Binary tree path sum to target
WebGiven a binary tree and a sum, determine if the tree has a root-to-leaf path such that adding up all the values along the path equals the given sum. For example: Given the below … WebFor example: Given the below binary tree and sum = 22, 5 / \ 4 8 / / \ 11 13 4 / \ \ 7 2 1. return true, as there exist a root-to-leaf path 5->4->11->2 which sum is 22. Solution. if you reach to a node which is empty, which means there is no such path, when you reach to a leaf node, check wether it is a valid path. otherwise continue to next level.
