Hi, So I have submitted my response before the lab 1 announcement/questions was changed and managed to get the full marks. Now I am reworking on the lab 1 again. I tried applying the same answers I had whilst changing some of the code so the king completes his tour (ie. start and end at city 0). However now I am facing a problem with test case 4. The tour distance is expected to be 175 but my answer keeps giving me 185. I have reworked it several times but still can't manage to get it to 175. I think my algorithms look logical but I don't know what its lacking of. Is there the test 4 matrix for us to see so I can work out where I went wrong or is there any other suggestions for me? Kind regards.
