思路:这题我是看了题目后,上百度搜了一下才知道还有求最大曼哈顿距离的方法.直接把代码copy过来,研读一下,知道了代码实现机制,自然就很容易想到用优先队列来维护每种状态下的xi,yi之和的最大值最小值,以及其属于哪个点.那么对于删点操作只需要标记为不存在就可以了.在队列出队时,若队顶元素不存在,就出队. #include <iostream> #include <cstdio> #include <cstring> #include <algorithm>…

这题难度颇大啊,TLE一天了,测试数据组数太多了.双向广度优先搜索不能得到字典序最小的,一直WA. 思路:利用IDA*算法,当前状态到达目标状态的可能最小步数就是曼哈顿距离,用于搜索中的剪枝.下次搜索的限制不能直接加1,会超时,应该从当前状态到目标状态最小限制开始搜索. AC代码 #include<cstdio> #include<cstring> #include<algorithm> #include<iostream> #include<cmat…

题意: 许多 k 维点, 求这些点之间的最远曼哈顿距离. 并且有 q 次操作, 插入一个点或者删除一个点. 每次操作之后均输出结果. 思路: 用"疑似绝对值"的思想, 维护每种状态下各点的计算值, 插入或删除一个点就更新一次每种状态(用 multiset 或 map 或 priority_queue 实现), 每次求ans时扫一遍最大差值即可. 为了练习STL, 每一个都实现一次. multiset /* ****************************************…
