请回答以下问题。

Private Sub Command2_Click()

Dim i As Integer, j As Integer, tmp As Integer

Dim s1 As String, t As Integer, s2 As String

t=1

For i=1 To n-2

    For j= To n Step 2     ‘改错

        If a(i)*t>a(j)*t Then

            tmp =a(i): a(i)= a(j): a(j)=tmp

        End if

    Next j

                   ‘填空①

Next i

For i =1 To n

    If     Then       ‘填空②

        s1 =s1 Str(a(i))

    Else

        s2=s2+Str(a(i))

    End If

Text2. Text=“奇数位：”+s1

Text3. Text=“偶数位：”+s2

End Sub

回答以下问题：

For i=1 To 6

    x=Int(Rnd*10)+1

    If i Mod 2 = 1 Then

        a(i)=2*x+1

    Elself x Mod 2 = 0 Then

        a(i)=x/2

    Else

        a(i)=x-1

    End If

Next i

执行该程序段后，a(1)～a(6)各元素可能的值是（  ）

Dim a(1 To 6) As Integer

Randomize

a=n Mod k

n=n\k,k=k+1,s=s+a

a(1) = Int(11 * Rnd) + 2

For i = 2 To 6

a(i) = Int(11 * Rnd) + 2

If i Mod 2 = 1 And Not prime(a(i)) Then i = i - 1

ElseIf Not prime(a(i)) Then a(i) = a(i) + a(i - 1)

End If

Next i

'自定义函数 prime()用于判断参数是否为质数，prime(n) = True 则说明 n 为质数，否则为合数，定义函数代码略执行该程序后，a(1)～a(6)的值不．可．能．为（  ）

import math

h = 500

g = 9.8

t = math.sqrt（2*h/g）

hx = g*（t-1）*（-1）/2

hh = h-hx

print（“小球最后1秒下落的位移是：”，hh，“m”）
