DP with Trees
When you need to use the solution to the left and right subtree to find the answer to the root, dynamic programming with trees is often relevant. Path sum, tree diameter, and maximum path sum are some examples of DP on trees problems. All of these problems have one thing in common: we get the answers for the left and right subtrees, then apply some math to find answers for the root.
