efefefef

it's not a simiple conversion of rows to columns which i'm able to do but taking every pair of elements of a row and turning them into columns I've tried the following without success 
foreach $line (@array)
{
    chomp $line;
    @xox=split(//,$line);
    $cnt=0;
    for($i=0; $i<=scalar(@xox); $i+=2)
    {
        push $arr[$cnt], $xox[$i]."".$xox[1+$i];
        $cnt++;
    }
}
