题目地址:POJ 3468 打了个篮球回来果然神经有点冲动. . 无脑的狂交了8次WA..竟然是更新的时候把r-l写成了l-r... 这题就是区间更新裸题. 区间更新就是加一个lazy标记,延迟标记,仅仅有向下查询的时候才将lazy标记向下更新.其它的均按线段树的来即可. 代码例如以下: #include <iostream> #include <cstdio> #include <cstring> #include <math.h> #include &l…

#include <iostream> #include <stdio.h> #include <string.h> #define lson rt<<1,L,mid #define rson rt<<1|1,mid+1,R using namespace std; ; int n,q; long long num[maxn]; struct Node{ long long sum,add; bool lazy; }tree[maxn<&l…

#include<iostream> #include<string> #include<algorithm> #include<cstdlib> #include<cstdio> #include<set> #include<map> #include<vector> #include<cstring> #include<stack> #include<cmath> #in…

伸展数最基本操作的模板,区间求和,区间更新.为了方便理解,特定附上一自己搞的搓图 这是样例中的数据输入后建成的树,其中的1,2是加入的边界顶点,数字代表节点编号,我们如果要对一段区间[l, r]进行操作,只需要把第l-1位的数旋转到0节点下面,把r+1位的数旋转到当前的root下面,就如上图所示,那么椭圆里表示的就是区间[l, r]. 附上注释代码.指针版本的比静态数组的快1s多.. /* ********************************************** Author…
