Different lessons with the following titles.

---

Implementation of 2D and 3D arrays with a contiguous block of memory. The same code tests this contiguous aspect. To run:

---

TODO:

usefulness of static/const variables and functions!

Quote:

A general rule of thumb is that your program spends 80% of its time running 20% of the code. Thus a good strategy for efficient coding is to write everything, profile your code, and optimize the parts that need it. Python’s profilers are great, and Cython allows you to do the latter step with minimal effort. - Hoyt Koepke
