若采用选择排序算法对其进行从大到小排序，则第二趟的排序结果是（   ）

a(1)=6:a(2)=8:a(3)=7:a(4)=3:a(5)=1:a(6)=2:a(7)=5:a(8)=4

i = 1: j = 8

key = a(1)

Do While i < j

 Do While i < j And a(j) >= key

  j = j - 1

 Loop

 a(i) = a(j)

 Do While i < j And a(i) <= key

  i = i + 1

 Loop

 a(j) = a(i)

Loop

a(i) = key

For i = 1 To 8

 Label1.Caption=Label1.Caption++Str(a(i))

Next i

执行该程序段，标签Label1上显示的内容是(  )

Private Sub Command1_ Click ( )

  Dim a(1 To 5) As Integer, i As Integer, 3 As Integer, c As Integer

  a(1) = 22: a(2) = 44: a(3) = 11: a(4) =33: a(5) = 55: c = 0

  For i = 1 To 4

m = i

For j = i + 1 To 5

  If a(i) > a(m) Then m = j

    Next j

    If m <> i Then

      t=a(1) : a(i)=a(m) : a(m)=t

      c=c+1

    End If

  Next i

  Label1.Caption= Str (c)

End sub

该程序运行后，标签Label1中显示的内容是（  ）
