Hey, hey, nothing upstairs is right. This question is a bit difficult. . . ~~! ! ! ! ~~! !

In fact, this question is to look at individual figures separately.

1=0

2=0

3=0

4=0

5=0

6= 1

7=0

8=2

9= 1 If you look at "6", "8" and "9" separately, they all contain small "0" ~! ~!

……

So, get the above rule. .

12345=0 23456= 16 34567= 1 645678=36.8 56789=4.6.8.9。 .
