给定两个整数数组 inorder
和 postorder
,其中 inorder
是二叉树的中序遍历, postorder
是同一棵树的后序遍历,请你构造并返回这颗 二叉树 。
示例 1:
输入:inorder = [9,3,15,20,7], postorder = [9,15,7,20,3] 输出:[3,9,20,null,null,15,7]
示例 2:
输入:inorder = [-1], postorder = [-1] 输出:[-1]<iframe allowfullscreen="true" data-mediaembed="bilibili" frameborder="0" id="93OYiniP-1717120386080" src="https://player.bilibili.com/player.html?aid=112532171064833"></iframe>
