Currently, the riffle shuffle is only done pseudo-randomly, though the contest announcement said otherwise (i.e. it is not guaranteed that it's random). This is because the test data doesn't contain any information about how the shuffle should be done. The problem might be rejudged if we manage to find the correct shuffling method for each test.
