WebGiven a binary tree and a sum, find all root-to-leaf paths where each path’s sum equals the given sum. Note: A leaf is a node with no children. 解答： 本题为 LeetCode 112 题的进阶版。通过 DFS 深度优先搜索，找到满足的路径。在这种寻找不唯一路径的题目中，用到了之前多次用过的递归回溯的方法 WebMay 2, 2024 · Given the root of a binary tree and an integer targetSum, return all root-to-leaf paths where the sum of the node values in the path equals targetSum. Each path should be returned as a list of the node values, not node references. A root-to-leaf path is a path starting from the root and ending at any leaf node. A leaf is a node with no children. buds marine in ohio

This is due to the fact that we traverse each node once (which will take O (N)), and for every leaf node we might have to store its path which will take O (N). We can calculate a tighter time complexity of O (NlogN) from ... buds marshfield ma
