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

 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（  ）

执行这部分流程后，变量x的值是（  ）

s=0

For k=1 To 5

s=s * k

Next k

Print s

from random import randint

s=["C++","Java","VB","Pascal","C","Python"]

for i in range(2):

    k=randint(0,2)*2

    s=s[:k]+s[k+1:]

print(s)

执行该程序段后，变量s的值不可能是（    ）
