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 PyPy3 (7.3.0) (judge verdict: Accepted)

N = int(input())

n10 = 1
n8 = 1
n9 = 1
for _ in [0]*N:
    n10 = n10*10 %(10**9+7)
    n8 = n8*8 %(10**9+7)
    n9 = n9*9 %(10**9+7)

ans = (n10+n8-2*n9)%(10**9+7)
print(ans)
