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 C (GCC 9.2.1) (judge verdict: Wrong Answer)

#include<stdio.h>
int main(void){
    int N;
    scanf("%d",&N);
    if(N <= 2){
        printf("%d\n",(N-2+1)%(10^9 + 7));
    }
    else
    {
        printf("%d\n",(6*9^(N-1))%(10^9 + 7));
    }
    return 0;
}
