剑指Offer——从上到下打印二叉树III（JS实现）｜刷题打卡

前言掘金团队号上线，助你 Offer 临门！点击查看详情题目描述解题思路这道题属于二叉树的层次遍历问题首先定义三个数组数组queue用来存放当前层的所有元素指针数组temp充当临时数组，用来存放当前元素所有指针的左右孩子指针数组test用来存放每一层元素的值当test存储完一层的元素后，就将queue置为空，然后遍历temp将每个元素的左右孩子节点继续放入queue，继续下次循环解题代码va....

剑指Offer——从上到下打印二叉树（JS实现）

题目描述解题思路使用队列来存储同一层的元素使用数组1来存放同一层元素的所有值使用数组2来存放用一层元素的所有指针将数组1放进结果列表将数组2所有元素的左右孩子放进队列，当队列的长度不为零的时候继续循环。实现代码var levelOrder = function (root) { // 如果系统给的根元素为空，直接返回 if (!root) return []; // 定义...
