一本书265页，在这本书的页码中共用了多少个数字？在这些数字中5和0共出现多少次？

Answer 1

数字总个数=1482
5的出现次数=134
0的出现次数=103
'以上结果由下面VBA程序计算得到
Sub Macro1()
n = 0: m = 0: s = 0
For i = 1 To 265 * 2
x = Len(i)
n = n + x
For j = 1 To 3
w = Mid(i, j, 1)
If w = 5 Then
m = m + 1
End If
If w = 0 Then
s = s + 1
End If
Next j
Cells(1, 3) = s
Cells(1, 2) = m
Cells(1, 1) = n
Next i
End Sub

Answer 2

从100页到265页共166页数字=166*3=498从10页到90页共81页数字=81*3=243从1至9页共9页共计750

Answer 3

9+90*2+166*3=687
