Reference answers with reasoning. Try the ../exercises/ yourself first - the learning is in the struggle, not the answer key.

This directory has its own Makefile:

make all GPU_ARCH=gfx950      # build every solution for your GPU
make run                      # build + run all; every one must PASS
make clean
