvalho called everyone's attention by using a hit of the sertanejo and forró music to teach imperative programming logic to his students.

He was inspired by the song Aquele 1%, which is a success from the duo Marcos & Belutti featuring a very popular Brazilian musician, Wesley Safadão, to write his logical challenge.

If you'd like to find out more content about this funny story, there are lots of good resources on the web about it.

Contributing

Basic Requirements

  • You MUST be listening to the music while coding.
  • If you have to stop listening, close the editor - your time is over!
  • Please, don' use tabs. Tabs are from Satan. Use spaces. - actually, just follow the basic styleguide.

Adding a New Implementation

  1. Just think of your own interpretation of the problem.
  2. Check if anyone has suggested this before here.
  3. Fork this project!
  4. Create a new folder with the name of the language you've used in your solution, e.g.
    javascript/
    .
  5. If the language you want to implement already has an implemention, make
    version-*
    in the folder!
  6. Put the implementation and the example in separated files.
  7. Tick the language - with
    - [x]
    in GitHub Flavored Markdown - in which you've implemented here.
  8. Commit your changes:
    git commit -m 'Add JavaScript version'
    .
  9. Push to the branch:
    git push origin master
    .
  10. Submit a pull request :)

If you'd like to contribute with a language in which the algorithm has already been implemented - but you have a new/special/different/whatever way of making -, you can make it! Just create a new folder inside the folder of the language, e.g.

javascript/browser
,
javascript/node
,
javascript/react
etc.

Adding a New Language

  1. Check if anyone has suggested this before here.
  2. Fork this project!
  3. Add the language to the languages tracking file - don't forget to obey alphabetical order.
  4. Commit your changes:
    git commit -m 'Add JavaScript to listed languages'
    .
  5. Push to the branch:
    git push origin master
    .
  6. Submit a pull request :)

Status

You can check a list of languages in which the problem's been implemented - or should've been - here.

Importance

This project may seem useless, but, amazingly, it is not.

In about two days it achieved something interesting: a deterministic algorithm said to be simple which when implemented in 40+ languages, tells us a lot! E.g.

So the lesson is: that kind of initiative shows us that in modern times not only with FizzBuzz-alike implementations you can learn programming logic/languages/ paradigms.
