Problem: Binary Tree Paths

Medium
30 min
Explore how to use backtracking to generate all paths from root to leaf nodes in a binary tree. Learn to represent paths as strings and understand leaf nodes for coding interview problems.

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 nodes.data 104\leq10^4
