Sometimes I encounter a type of range queries that I don't know how to do using segment tree, so I use a merge sort tree instead. It can answer queries in O(log2n)O(log2n). I decided to share this because it can
1) That's the whole point of a Segment tree / Merge sort tree. You don't want to go down the tree. Because at the bottom of the tree there arennodes. And you want to answer queries in less thanO(n)time. By using the conditionx <= l && r <= yyou are guaranteed that you on...

tree sort直接拿以前笔试试卷上的二叉树题目做,所以带了模版。没有平衡,效率不太好(0.02s过)去掉插入操作里的检查重复元素之后就可以允许重复元素了。 #include <iostream>#include<stack>usingnamespacestd; template<classEntry>structBinary_node { Entry data; ...

ClickHouse 当前实现为 Heap merge,示意图如下。源码注释中可以看到想要切换为 Loser Tree,但还没有实现。 两种Merge 算法: Horizontal 与 Vertical Merge 过程本身是针对主键的,对于非主键字段,可以选择以下两种处理方式: Horizontal: 在主键进行 Merge 时,其他非主键字段也同时连带写入结果集,直接完成 Merge ...
Note that Patience+ sort is already a dramatic improvement over Patience sort, bringing the execution time difference w.r.t. Quicksort down from 10x-20x to 1.5x-2x. Somewhat reassuring is that the tree-Q Patience+ sort seems to mostly eliminate the deterioration compared to Quicksort as ...
類型: MERGE_UPDATE_STATUS* 當這個方法傳回時,會包含下列其中一個值的指標,指出合併進程的狀態。 MUS_COMPLETE 表示進程已順利完成。 MUS_USERINPUTNEEDED 表示使用者需要額外的輸入,才能完成此程式。 MUS_FAILED 表示進程失敗。 傳回值 類型: HRESULT 如果此方法成功,則會傳回 S_OK。 否則,它...
