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

填空处的代码可由以下部分组成

①d(i)=0 ②=val(Mid(si, 1) ③IFd(t)<>0Andi-d(t)> c Then c=i-d(t)

④d(i)=1 ⑤t=Asc(Mid(s, i, 1)-Asc("a")+1 ⑥fi-d(t)> c Then c=i-d(t)

代码顺序正确的是（  ）
