Solution: Binary Tree Paths
Explore how to solve the binary tree paths problem by applying backtracking. Learn to traverse from the root to each leaf node, building path strings along the way, and backtrack to cover all paths. Understand the algorithm's time and space complexity as you implement a clear, recursive solution.

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.
