Notes

Question 1

This is a packing problem, as described on Wikipedia. Since this is NP-hard, we know the "exact" solution might be unreachable but we could find a solution that is good enough for our needs.

Question 2

Question 3

PNG support

I chose to support PNG files through the stb files: github.com/nothings/stb. I could have implemented basic image support with the PNM format but I think it is nicer to support common image formats with a simple library.

stb also implements a 2D rectangle packer: stb_rect_pack.h I added this file in the project in order to compare my implementation to another one.

3rd party libraries

I use 2 external libraries for better visualization:

stb files (for PNG)
raylib (for GUI)

I don't rely on them for the algorithm implementation and the core of the exercise doesn't rely on external libraries.
