    从顶层设计的角度考虑,我们并不关心具体的放置骨牌的方法,而只关心这种覆盖是否可行而一种覆盖可行等价于该覆盖中不存在“L型”于是我们就可以优化轮廓线DP的设计以省去DP中构造方案所需要的时空复杂度本题似乎还卡STL,下次涉及到大量入队出队操作的时候还是手写队列吧,毕竟也就

    题面传送门非常好题目!首先我们考虑两条线段\([l_1,r_1],[l_2,r_2]\)满足\(l_1\leql_2\leqr_2\leqr_1\),如果大的线段选了,那么小的是否选择都无所谓,这样贡献就抵消了。因此,我们可以把包含其它线段的线段去掉,就剩下了一堆不交的线段。然后考虑一个单次\(O(n)\)的DP做法:
