CF 105819L - Robot Racing

We have a non-decreasing array of robot speeds. For every contiguous segment of this array, we want to know the maximum number of groups the robots can be split into so that the groups can be stopped one by one before any robot travels beyond a track of length L.

CF 105819K - Not Japanese Triangle

We only know the last row of a triangular array. Every value above it is defined recursively as the minimum of the two values directly below it. If the last row is $$b1,b2,dots,bn$$ then the row above it contains $$min(b1,b2),min(b2,b3),dots$$ and the process continues upward.

CF 105819I - Cell Towers

We are given a set of houses on an infinite grid. A tower placed at a position (r, c) can serve every house that is not to the west of it and whose value row + column is not larger than the tower's row + column. The cost of building a tower is its row number.

CF 105819B - Sacrifice The Rook

We are playing a simplified chess endgame on an 8 by 8 board. We control a king and a rook, while the opponent controls only a king. The question is whether we can make exactly one legal move so that on the opponent's next turn their king can capture our rook legally.
