CF1466I The Riddle of the Sphinx
### 基本思路 明示了在二进制下考虑问题,我们大体的思路就是从高往低依次确定最大的数二进制下每一位上的值。 以下所述的「前缀」均指一个二进制数从高位到低位的一部分,一个元素的「前 $k$ 位」表示二进制从高位到低位的前 $k$ 位,$res$ 表示当前记录的最大前缀的长度。 先看看操作能干嘛,一是 ......

Atcoder ARC058B Iroha and a Grid
考虑从第 $b$ 列与第 $b + 1$ 之间分开这个矩阵,钦定 $(i, b)$ 下一步必须走到 $(i, b + 1)$,可以发现这样是不会漏算或算重的。 于是就可以用乘法原理算出这个 $i$ 的贡献:$\binom{(i - 1) + (b - 1)}{i - 1}\times \binom{ ......
