Please helping write the code for the scale down. the size after scaling down can't less than 2x2

private DynamicArray<DynamicArray<Tile>> block;
public Block(int y, int x, int size)...
/** ...

{
}
if (y >= 0 && y < block.size() && x >= 0 && x < block.get(y).size()) {

scale down (shrink in half, but can't become smaller than 2x2).
public Block scaleDown() // scales down the block (half size) -- O(block_size)
