Describe your change:

• Add an algorithm?
• Fix a bug or typo in an existing algorithm?
• Documentation change?

I made the following changes:

• Commit 1:
  Add a extra blank line to end of readme.md file to follow convention

• Commit 2:
  Most of the tests on this repo are in a /test folder inside their respective folder. Even folders with only one algorithm and one test. Thus I put all the other tests not following this convention to follow them.

Altough one of the rules is to change only one algorithm file per PR, there was no change to the actual algorithm, and it's more of a structural change. Thus I feel like the commit should be judged as a whole instead of separate commits/PR.
