Binary Tree Maximum Path Sum is an example of tree problems. In this post we will see how we can solve in Javascript.

Problem Description

Given a binary tree, find the maximum path sum. For this problem, a path is defined as any sequence of nodes from some starting node to any node in the tree along the parent-child connections. The path must contain at least one node and does not need to go through the root.

For example: Given the below binary tree,

   1
  / \
 2   3

Return 6.

The helper function returns the max path including the current node's value.
