cpp 考点: 线段树 题解: 线段树为二叉树,如果查询区间位于当前区间之中,返回max值即可,如果超出范围,返回极小值即可,继续向左右搜索。 /** * DefinitionofSegmentTreeNode: * class SegmentTreeNode { * public: * intstart,end,max; * SegmentTreeNode *left, *right; * SegmentTreeNode(intstart, intend,...
I have created this structure successfully some weeks ago, and I want to share it with you. This structure isfast, efficient, and it is only the improvement from segment tree. I have used this code to submit to two problems, one is in SPOJ, one is in CF. For simpliest example, consi...
In bottom-up segment tree, we find the node corresponding to the leftmost element of the query, i.e. $x[l]$, and the node corresponding to the rightmost query element, i.e. $x[r]$. If we numerate nodes in a special way, the leftmost element will correspond to node $N+l$ and ...

我花了几天打算自己写一个zero-copy的版本, 使用boost里现成的managed_shared_memory和interprocess_semphore, container/vector等库, 但压力测试一直有问题, 有的传100多笔数据就出错,有的500多笔数据出错, 都是boost低层的rbtree之类的内存布局出错,调不下去,所以放弃自己写,而寻找开源的实现。

build_tree query modify 建树: 线段树将每个长度不为1的区间划分成左右两个区间递归求解,把整个线段划分为一个树形结构,通过合并左右两区间信息来求得该区间的信息。这种数据结构可以方便的进行大部分的区间操作。 使用结构体存储节点: cpp // C++ VersionstructNode{intl, r;// 其他属性值(sum,懒惰标记...)}...
