WebOptimal Substructure The most important aspect of this problem that encourages us to solve this through dynamic programming is that it can be simplified to smaller subproblems. Let f (N) f (N) represent the minimum number of coins required for a value of N N. Visualize f (N) f (N) as a stack of coins. What is the coin at the top of the stack? WebJan 30, 2024 · DP is an algorithm technique to problems that have an optimal substructure and overlapping subproblems. In contrast, if problems have the non-overlapping subproblems property, you only need to solve it once. In the top-down DP approach (see below) we find a solution based on previously stored results. inbody webshop
