Solution: Binary Tree Paths
Explore how to solve the binary tree paths problem by applying backtracking to traverse from root to leaf nodes. Understand the recursive method for building and recording each path as a string, and analyze the time and space complexity involved in the 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.
