It may be tempting to solve this problem with greedy strategy but, as the example shows, it gives the wrong answer.

To reach (i, j), there are two options (i-1, j) or (i, j-1) (for legal values of i and j). Let’s just iterate through both of them and take the maximum.

Just don’t forget to cache the values, or it will become an exponential time algorithm!
