上一个节点的next就得不到更新Question给你一个数组 nums 和一个值 val,
给你二叉树的根节点 root 和一个整数目标和 targetSum ,找出所有 从根节点到叶子节点 路径总和等于给定目标和的路径。 叶子节点 是指没有子节点的节点。 示例1: 输入:root = [5,4,8,11,null,13,4,7,2,null,null,5,1], targetSum = 22 输出:[[5,4,11,2],[5,8,4,5]] 示例2: 输入:root...

Can you solve this real interview question? Two Sum - Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target. You may assume that each input would have exactly one solution, and you may n
输入:g = [1,2,3], s = [1,1]输出:1解释:你有三个孩子和两块小饼干,3 个孩子的胃口值分别是:1,2,3。 虽然你有两块小饼干,由于他们的尺寸都是 1,你只能让胃口值是 1 的孩子满足。 所以你应该输出 1。 示例2: 输入:g = [1,2], s = [1,2,3]输出:2解释:你有两个孩子和三块小饼干,...
