BZOJ3569 : DZY Loves Chinese II

这回是真·强制在线了，首先这道题就是AHOI2013连通图的加强版，那道题k最大只有4 那道题的做法是： 取一个生成树，对每条非树边取一个随机权值， 对每条树边设为“覆盖它的所有非树边”的权值的xor， 对于每次询问，只要某个子集的所有边xor值是0，那么就不连通，否则连通。 通过$O(2^k)$枚举每一个子集来判断，复杂度为$O(q2^k)$ 这道题也是一样的方法，但是

注意到集结操作相当于合并一些点 于是我们可以使用并查集 对于每一行、每一列维护一个链表，储存里面的点 查询x时，在并查集中找到x的祖先u，此时x的坐标就是u的坐标 然后扫描u所在行列的链表，依次删除每个点，并把这些点合并成一个新点，同时计算贡献 对于修改操作，可以看作是分离，新建一个点代表修改后的点，然后对于原来的点减掉贡献即可   #include<cstdio&
