题目链接 可以贪心写,先把b数组按从小到大的顺序排个序,根据b[i]的值来产生a[n+i] 借助一个c数组,c[i]记录,j从i到n,a[j]-j的最大值,再加上一个实时更新的变量ma,记录从n+1到当前之前的a[n+i]-(n+i)的最大值,每次把max(c[b[i]],ma)的值赋给a[n+i] #include<bits/stdc++.h> using namespace std; typedef long long LL; ; ; int n; int a[N],b[N],c[N];…
题意 在一颗有点权的树上,选若干个点,使得这些点两两距离大于k,且点权和最大 思路 贪心的取比较大的值即可 将所有点按照深度从大到小排序,如果当前点点权\(a[i]\)大于0,则将距离为k以内的所有点减\(a[i]\) 代表取了当前点,为答案贡献\(a[i]\) 如果下面又扫到大于零的点权,说明那个点比这个大,于是取那个 复杂度\(O(n^2)\) 代码 int n,k; int a[maxn],b[maxn]; vector<int>v[maxn]; int ans; int dep[max…
