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, *ri

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];...
This function is used to build a segment tree,with its parameters representing the index of 22 the root(num),the starting point of the total segment(left),and the ending point of the total 23 segment(right),respectively*/ 24 void Insert_Segment(int num,int left,int right,int...

Today, Segment Tree takes revenge on you. As Segment Tree can answer the sum query of a interval sequence easily, your task is calculating the sum of the sum of all continuous sub-sequences of a given number sequence. Input The first line contains a single integer T, indicating the number...
