Description Heavy rain struck dairy farms. farm is a rectangle of R * C, where 1 ≤ r, c ≤ 50. heavy rain makes the land without long grass muddy, but the careful cows don't want to dirty their shoes while grazing. to prevent their shoes from getting dirty, John decided to put some boards in the muddy pasture. the width of each Board is 1 unit and the length is arbitrary. each board must be placed in the mud

1/* 2. Use a wooden board to cover the muddy place and not the grass. Any length of wood! Overlapping overwrites are allowed! '*' Indicates the muddy place, '.' indicates the grass! 3 train of thought: 4 first let's recall the HDU 2119 matrix question.

Assume that ANS is to be determined, we can change the edge weight of each edge to s [I] [J]-ans * t [I] [J], then run the longest path. If d [N]> = 0, it indicates that this ANS is

Enhanced version 3041 Because the lawn cannot be covered by wooden boards, you need to deal with it more. Since the wooden boards can only be placed horizontally or vertically, the first time the numbers of boards that can be placed horizontally and are not consecutive, and the second time the numbers of boards that can be placed vertically and are not consecutive Think of a wooden board as a vertex and a muddy ground as an edge.
