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,...

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...)}...
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 ...
AVL treeto balance tree. Magiccally, the addtional functions arevery independentwith our old code. Here is some functions we need to add, it is not different from AVL tree: intlink(intll,intu,intrr){Left[u]=ll,Right[u]=rr;returnupdate(u),u;}intright_rotate(intu){intll=Left[u]...
