E - Tunnel Warfare HDU - 1540 对这个题目的思考:首先我们已经意识到这个是一个线段树,要利用线段树来解决问题,但是怎么解决呢,这个摧毁和重建的操作都很简单,但是这个查询怎么查呢, 这个是不是要判断这一个点左边和右边最远的距离,然后相加起来就可以了,所以就是维护一个区间最左边和最右边的值,然后把他们合并就是最大值. 这个最左边的值 pre_max = 子左节点的 pre_max 如果这个 pre_max==len 那就可以合并子右节点的 pre_max 最右值同理 这个…

Problem地址:http://acm.hdu.edu.cn/showproblem.php?pid=1079 一道博弈题.刚开始想用判断P点和N点的方法来打表,但无奈不知是哪里出错,总是WA.于是看了该题的Discuss,才明白这种做法. 日子到日子之间会存在这种变化:假设初始为a月b日,且sum = a+b,则进行一次变化后即为sum = a+b+1,即奇偶性会改变. 可以发现11月4号是11+4=15,也就是奇数.那么当一开始Adam得到的和为偶数时,那么Adam就有方法将偶数变为奇数.…

题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=1079 题目大意:给你一个日期(包含年月日),这里我表示成year,month,day,两人轮流操作,每次操作可以将month+1但是,如果下月没有对应的day则只能对day+1(超过该月日数就进入下月一日),或者就day+1.谁最后到达2001.11.4这个日期就是胜者,问先手的人是否能获胜. 解题思路:这个就用上面的P/N分析,一个个月份日期对应的标记上P或N(很快会发现规律只用找每月特定几天),…
