  • pare_down ๐Ÿ”’
    Pare down is used as a step in the LUB computation. It edits the candidates array in place by removing any element j for which there exists an earlier element i<j such that i -> j. That is, after you run pare_down, you know that for all elements that remain in candidates, they cannot reach any of the elements that come after them.
