# Problem Challenge 2: Path with Maximum Sum (hard)

## Problem Statement

Find the path with the maximum sum in a given binary tree. Write a function that returns the maximum sum.

A path can be defined as a **sequence of nodes between any two nodes** and doesn’t necessarily pass through the root. The path must contain at least one node.

**Constraints:**

- The number of nodes in the tree is in the range [1, 3 * 10<sup>4</sup>].
`-1000 <= Node.val <= 1000`
