Hi monks,

I having an array which consist of the level values of the section in a book.

I want to generate the another array which will be based on the levels in the previous array.

Input:

@t=(0,1,1,2,3,2,1,2)

Here 0 means section 1, 1 means section 2, etc.

Output:

@out=(1, 1.a, 1.b, 1.b.1, 1.b.1.a, 1.b.2, 1.c, 2, 2.a, 2.a.1); In the output array i want even 

@t=(0,1,1,2,3,2,1,0,1,2);
$"='.';
my %h=(
'1'=>    'a', 
'2'=>    'b', 
'3'=>    'c', 
'4'=>    'd', 
'5'=>    'e', 
'6'=>    'f', 
'7'=>    'g', 
'8'=>    'h', 
'9'=>    'i', 
'10'=>    'j',
'11'=>    'k',
'12'=>    'l',
'13'=>    'm',
'14'=>    'n',
'15'=>    'o',
'16'=>    'p',
'17'=>    'q',
'18'=>    'r');

my @s;
foreach my $t (@t)
{    
my $s;
my @id=map{$s++;($s%2 == 0)?$h{$_}:$_}map{$#s=$_;++$s[$_];@s}$t;
push(@out, "@id");
}

print @out;

Even though Im getting the desired output. I dont want to use an hash which consist of alpahbetic values for corresponding numerals. Does it can be done with the help of chr function or any other way.

Many thanks in advance.
