To find the deepest node in a binary tree, we can use recursion. We can keep track of the maximum depth as we traverse the tree, and return the deepest node's value when we reach the end of the tree.

A.I. Evaluation of the Solution

This is a good solution that correctly finds the deepest node in a binary tree. The approach of using a depth first search is a good one, as it only needs to traverse the tree once. The code is well-written and easy to follow.
