WebDynamic programming is a technique that solves the optimization problem. Optimization problem uses either minimum or maximum result. In contrast to dynamic programming, backtracking uses the brute force approach without considering the optimization problem. If we have multiple solutions then it considers all those solutions. WebDynamic program uses bottom-up approach, saves the previous solution and refer it, this will allow us to make optimal solution among all available solutions, whereas greedy approach uses the top-down approach, so it takes an optimal solution from the locally available solution, will not take the previous level solutions which leads to the less …
