113. 路径总和 II
中等

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 = [1,2,3], targetSum = 5
输出:[]

示例 3:

输入:root = [1,2], targetSum = 0
输出:[]

 

提示:

    树中节点总数在范围 [0, 5000] 内
    -1000 <= Node.val <= 1000
    -1000 <= targetSum <= 1000
