Hello Monks, Im trying to convert a sequence of 1's and 0's into s new sequence which is the length of 1's, so;

@a = (0,0,1,1,1,0)

needs to be

@b = (0,0,3,0)

I then need to go one step further, changing the new sequence into letters, where each letter corresponds to a different number (assuming my maximum number of 1's in a row is 15) My input is a file of 1's and 0's. Ive tried this code, but it wont work! 


my @result   = split '', 'abcdefghijklmno';
my @arg1   = (0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15);
my %rules;


# Build the rules hash
$rules{$arg1[$_]} = $result[$_] for 0 .. $#result;

my @newseq = ();
my $run = 0;
my @bin = ();


while ( <INFILE> ) {
   @bin= split(/ /, $_);
   for (my $i=0;$i<$#bin;$i++) {
      if ($bin[$i]==0){
         $run=0;
         push @newseq,$run;
      }
      if ($bin[$i]==1 && $bin[$i+1]==0){
         $run++;
         push @newseq, $run;
      }
      else {
         $run++;
      }
   }
}


 for (1 .. $#newseq) {
    if ( $_ % 80 != 0){ print "$rules{$newseq[$_-1]}"}
       else{  print  "$rules{$newseq[$_-1]}\n"; }
 }

The @newseq array is always empty, I must be doing something wrong and initializing in the wrong place, but I cant see where. Any ideas on a better way to do this would also be appreciated. Thanks.
