There are two popular ways to solve DP problems: the tabular method and memoization. In the tabular method, we build a matrix that stores the intermediate values one by one in the lookup table. On the other hand, in the memoization method, we store the same values in an unstructured way. Here, unstructured way refers to the fact that the lookup table may be filled all at once.
