WebJul 4, 2024 · Divide and conquer: Does more work on the sub-problems and hence has more time consumption. In divide and conquer the sub-problems are independent of each other. Dynamic programming: Solves the sub-problems only once and then stores it in the table. In dynamic programming the sub-problem are not independent. Share. Web1. In Memoization, you store the expensive function calls in a cache and call back from there if exist when needed again. This is a top-down approach, and it has extensive recursive calls. In Dynamic Programming (Dynamic Tables), you break the complex problem into smaller problems and solve each of the problems once. ph of wax
