f = 0 Else
If n = 2 Or n = 3 Then f = 1 Else
f = f(n - 3) + 2 * f(n - 2) + f(n - 1) End If End If End Function 52、 答案: 6532 s = 0
For i = 12709 To 45368 a = Int(i / 10000)
b = Int((i - a * 10000) / 1000) c = Int((i - a * 10000 - b * 1000) / 100) d = Int((i - a * 10000 - b * 1000 - c * 100) / 10) e = i - a * 10000 - b * 1000 - c * 100 - d * 10 If (a + b + c + d + e) Mod 5 = 0 Then s = s + 1 Next Print s
