Step-By-Step Directions From a Binary Tree Node to Another You are given the root of a binary tree with n nodes. Each node is uniquely assigned a value from 1 to n. You are also given an integer startValue representing the value of the start node s, and a different integer destValue representing the value of the destination node t. Find the shortest path starting from node s and ending at node t. Generate step-by-step directions of such path as a string consisting of only the uppercase letters 'L', 'R', and 'U'. Each letter indicates a specific direction: 'L' means to go from a node to its left child node. 'R' means to go from a node to its right child node. 'U' means to go from a node to its parent node. Return the step-by-step directions of the shortest path from node s to node t. Input: root = [5,1,2,3,null,6,4], startValue = 3, destValue = 6 Output: "UURL" Explanation: The shortest path is: 3 → 1 → 5 → 2 → 6. Input: root = [2,1], startValue = 2, destValue = 1 Output: "L" Explanation: The shortest path is: 2 → 1.
