有如下VB程序段：
Dim a(1 To 10) As Integer
s = "7218634594": n = Len(s)
t = 0
For i = 1 To n - 1
a(i) = Val(Mid(s, i, 2))
Next i
For i = 1 To n - 2 Step 2
k = i
For j = i + 2 To n - 1 Step 2
If a(j) < a(k) Then k = j
Next j
If k <> i Then
temp = a(i): a(i) = a(k): a(k) = temp: t = t + 1
End If
Next i
Text1.Text = Str(t)
该程序段运行后，文本框Text1中显示的内容是
