Problem Statement

How many integer sequences A_1,A_2,\ldots,A_N of length N satisfy all of the following conditions?

0 \leq A_i \leq 9

There exists some i such that A_i=0 holds.

There exists some i such that A_i=9 holds.

The answer can be very large, so output it modulo 10^9 + 7.

Constraints

1 \leq N \leq 10^6

N is an integer.

Solution in Julia (1.4.0) (judge verdict: Wrong Answer)

function main()
  n=parse(Int64,readline())
  a,b,c=1,2,1
  d=Int(1e9+7)
  for i=1:n
    a=10*a%d
    b=9*b%d
    c=8*c%d
  end
  println((a-b+c)%d)
end
main()
