Solves the subproblems bottom-up

WebMar 16, 2024 · In the tabulation implementation, we use an array called table to store the results of subproblems, and we use iteration to compute the results. Both implementations achieve the same result, but the approach used is different. Memoization is a top-down approach that uses recursion, while tabulation is a bottom-up approach that uses iteration.
