Solution: Binary Tree Paths

Explore how to solve the problem of finding all paths from the root to leaf nodes in a binary tree using backtracking. This lesson guides you through recursive traversal, path construction, and returning all root-to-leaf paths efficiently, helping you master this common interview coding pattern.

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 ...
