题目

某算法的 VB 程序段如下： Const n = 5 Dim d(1 To n) As Integer For i = 1 To n     d(i) = Int(Rnd * 10 + 1) Next i i = 1 Do While i <= n - 1     For j = n To i + 1 Step -1         If d(j) Mod 2 = d(j - 1) Mod 2 Then If d(j) < d(j - 1) Then             t = d(j): d(j) = d(j - 1): d(j - 1) = t         End If         ElseIf d(j) Mod 2 = 1 And d(j - 1) Mod 2 = 0 Then             t = d(j): d(j) = d(j - 1): d(j - 1) = t         End If     Next j     i = i + 1 Loop 执行该程序段后，数组元素 d(1)到d(n)的值不可能为（     ） A . 7 11 15 16 19 B . 1 9 11 15 19 C . 2 8 10 18 20 D . 11 2 10 12 16 答案：A
