We can select the cells with values 1, 3, and 4 that are colored above.
\nYou are given a 2D matrix grid consisting of positive integers.
You have to select one or more cells from the matrix such that the following conditions are satisfied:
\n\nYour score will be the sum of the values of the selected cells.
\n\nReturn the maximum score you can achieve.
