[Biojava-l] GCG checkSums

[Matthew Pocock]

Hi Russell,

Is this code in BioJava? I sugest re-writing this to move 
seq.toUpperCase() out of the loop over i as this is potentialy 
expensive. Something like:

 >       int GCG_Checksum(String seq){
 >         int count = 0,
 >             check = 0;
           String seq_uc = seq.toUpperCase();
 >         for(int i = 0; i < seq.length(); i++) {
 >          count++;
 >          //check += count * seq.toUpperCase().charAt(i);
            check += count * seq_uc.charAt(i);
 >             if(count == 57)count = 0;
 >          }
 >           return  check %= 10000;
 >       }
