Regarding a test case

    A
    Input:	"a", "c", ["a","b","c"]
    Output:	1
    Expected:	2
    

    Why should the expected output be 2 here?

    L

    In my understand, I think for this problem, the least steps is 2, so if found, it is at least 2, the count should include the begin word and the end word.
