$value = "system";
@SortedArray = split('',$value);
$strlength = @SortedArray;
print "Current sort @SortedArray

$swapped = 0;
for($i=0; $i < $strlength; $i++){
for (my $j = 0; $j < $strlength-1-$i; $j++) {
if($SortedArray[$j] gt $SortedArray[$j+1]){
$tmp = $SortedArray[$j];
$SortedArray[$j] = $SortedArray[$j+1];
$SortedArray[$j+1] = $tmp;
