WebDec 5, 2024 · In Dynamic Programming (DP) we build the solution as we go along. In our case, this means that our initial state will be any first node to visit, and then we expand each state by adding every possible node to make a path of size 2, and so on. Each time we visit a partial solution that’s been visited before, we only keep the best score yet.
