Solution: Binary Tree Paths
Understand how to apply backtracking to explore all root-to-leaf paths in a binary tree. This lesson teaches you to implement a recursive solution that builds path strings and records each complete path using depth-first traversal. You will also learn to evaluate time and space complexities for this approach.

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.
