Solution: Binary Tree Paths

Explore how backtracking helps traverse binary trees to list all root-to-leaf paths as strings. This lesson guides you through implementing the solution, understanding the recursion, and analyzing time and space complexity in the context of coding interviews.

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.

Constraints:

  • 11\leq nodes 100\leq 100 ...
