I completed the DNA problem on pset6. There is a series of tests you need to enter into the command line before you submit, and I did all of them and passed every single one (as shown below).
However, when I used submit50 and submitted my code, I only got 42%.
Even when I go into the link it gave me and look further into the check50 to see what I got wrong, I see that it's failing tests that work even when I copy the command straight from that page back into my command prompt.
^ Fails all the other ones not shown in the picture
