Question 103
The government of Bosnia and Herzegovina has decided to introduce a new system of licence plates. Each licence plate must contain 8 digits, each of which can be $0,1,2,3,4,5,6,7,8$ or $9$. Moreover, two distinct licence plates must always have at least two different digits. For example, if it puts the plate $00000000$ into circulation, the government will not be able to put the plate $00010000$ into circulation.
