学习线段树第二天,这道题属于第二简单的线段树,第一简单是单点更新,这个属于区间更新. 区间更新就是lazy思想,我来按照自己浅薄的理解谈谈lazy思想: 就是在数据结构中,树形结构可以线性存储(线性表)也可以树状存储(链表) 树形typedef struct node { int data; struct node* Lchild; struct node* Rchild; }Btree,*BTree;BTree = (BTree)malloc(Btree);好像是这样吧...大半个暑假过去忘得…

Problem Description In the game of DotA, Pudge’s meat hook is actually the most horrible thing for most of the heroes. The hook is made up of several consecutive metallic sticks which are of the same length. Now Pudge wants to do some operations on t…

题解: 和hdu1166敌兵布阵不同的是 这道题需要区间更新(成段更新). 单点更新不用说了比较简单,区间更新的话,如果每次都更新到底的话,有点费时间. 这里就体现了线段树的另一个重要思想:延迟标记. 在定义树节点结构体的时候加一个标记:flag. typedef struct node { node():l(0),r(0),data(0),flag(0){} //构造函数 初始化数据成员 int l,r; int data; //每个节点的数据 int flag; //延迟标记 }TNode;…

hdu1698 Just a Hook 题意:O(-1) 思路:O(-1) 线段树功能:update:成段替换 (由于只query一次总区间,所以可以直接输出1结点的信息) 题意:给一组棍子染色,不同的颜色有不同的值,执行一系列的区间染色后,问这组棍子的总值是多少. #include <cstdio> #include <algorithm> using namespace std; #define lson l , m , rt << 1 #define rson m…
