For i = 1 To 2

For j = 1 To 6 - 2 * i

If  a(j) < a(j + 2) Then

t = a(j): a(j) = a(j + 2): a(j + 2) = t

End If

Next j Next i

数组元素a(1)~a(6)的初始值依次为“15，13，44，38，26，7”，执行该程序段后，数组a元素的值分别为（   ）

a(i)= Int(Rnd * 20) + 1 Next i

For i= 2 To 5

If i Mod 2 = 1 And a(i-1) < a(i)Then  t=a(i):a(i)=a(i-1):a(i-1)=t

Else

a(i)=a(i)-1 End If

Next i

执行该程序段后，a（1）~ a（5）各元素不可能的值是（  ）

a(1) = 1

 For i = 2 To 6

 Randomize

 a(i) = a(i - 1) + Int(Rnd * 5 + 1)

 If a(i) Mod 2 = 1 Then

   a(i) = a(i) \ 2 + 1

 Else

   a(i) = a(i) / 2

 End If

 Next i

执行程序后，a数组各元素可能是（  ）

For i = 1 To 9 Step 2

  b(a(i) Mod 10) = b(a(i) Mod 10) + 1

Next i

s = 0

For i = 0 To 9 Step 3

  s =s + b(i)

Next i

数组b各元素初始值为0， 数组元素a(1)到a(9)的值依次为“29,74,12,38,16,45,21,57,33”,则执行该程序段后，s的值为（  ）

s = "123456789"

g = ""

For i = 1 To 3

  n = Len(s)

  x = Int(Rnd * n) + 1

  g = g + Mid(s, x, 1)

  s = Mid(s, 1, x - 1) + Mid(s, x + 1, n - x)

Next i

在程序执行时，若变量x的值依次为3，3，6，则最终变量g的值为（  ）

Do While i <= j

  m =(i + j) \ 2

  End If

Loop

Text1.Text = s

数组元素a(1)到a(8)的值依次为“4,22,27,32,35,44,56,59”，该程序段执行后，文本框Text1中显示的内容不可能是（  ）

For i = 1 To 5

 k = i

 For j = i + 1 To 6

  If a(k) > a(j) Then k = j

 Next j

 t = a(k): a(k) = a(i): a(i) = t

 s1 = ""

 n = Len(s)

 For i = 1 To n \ 2

   If Mid(s, i, 1) > Mid(s, n - i + 1, 1) Then

     s1 = s1 + Mid(s, i, 1)

   Else

     s1 = Mid(s, n - i + 1, 1) + s1

   End If

 Next i

 Text1.Text = s1

执行该程序段后，在文本框Text1中显示的是（  ）

s = "2019appreciate": sum = 0

For i = 1 To Len(s)

  ch = Mid(s, i, 1)

  If ch >= "a" And ch <= "z" Then

    m = Asc(ch) - Asc("a") + 1

    a(m) = a(m) + 1

  End If

 Next i

 For i = 1 To 10

  If a(i) > 0 Then sum = sum + 1

 Next i

数组a各元素的初始值都为0，执行该程序段后，变量sum的值为（  ）
