题目:给你一个数字问将他写成连续的数字的和的形式.有几种写法. 分析:数论. 设拆成的序列个数为k,我们分两种情况讨论: 1.拆成奇数个连续数.那么设中位数是a,则有n = k * a: 2.拆成偶数个连续数,那么设中位数是a与a+1,则有n = k / 2 *(a+a+1). 综上所述,本问题就是将n拆成2个数的乘积的形式,且当中一个一定为奇数: 问题转化成求解n中奇数因子的个数.这里求出全部的奇素因子计算组合数就可以. 说明:实际的数据规模没有题面上那么大╮(╯▽╰)╭. #include…

You are given a binary tree in which each node contains an integer value. Find the number of paths that sum to a given value. The path does not need to start or end at the root or a leaf, but it must go downwards (traveling only from parent nodes to…

题面 题意 给出一张\(n\)点\(m\)边无向连通图,求每条边出现在多少个割集中. \(n\le20,m\le\frac{n(n-1)}{2}\) sol 所谓割集,就是指把\(n\)个点分成两个集合后,两个集合分别都是连通的. 所以我们可以预处理出每一个点集是否连通. 考虑边\((u,v)\).实际上\((u,v)\)要出现在割集中,\(u,v\)就必然在不同的点集中. 来一波总方案减不合法. 所有可行的割的方案减去\(u,v\)在同一个割集里面的方案. \(u,v\)在同一个割集里面的方案…
