二叉树查找树中序后继 · Inorder Successor in Binary Search Tree

[抄题]:

给一个二叉查找树以及一个节点,求该节点的中序遍历后继,如果没有返回null

[思维问题]:

不知道分合算法和后序节点有什么关系:递归的终止条件就是后序节点是否为空。

[一句话思路]:

[输入量]:空: 正常情况:特大:特小:程序里处理到的特殊情况:异常情况(不合法不合理的输入):

[画图]:

[一刷]:

  1. 不要写inorderSuccessor(root, root.left),因为完全就是错的。root是不能和自己递归的。所以不一定要定义left.

[二刷]:

[三刷]:

[四刷]:

[五刷]:

[总结]:

[复杂度]:Time complexity: O() Space complexity: O()
