This is a project in which we learned about the details, advantages, and disadvantages of using trees as data structures. We learned about how to qualify trees as well as how to traverse them. Throughout the pr
Splay tree:A splay tree structure refers to a self-balancing binary search tree that gets rearranged (or "splayed") so that recently accessed elements can be quickly accessed again. T-tree:A self-balancing tree structure optimized for databases that keeps both data and index in memory. Heap ...
一般化的二叉查找树(binary search tree) “矮胖”,内部(非叶子)节点可以拥有可变数量的子节点(数量范围预先定义好)应用大部分文件系统、数据库系统都采用B树、B+树作为索引结构 区别B+树中只有叶子节点会带有指向记录的指针(ROWID),而B树则所有节点都带有,在内部节点出现的索引项不会再出现在叶子节点中。 B+树...
Heap.A heap is a tree-based structure in which each parent node's associated key value is greater than or equal to the key values of any of its children's key values. Graph.A graph stores a collection of items in a nonlinear fashion. Graphs are made up of a finite set of nodes, a...
run a vector search. There are many poor tradeoffs for this such as speed, accuracy, filtering, and heap sorting. These so-called dual systems suffer because the vector databases often don’t have the same (or any) filtering capabilities so they return massive amounts of information that’s...
Can Struct stored in heap?! can VB & C# to be used in same project? Can we add derived class object to base class object? Can we change the return type of a method during overriding in c# Can we const with String.Format Can we create multiple sql connection object from multiple thread...
A.stack B.queue C.tree D.graph 概念题 To build a heap from N records, the best time complexity is: A.O(logN) B.O(N) C.O(NlogN) D.O(N^2) Heapify 从最后一个非叶子节点一直到根结点进行堆化的调整。如果当前节点小于某个自己的孩子节点(大根堆中),那么当前节点和这个孩子交换。Heapify是...

The first is the classic n-way merge of n sorted runs using our own highly optimized heap implementation (e.g. no recursion). Note that there are no memory allocations since the result can be merged into the destination. The second approach, which we call a tree-Q merge, is a less ...
