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. WebSep 20, 2015 · Root to leaf path sum equal to a given number Given a binary tree and a number, return true if the tree has a root-to-leaf path such that adding up all the values along the path equals the given number. Return false if no such path can be found. I have written 3 solutions: one recursive, one using 2 stacks (DFS), and last one using 2 queues (BFS).
