Converting a bottom up solution to top down is pretty straightforward, you … WebFeb 28, 2024 · 3. Approaches to Implement Dynamic Programming. We can solve dynamic programming problems with the bottom-up or top-down approach. Regardless of which, we need to define and come out with the base case of the problem. Generally, the top-down approach starts by looking at the big picture.
