执行该算法，当x的值为5时，（   ）

Dim i As Integer, Sum As Integer

Dim a(1 To 11) As Integer

Sum = 6

a(11) = 49

For i = 10 To 1 Step -1

  a(i) = a(i + 1) - 1

  If a(i) Mod 3 = 0 Then Sum = Sum + a(i)

Next i

Text1.Text = Str(Sum)

该程序段运行后，文本框text1中显示的内容是（   ）

n = Len(Text1.Text)

For i = 1 To n

 a(i) = Mid(Text1.Text, i, 1)

Next i

Do While n > 1

 If Asc(a(n)) >= Asc(a(n - 1)) Then

    m = 1

 Else

    m = 2

 End If

 b(m) = b(m) + 1

 n = n-1

Loop

数组b各元素的初始值都为0，文本框Text1的内容为“2018Python”。执行程序后，变量b(1)的值为（  ）

 Dim a(3, 3) As Integer

 For m = 1 To 3

 For n = 1 To 3

   a(m, n)=(m-1)*3+n

 Next n

 Next m

   For m = 2 To 3

For n = 1 To 2

   Print a(n, m);

Next n

Next m

运行后输出结果是（  ）
