题意 给你一个长度为\(n\)的序列和一个数\(m\). 小A和小B分别在\([1,m]\)选出一个数\(a\)和\(b\),然后开始游戏. 轮到小A时,他选择一个元素减\(a\):小B则选择一个元素减\(b\). 不能将元素变成负数. 问对于所有\(m \times m\)对\((a,b)\),分别有多少对是小A/B必胜,先/后手必胜. $ n \leq 100,m \leq 100000 $,序列元素 $ \leq 10^{18} $ 思路 首先易知,原序列与原序列\(mod \space…

[ARC119F] AtCoder Express 3 [ARC117F] Gateau 考虑二分答案,对前缀和建差分约束 \(\text{check}\) ,但是用 \(\text{spfa}\) 判断负环是 \(O(n^2)\) 的,妥妥地 \(\text{TLE}\) 掉.仔细观察这张图,实际上它是很有规律的: 这是在一条链的基础上给 \(i\) 和 \(i+n\) 连了一条双向边,我们从 \(2\times n\) 向 \(n\) 扫,同时考虑 \((i)\to (i-n)\to (i-…
