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),…

题目链接 此类博弈不需要考虑sg函数,只需要确定必胜态和必败态,解题思路一般为打败先打表找规律,而后找规律给出统一的公式.打表方式:给定初始条件(此题中为ok[0]=ok[1]=0),然后从低到高枚举某一状态的所有次态,若有存在必败次态,则当前状态为必胜态,否则当前状态必败. 题意:对单独一堆石子,支持两种操作:1.石子数-1:2.石子数变为原来石子数的某一因数.取走走后一堆或无法操作(面对n==0,坑啊..)者为负. 先打表找下规律 #include<bits/stdc++.h> using…
