.某程序代码如下：（ ） Dim count As Integer
Dim a(1 To 13) As String
s = "where are you"：count= 0
For i = 1 To Len(s)
a(i) = Mid(s, i, 1)
Next i
For i = 1 To Len(s) - 1
k = i
For j = i + 1 To Len(s)
If a(k) < a(j) Then k = j
Next j
If i <> k Then
t = a(i): a(i) = a(k): a(k) = t
End If
Next i
For i = 1 To Len(s) - 1
If a(i) = a(i + 1) Then count = count + 1
Next i
程序运行结束后,变量 count 的值是（ ）
