题目链接:Permute K times 首先我们考虑暴力的作法,就是将一个点走k步,最后所在的那个点即为所求,考虑数据范围显然不可以,因此我们可以采用倍增的写法去实现。每个点的步数转化成二进制形式去求,用st表。 代码: #include <bits/stdc++.h>#define int long long#define fi first#define se secondusi

L ( x ) = ( 1 2 x H A x − b H x ) 2 , x ∈ C n × 1 L(x) = (\frac{1}{2}x^HAx-b^Hx)^2, x\in C^{n \times 1} L(x)=(21xHAx−bHx)2,x∈Cn×1是凸的 已知: L ( x ) = ( 1 2 x H A x − b H x ) 2 , x ∈ C n × 1 L(x) =
Now you have a string consists of uppercase letters, two integers AA A and BB B. We call a substring wonderful substring when the times it appears in that string is between AA A and BB B ( A≤times≤BA
