Solution: Binary Tree Paths

Explore how to identify all root-to-leaf paths in a binary tree by applying backtracking techniques. This lesson helps you understand recursive traversal, path building, and how to track routes efficiently, improving your skills in solving tree-based coding interview questions.

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 ...
