-[[./Notes.org]] contains notes and solutions to exercises, as well as
-implementations of [[https://www.algorist.com/][The Algorithm Design Manual]]. All notes and source code can be
-found in this single file and the reason for that is that it uses a style of
-programming known as [[https://en.wikipedia.org/wiki/Literate_programming][Literate Programming]] with the help of Emacs, org-mode, and
-[[https://orgmode.org/worg/org-contrib/babel/intro.html][org-babel]]. Most code implementations are done in C, however, some have been also
-implemented in Python or OCaml in order to compare and contrast styles. All code
-is executable from within Emacs by just running ~C-c C-c~ while the cursor is in
-the source code block.
