Solution: Binary Tree Paths
Explore how to apply backtracking to find all paths from the root to leaf nodes in a binary tree. This lesson guides you through recursive traversal, building path strings, and managing the recursion stack to capture every unique root-to-leaf route. Understand the time and space complexity involved, and gain the skills to implement this approach confidently.

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.
