Can you solve this real interview question? Find a Corresponding Node of a Binary Tree in a Clone of That Tree - Given two binary trees original and cloned and given a reference to a node target in the original tree. The cloned tree is a copy of the ori
You are given a binary tree in which each node contains an integer value. Find the number of paths that sum to a given value. The path does not need to start or end at the root or a leaf, but it must go downwards (traveling only from parent nodes to child nodes). The tree has ...
