题目描述
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.
