判断hasNext(), 就判断index是否 >= arrayList.size() 就行了。 然后有点麻烦的地方,就是如果root = null。 怎么办。 然后我学习到了, 原来构造函数中,也可以使用return ** 总结: inorder BST 出来的数列是从小到大排列的。 构造函数中可以使用 return ...
The B-tree is a generalization of a binary search tree in that a node can have more than two children. According to Knuth's definition, a B-tree of order m is a tree which satisfies the following properties: Every node has at most m children. Every non-leaf node (except root) has ...

Thus, it is a data structure which is a type of self-balancing binary search tree. The balancing of the tree is not perfect but it is good enough to allow it to guarantee searching in O(log n) time, where n is the total number of elements in the tree. The insertion and deletion ...

Given a binary search tree (BST), find the lowest common ancestor (LCA) of two given nodes in the BST.According to the definition of LCA on Wikipedia:“The lowest common ancestor is defined between two nodes p and q as the lowest node in T that has both p and q as descendants (wher...
