CF1523H Hopping Around the Array

首先考虑 \(k = 0\) 的情况。 贪心,最后一步之前每个 \(i\) 只会跳到 \(j \in [i, i + a_i]\) 且 \(j + a_j\) 最大的点 \(j\),这个信息或许可以线性处理?但是我没脑子,我用线段树维护,时间复杂度 \(\mathcal O(n \log n)\)。 ......

CF1511G Chips on a Board

不难发现这是个 Nim 游戏,于是对每对 \((L_i, R_i)\) 所求转化为: \[\bigoplus_{i = 1}^n (a_i - L_i)[a_i \ge L_i] \]暴力做时间复杂度就是 \(\mathcal O(n^2)\),考虑优化。 感觉好像可以倍增?设 \(f(i, k)\ ......
