我们考虑最左边的那条链为最终链,那么对于一个点,他改变一定是改变到最左边那条链,而改变的上限就是sum−dep[now]+1sum−dep[now]+1,而sumsum就是那条最终链的长度。 Code #include<bits/stdc++.h>using namespacestd;inlinelonglongread(){longlongx=0,f=1;charch=getchar();while(!isdigit(ch)&...

【文文殿下】CF1098C Construct a tree 题解 题解挺水的一道题. Rating 23002300 以下送命题。首先我们知道,所有子树大小之和就是节点个数加上从根到所有节点的路径长度之和。他要求度数尽可能小,所以我们二分度数kk.显然,度数越小,子树和越大。对于一个kk叉树,他的子树大小之和为n+k2+k3+...+remn+k2+...
CF1098C Construct a tree Solution 首先,我们考虑二分答案,先算出这个分支系数最小是多少,但难点就在于如何判断,首先我们知道,如果不考虑分支系数,$ s $ 的最小值为 $ 2\times n -1 $ ,最大值为 $ \frac{n\times(n-1) }{2} $ ,而前者的分支系数为 $ n-1 $ 后者的分支系数为 $ 1 $,一种...
