"WebOct 20, 2016 · @Eli: the impression depends on phrasing. Asked "sum the nodes in a binary tree", saying "in C++ the STL's std::map<> is the Standard's binary tree; using its public interface a simple, general way to sum nodes is XXX. It's equally applicable to other iterator-sporting abstractions." then I think that would be a sound answer. " - Pair sum binary tree github

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. 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. Websum = 7 Output: Pair with the given sum (1,6) Explanation: We will store the node of the tree in a set while traversing. If, for present node 1, there exists a node for which the sum of both nodes is equal to the target node, then we will return the pair. Example 2: Input: sum = 13 Output: Pair with the given sum (5,8) Explanation:
