Incorrect test cases and problem statement clarity

    A

    Consider the following test case:

    "AGCAAAAA"
    "GACAAAAA"
    ["AGTAAAAA", "GGTAAAAA", "GATAAAAA", "GACAAAAA"]

    The mutation is possible, but OJ returned -1.
    Also the statement never says that you would have to have make the mutations through valid genes, which is the intent I guess. Also, I am not sure why the start mutation is not part of the bank, although it would not make much difference.

    @amandeepgautam5 Sorry about the bug in my code, I will fix it soon.
    I mean, sometimes you need to mutate multiple times to get the "end" gene string, which means that each mutation needs to be valid to make the whole mutations valid. But I will add this point to the desctiption.
    Also, we assume that the starting point is already valid, so I did not add it to the bank.
    Thank you for your suggestions!
