"WebThe first logical optimization would be to do one-dimensional prefix sums of each row. Then, we'd have the following row-prefix sum matrix. The desired subarray sum of each row in our desired region is simply the green cell minus the red cell in that respective row. We do this for each row to get (28-1) + (14-4) = 37 (28− 1)+(14 −4) = 37. " - Sum of each subarray
