WebJul 4, 2024 · As with general dynamic programming, we’re required to think of 3 things. The DP state information you will keep. The solution to the base case. How to go from a smaller solution to a larger solution. A common idea in DP on Trees is to have the sub-problems represent answers for subtrees (+ some state, we’ll see what this means in a bit). http://duoduokou.com/algorithm/50848595680699095719.html
