Dear GP,

Are duplicates allowed in the number list and are numbers constrained to be integer?
Yes they can be duplicates. But the array is always sorted in ascending order. So for example given @nlist = (0,0,1,2,3,3,4,5,6,8,8,10);. We would like to have such cluster: 
# I have manually align this based on the centroid
                     
                    Centroid
                      |  
my $VAR1 = {         #V
 
          'A' =>   [0,0,1],
          'B' => [0,0,1,2],
          'C' =>   [1,2,3,3],
          'D' =>   [2,3,3,4],
          'E' => [3,3,4,5],
          'F' =>   [4,5,6], 
          'G' =>   [5,6]   
          'H' =>     [8,8],      
          'I' =>     [10],    
        };

I'm sorry for not being clear in the first place.
What happens to hash keys if there are more than 26 keys?
As stated in my snippet. I have made sure that the cluster won't need more than 26 keys.

Regards,
Edward
