in reply to asterisk pattern

The following works for me:

$b=this_code_is_from_perlmonks_org; for my $a(some_program_was_written_for_perlmonks_org=~/[st]/g){ print $a,sprintf '%4s','*'x(2+($a cmp $b)), qq(\n); $b=$a }

Update: I didn't get the requirement of outputting different depths, so here is an improved variation on the same theme:

$level=12; my $i=12; my $l=$level-12; $_ = #$; this_program_source_was_written_for_the_site_perlmonks_org. please_do_not_give_this_code_to_your_teacher_without_understanding. We_value_learning_but_the_work_has_to_be_done_by_yourself. kthxbai; $b=a_program_written_by_Corion; for $a(($_.reverse)=~/[sx]/g){ $d=($a cmp $b)||$d; $l+=$d; $b=$a; print sprintf '%'.$i.'s', '*'x$l, qq(\n) unless $l<0 }
