"WebTop-down is a recursive problem-solving approach, while bottom-up is an iterative approach. In other words, the top-down approach assumes the subproblems will be solved using the smaller sub-problem only once using the recursion. In reverse, bottom-up composes the subproblems’ solution iteratively using the smaller sub-problems. " - Recursion bottom up
