at first I was trying to extend my
Solution to problem 1
Which consists of passing a value to a funnel that is the vector whose elements are maps.
That would mean iterating one-by-one over seed ranges. Obviously this is too slow.
but then I deviated and started trying to redo the solution to problem 2 from scratch, at one point thinking about using a

custom tree based solution.
But my laziness won and I went back to my problem 1 solution and extended it there. Like you, faced off-by-one errors caused by not reading the problem statement properly.
