For i = 1 To 5

 b(a(i)) = b(a(i)) + 1

Next i

pa = 0

For j = 1 To 10

 For k = 1 To b(j)

pa= pa + 1 : a(pa) = j

 Next k

Next j

a(1)到a(5)的初值依次是7、5、9、4、3，程序段运行后，数组a值依次是（  ）

Dim a(1 To 100) As Integer

Dim b(1 To 100) As Integer

Dim c As Integer

a(1) = 0: a(2) = 2: b(1) = 1: b(2) = 2: c = 0

For i = 2 To 6

  a(i + 1) = 2 * a(i) - a(i - 1)

  b(i + 1) = b(i) ^ 2 / b(i - 1)

c = c + a(i + 1) + b(i + 1)

Next i

Label1.Caption = Str(c)

该程序运行后，Label1中显示的内容是（  ）

Private Sub Command1_Click()

    Dim a(0 To 9) As Integer

    Dim t as Long

    t = Val(Text1.Text)

    Do While t <> 0

        a(t Mod 10) = 1

        t = t \ 10

    Loop

    For i = 0 To 9

        x = x + a(i)

    Next i

End Sub

若在文本框Text1中输入10242048，则程序执行后，变量x的值为（  ）

from random import random

a=[1]*5

i=1

while i<=4:

    a[i]=int(random()*10)+1

    if a[i]==a[i-1]//2 or a[i]==a[i-1]*2:

        i+=1

执行该程序段后，数组a的值可能是（   ）
