---恢复内容开始--- 题意:给定区间,每个人的成绩, Q次询问,求每次询问区间中的最大值 思路:构造线段树 代码: #include<stdio.h> #include<algorithm> #include<string> #include<iostream> using namespace std; int n, m, ans; string str; struct Tree { int left, right, maxx; }tree[ * ];…

这个也是线段树的经验问题,待修改的,动态询问区间的最大值,只需要每次更新的时候,去把利用子节点的信息进行修改即可以. 注意更新的时候区间的选择,需要对区间进行二分. #include<iostream> #include<stdio.h> #include<string.h> #include<algorithm> using namespace std; ; int b[maxx]; struct node{ int l; int r; int mid;…

注意点:scanf中使用%c时,会读取空格和回车,所以在%c之前要有一个空格 ( 或者直接使用%s也行,%s会忽略空格和回车 ).具体见下面的代码: #include<iostream> #include<vector> #include<string> #include<cmath> #include<set> #include<algorithm> #include<cstdio> #include<map>…
