re: branch cuttingIDK if this is what your issue was, but one thing I ran into was that if you do something like if (current_total >= target) prune(), this can be problematic because if the tail end of the data is 0s and 1s, you exit too early. Basically I would prune strictly when the current total > target.

re: branch cutting

thanks for the tip, I looked into it again and I found I was cutting in the wrong place. Fixed now, and halves the time for part 2
