分,共12分.） 一個自然數(shù)倒過來讀仍是這個數(shù),就叫回文數(shù),有些回文數(shù)還是素數(shù),就叫回文式素數(shù),如9323
Function hw(m As Long) As Boolean
Dim a As Integer,b As Integer,c As Integer,d As Integer
a = Left(m,1):b = Mid(m,2,1)
c = _____________________
d = _____________________
hw = IIf(a = d And b = c,True,False)
End Function
Function ss(m As Long) As Boolean
Dim k As Long,i As Long,f As Boolean
f=True
k = Sqr(m)
For i = 2 To k
If _____________________ Then
f = False
Exit For
End If
Next i

Private Sub Command1_Click()
Dim m As Long,n As Integer
For m = 10000 To 99999
If _____________________________ Then
Print Tab((n Mod 10) * 8 + 1); m;
n = n + 1
End If
Next m
End Sub
Mid(m,4,1) Right(m,1) 注意：只要能取出第四、五位即可得分
m mod i=0(只要能判斷整除即可)
ss=f ss(m) hw(m)(只寫ss及hw不得分,如果寫了True但寫錯了扣1分)
