（加试题）编写一个成绩查询程序，输入要查找的分数，输出该分数的名次及同分人数，其算法是：用数组a存放不同的分值，数组m存储相同分数的人数，数组mc存储不同分数的名次。例如，数据库中有一组成绩（已按降序排列）：98，95，95，92，90，90，87，按该算法，各数组值如下表所示：

i	1	2	3	4	5
a	98	95	92	90	87
m	1	2	1	2	1
mc	1	2	4	5	7

 
程序界面如下图所示，在文本框Text1中输入查询成绩，点击“查找”按钮，若找到，则输出该分数的名次和同分数的人数，若找不到，则输出“查无此分”。

程序代码如下，请在划线处填入合适的代码。
Dim n As Integer
Dim a(l To 1000) As Integer ’存放不同的分数值
Dim m(0 To 1000) As Integer ’存放相同分数的人数
Dim mc (0 To 1000) As Integer ’存放此分数的名次
Private Sub Form_Load()
Dim conn As New ADODB. Connection
Dim rs As New ADODB. Recordset
Dim tmp As Integer
Dim s As Integer
tmp = -1: n = 0
conn. Connectionstring = 〃provider=Microsoft. AC

A．OLEDB. 12. 0; data source=〃 & App. Path & 〃\mydb. accdb〃

conn. Open
Set rs. ActiveConnection = conn
rs.Open "Select * from score"
mc(0) = 1: m(0) = 0

Do While Not rs. EOF

s = rs. Fields (〃成绩〃)
If s = tmp Then ’当前读入分数与上一个分数相同
m(n) = __________
Else
n = n + 1
a(n) = s
m(n) = 1
mc(n) = ___________ 
End If
_____________
rs. MoveNext

Loop

End Sub
Private Sub Command1_Click0
Dim key As Integer, i As Integer, j As Integer, mid As Integer
key = Val (Text1.Text)
i = 1: j = n
mid = (i + j) \ 2
Do While i <= j And ____________ 

mid = (i + j) \ 2

If a(mid) < key Then

j = mid – 1

Else

i = mid + 1

End If

Loop
If a(mid) = key Then

Label2. Caption = 〃名次: 〃+ Str(mc (mid)) + 〃同分人数: 〃+ Str(m(mid))

Else

Label2. Caption = 〃查无此分〃

End If
End Sub
