My very-slightly-different Python implementation runs in 9m56s minutes on Python 3.11, but in 2m54s using pypy3.9 (all on an M1 Max) pypy never ceases to amaze

My very-slightly-different Python implementation runs in 9m56s minutes on Python 3.11, but in 2m54s using pypy3.9 (all on an M1 Max) pypy never ceases to amaze me for low-effort performance gains on computational stuff. A naive implementation in C compiled with Apple's clang (-O2) takes 0.62 seconds, of course.
