Solution

When a top-down approach of dynamic programming is applied to a problem, it usually decreases the time complexity and increases the space complexity. This is because the top-down approach uses memoization to store the results of subproblems in a table. While this reduces the time complexity by avoiding redundant calculations, it increases the space complexity as more memory is required to store the results.
