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.

Input

Input is given from Standard Input in the following format:

N

Solution in Python (3.8.2) (judge verdict: Accepted)

def main():
    N = int(input())
    m = 10 ** 9 + 7
    ans = pow(10, N, m) - 2 * pow(9, N, m) + pow(8, N, m)
    ans = ans % m
    print(ans)
    return
