sub splitStr {my ( $strtmp, $length ) = @_;my $strLength = length $strtmp;my @results;for ( my $i = 0 ; $i < $strLength ; $i += $length ) {#if length reach the bound , just resturn the left ones if ( $strLength < ( $i + $length ) ) {push @results, substr( $strtmp, $i );}else {push @results, substr( $strtmp, $i, $length );}}return \@results;}
