All Nodes Distance K in Binary Tree

You are given a binary tree whose node values are all distinct, a node named target, and an integer K. Return the values of every node located exactly K edges away from target. Note: You may return the resulting values in any sequence. Example Input: Output: [7,9,14] Constraints The input tree contains at least one node. A node's distance from target is the count of edges on the path from target to that node. The tree contains fewer than 500 nodes. No two nodes in the tree…
