In the 4 × 4 array shown below, each cell of the first three rows has either a cross (X) or a number.

The number in a cell represents the count of the immediate neighboring cells (left, right, top, bottom, diagonals) NOT having a cross (X). Given that the last row has no crosses (X), the sum of the four numbers to be filled in the last row is

From looking at the third row, it should be clear that the last row has four numbers. Therefore, these four numbers have to be \(2, 4, 3, 2\). The sum is \(11\).
