    Now that SRM813 is behind us, I have a question about a particular DivII problem call LightBulbRow.

    The editorial on SRM813, by its author @misof, is here.

    I am interested in how I might find an optimal solution to this problem: that is, how to find the sequence that solve the problem in the fewest possible moves. All I can think of is exhaustive search...hence my post here.

    Any thoughts? Thanks in advance!
