Fliptile 题目大意:农夫想要测牛的智商,于是他把牛带到一个黑白格子的地,专门来踩格子看他们能不能把格子踩称全白 这一题其实就是一个枚举题,只是我们只用枚举第一行就可以了,因为这一题有点像开关一样,一个翻了,另一个就要跟着一起翻,第一行会影响下面所有行,而且影响情况只有一种,所以枚举完了以后我们不断模拟就可以了 #include <iostream> #include <functional> #include <algorithm> using namespac…

考试想到了状压,苦于T1废掉太长时间,于是默默输出impossible.. 我们知道,一个格子的翻转受其翻转次数和它相邻翻转次数的影响. 由每一个位置操作两次相当于把它翻过来又翻回去,所以答案中每一个点操作次数为0或1. 然后我们枚举第一行的状态,1代表翻转,0代表不翻转. 如果与它相连的点的操作次数和它本身状态之和为偶数,它就会被翻成白色. 由于我们从上向下推,所以对于上一行的点来说,只有它下面那一个点不确定,我们就让下面这一个点进行能够让上一行点满足全为白色的操作. 这样推到最后一行,前面m…
