[atABC288Ex]A Nameless Counting Problem 记f(n,m,x)f(n,m,x)为满足⎧⎪⎨⎪⎩ai∈[0,m)⨁ni=1ai=x∀i≠j,ai≠aj{ai∈[0,m)⨁i=1nai=x∀i≠j,ai≠aj的序列{an}{an}数,则答案即∑0≤i≤⌊n2⌋(m+i−1i)f(n−2i,m+1,x)(n−2i)!∑0≤i≤⌊n2⌋...
翻译官方题解。 一 考虑Ai≤Ai+1Ai≤Ai+1 这个条件可以将序列与可重集构成一组双射。问题就是计算包含 NN 个≤M≤M 的数的可重集 AA 的个数使得 xor 和为 XX.而考虑一个值只有出现奇数次才会产生贡献,那么对这个进行计数,再算一下剩下偶数次的贡献即可。 具体地,令 gLgL 为LL 个≤M≤M 的两两不...

Nameless subcommands function a similarly to groups in the main App. See Option groups to see how this might work. If an option is not defined in the main App, all nameless subcommands are checked as well. This allows for the options to be defined in a composable group. The add_...
