这两个要求可以用同一种逻辑实现,即节点A的值大于等于节点B的值,则返回False。 因此我们使用中序遍历(In-Order Traversal),先左后中,先中后右,并确以该顺序遍历的值不断增大。一旦没有增大,立刻返回False,不然继续以此顺序遍历至None节点返回。 对于一个节点来说,其左子树先于它给cur_max赋值,它先于右子树给...

094.binary-tree-inorder-traversal Given a binary tree, return the inorder traversal of its nodes' values. For example: Given binary tree [1,null,2,3], 1 \ 2 / 3 return [1,3,2]. Note: Recursive solution is trivial, could you do it iteratively?
Given a binary tree, return theinordertraversal of its nodes' values. 示例: 代码语言:javascript 代码运行次数:0 AI代码解释 输入:[1,null,2,3]1\2/3输出:[1,3,2] 进阶:递归算法很简单,你可以通过迭代算法完成吗? Follow up:Recursive solution is trivial, could you do it iteratively?
