Solution: Binary Tree Paths

Learn how to implement a backtracking algorithm that traverses a binary tree to record all paths from the root to each leaf. This lesson guides you through building the path strings, handling recursion effectively, and understanding the time and space complexities involved in exploring tree structures.

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 ...
