CF1890D Doremy's Connecting Plan

或许赛时根本不需要证明贪心的正确性。 我们发现 \(c\) 对于问题的影响不大,我们可以将每个 \(a_i\) 除以 \(c\),就转化为了 \(c=1\) 的情况。 一个自然的贪心是用 \(1\) 作为中心点去连接其他的所有点,这需要两条结论保证其正确性: 结论一: 如果当前图中还可以连边,点 \ ......

extern "C" __attribute__((constructor))

extern "C":这是 C++ 中的语法,用于指定一个函数或变量应该按照 C 语言的约定进行编译和链接。在 C++ 中,函数和变量的名称会根据其作用域和命名空间进行修饰,而这会导致无法和 C 语言中的函数和变量进行正确的链接。使用 extern "C" 可以避免这个问题,确保这个函数或变量的名称 ......

NOMURA Programming Competition 2020 D Urban Planning

考虑排列 \(P_i\) 已经固定了的情况,那么连边 \(i\to P_i\) 形成有向图 \(G\),最小连边数就是 \(N\) 减去弱连通块数。善良的出题人已经告诉你连边方案就是 \((N-1)^K\),所以答案就是 \(N(N-1)^K\) 减去所有连边方案中弱连通块数量总和。于是只需要考虑所 ......
