CodeHS 8.1.5 requires updating the final elements of three 2D array rows, replacing placeholder zeros with specific values calculated using a helper method, including the first row's length, the total element count, and sum of specific elements. Implementation involves iterating through rows to sum lengths and using the arr[row][col] = value formula to update indices, taking care to avoid out-of-bounds errors.
