在atcoder_testcases - Dropbox 即可查看每一题的输入输出文件。 来源atcoder 主页 用了三年第一次知道原来 atcoder 还可以看 testcase,全网却找不到任何一篇文章说明,并且任何 atcoder 的食用指南都没有提及,但我觉得这是作为一个 oj 最重要的部分,所以就有了这么一篇文章。 这个是我查 atcoder 评测机信息的...
考虑把给出的策略扔进四元幂级数里,然后做以下运算的卷积: \[x \otimes y= \begin{cases} x,x=y\\ 3,x \neq y \end{cases} \] 由FWT 理论,构造变换矩阵: \[\left[ \begin{matrix} 1 & 0 & 0 & 1\\ 0 & 1 & 0 & 1\\ 0 & 0 & 1 & 1\\ 0 & 0 & 0 & 1\\ \end{matrix...
记\(g(x)\) 表示\(x\) 个点随意连边的方案数,则: \[\begin{aligned} g(x) = \begin{cases} 0, & x \equiv 1\pmod{2} \\ \frac{x!}{\left( \frac{x}{2} \right)!2^{\frac{x}{2}}} = 1 \times 3 \times \dots \times (x - 1), & x \equiv 0\pmod{2} \\ \end{cas...
Maybe the test cases are too weak? And the test cases for ABC319 are't published yet (in fact, the latest public test cases from AtCoder is that of ABC311). → Reply silenttkillerr 18 months ago, # | 0 Can anyone give proof for E, how time taken for t1 and t2 will be...
