Sudoku  is a number-placement puzzle. The objective is to fill a  9 × 9  grid with numbers in such a way that each column, each row, and each of the nine  3 × 3  sub-grids that compose the grid  all  contain  all  of the numbers from  1  to  9  one time. Implement an algorithm that will check whether the given  grid  of numbers represents a valid  Sudoku  puzzle according to the layout rules described above. Note that the puzzle represented by  grid  does not have to be solvable. <?php function sudoku2($grid) {    $n=count($grid);    $m=count($grid[0]);    if($n==$m)    {        $status=true;        foreach($grid as $key=>$gridDetail)        {            $gridDetail=str_replace (".","",$gridDetail);            $gridDetail=array_filter($gridDetail);                     foreach($gridDetail as $keydetail=>$gridInfo)           {               $arrayindex=checkdetail($key,$keydetail);                           i
