Documentation-Driven Development

The philosophy behind Documentation-Driven Development is a simple: from the perspective of a user, if a feature is not documented, then it doesn't exist, and if a feature is documented incorrectly, then it's broken.

Document the feature first. Figure out how you're going to describe the feature to users; if it's not documented, it doesn't exist. Documentation is the best way to define a feature in a user's eyes.
Whenever possible, documentation should be reviewed by users (community or Spark Elite) before any development begins.
Once documentation has been written, development should commence, and test-driven development is preferred.
Unit tests should be written that test the features as described by the documentation. If the functionality ever comes out of alignment with the documentation, tests should fail.
When a feature is being modified, it should be modified documentation-first.
When documentation is modified, so should be the tests.

Braking

Standard Braking Distance (Geschwindigkeit / 10) * (Geschwindigkeit / 10)

(Speed / 10) * (Speed / 10)

Evasive (Emergency) Braking Distance ((Geschwindigkeit / 10) * (Geschwindigkeit / 10)) / 2

((Speed / 10) * (Speed / 10)) / 2

This list is meant to be a both a quick guide and reference for further research into these topics. It's basically a summary of that comp sci course you never took or forgot about, so there's no way it can cover everything in depth. It also will be available as a gist on Github for everyone to edit and add to.

Data Structure Basics

###Array ####Definition:

Stores data elements based on an sequential, most commonly 0 based, index.
Based on tuples from set theory.

	Suppose a row of parking lot with n spots, one of them is empty and n-1 spots are occupied with cars.
	Only one operation is allowed: move one car from its position to the empty spot.
	Given a initial order of cars and a final order, output steps needed to convert initial order to final oder with that operation.
