Can you solve this real interview question? All Nodes Distance K in Binary Tree - Given the root of a binary tree, the value of a target node target, and an integer k, return an array of the values of all nodes that have a distance k from the target node
Error: Do not fully understand the BFS, when wants to get smallest distance, or K distance, it is very useful to think about it.
