Bottleneck: The brute-force bottleneck this module eliminates — see M4.1-backtracking-decision-trees/README.md.
Pre-launch
This module is still in the pre-launch phase.
This site is a YC preview. Only M0.1 — memory boxes and the 10^8 ops/sec clock — ships video, audio, the quiz, and the toy. M4.1 stays on the syllabus so the map is honest; the filmed lesson is not in this build.
