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.

Constraints:

  • 11\leq nodes 100\leq 100 ...
