Chapter 10 on search methods postponed discussion of binary search directories which may vary dynamically. We shall now remedy that omission. To calculate the average search length of a binary search the set of possible paths through the directory was represented by a binary tree (figure 13.1).doi:10.1007/978-1-349-15981-9_13Derek Coleman
我们在使用有序的LinkedListSet时,如果要寻找一个值,通常会使用for loop,需要linear time,是否有一种方法提高搜索的效率?因此产生了Binary search trees. Binary search trees,从中间值切入,若中间值比目标值小,则往右;若中间值比目标值大,则往左。 首先回顾一下原始的Rooted trees. rooted trees 除了root以外的每...
In order to move subtrees around within the binary search tree ,we define a subroutine Transplant ,which replaces one subtree as a child of its parent with another subtree. With the transplant procedure in hand ,here is the procedure that deletes node z from binary search tree T :...

Also, considering the root node withdata=5, its children also satisfy the specified ordering. Similarly, the root node withdata=19also satisfies this ordering. When recursive, all subtrees satisfy the left and right subtree ordering. The tree is known as a Binary Search Tree or BST. ...
Binary Search Trees(BST) BST的性质 BST的形状为 每个BST中的节点x,存在一个key,一个指向父节点的parent指针,同时还有一个左子树和右子树 root的parent不存在 左子树值y与父节点x满足 key(y) <= key(x),右子树z满足 key(x) <=key(z) 插入实现机制...
