Solution: Binary Tree Paths

Explore the process of using backtracking to find all root-to-leaf paths in a binary tree. This lesson guides you through a recursive approach that builds and records paths, helping you understand tree traversal and path construction in C++.

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

  • 104-10^4\leq ...
