found some l1 test bug

[WIZARD-CXY]

Just finish the l1 test. I think the reverse test code should be

if slice[0] != myType(2) || slice[1] != myType(1) || slice[2] != myType(0) || len(slice) != 3 {
        t.Fail()
}

otherwise if we don't reverse the slice and just use the old slice which is [0,1,2], it passes the test

maybe just a subtle bug,never mind
