Solution: Binary Tree Paths
Explore how to use backtracking to traverse a binary tree from root to leaf nodes, collecting all unique paths as strings. This lesson helps you understand the recursive process, manage path strings, and analyze the algorithm's time and space complexities.

Statement
Given the root of a binary tree, return all paths from the root to the leaf nodes in any order. Each path should be represented as a string of node values, separated by arrows (→), where a leaf is defined as a node with no children.
