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 does not need to go through the root. For example: Given the below binary tree, ...

This is only true if uu is between the leaf in question and every other node in aa, but there may not be any such uu in aa, for example if the leaf in question is in a subtree branching off of a path between two nodes in aa, in a situation that looks something like this: a_...
