Traceback of First Letter

when trying to align devaroelawrence and trevorlawrence it returns

-d-ev-aroelawrence
r-revo-r--lawrence

however if I change line 272 in NeedlemanWunsch.java from

alignedStrand2 = strand2.charAt(j-k) + alignedStrand2;
to
alignedStrand2 = strand2.charAt(j-k-1) + alignedStrand2;

the alignment produced is

-d-ev-aroelawrence
t-revo-r--lawrence

I did not review the rest of the code for similar errors

Edit: after the previous fix when aligning
dexterlawrence and trevorlawrence (with scoring 5,-2,-1) I had the alignment
extt-e--rlawrence
---trevorlawrence
however, when updating line 282 to
alignedStrand1 = strand1.charAt(i-k-1) + alignedStrand1;
I now get the alignment
dext-e--rlawrence
---trevorlawrence
