Solution: Binary Tree Paths
Explore how to use backtracking to traverse a binary tree and collect all root-to-leaf paths as strings. Learn to implement a recursive solution that builds paths dynamically, handles leaf nodes, and backtracks to explore all branches while understanding the associated 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.
