Both the left and right subtrees must also be binary search trees. 代码: /** * Definition for a binary tree node. * struct TreeNode { * int val; * TreeNode *left; * TreeNode *right; * TreeNode(int x) : val(x), left(NULL), right(NULL) {} * };*/classSolution {public:bool...

使用binary search tree 做为 priority queue 的底层机制,元素的插入和极值的取得就有 O(logN) 的表现。但是这需要确保输入数据的随机性。priority queue 的复杂度,最好介于 queue 和 binary search tree之间,才算适得其所。binary heap 便是这种条件下的适当候选人。

许多的小球一个一个的从一棵满二叉树上掉下来组成FBT(Full Binary Tree,满二叉树),每一时间,一个正在下降的球第一个访问的是非叶子节点。然后继续下降时,或者走右子树,或者走左子树,直到访问到叶子节点。决定球运动方向的是每个节点的布尔值。最初,所有的节点都是FALSE,当访问到一个节点时,如果这个节点是FALSE...
