Chapter 1: The Role of Algorithms in Computing

@fabioyamate @andrielfn @laurocaetano just finished the answers for chapter 1.

However didn't answer one of the exercises.
Oh, forgot to mention. I'm using `dvipng`. I first use plain `latex` to generate the `dvi` file and then use that command that generates PNG files, one for each page. It's really great. Not sure it comes with MacTex though.
