- The main principle behind dynamic programming is the concept of optimal substructure, where the solution to a problem can be from solutions to subproblems.
- Dynamic programming can be used to solve a wide range of problems including optimization, recursive, and combinatorial problems.
- Dynamic programming uses memoization to store solutions to subproblems, while recursion does not. This is the main difference between the two.
- The knapsack problem can be solved using dynamic programming by using memoization to store the solutions to subproblems.
- The time complexity of dynamic programming algorithms is typically O(n^2) or O(n^3) for problems with overlapping subproblems.
- The primary advantage of using dynamic programming over other approaches is that it guarantees an optimal solution for the problem.
