Problem A
I Hate The Number Nine
How many positive $d$ digit numbers exist that do not contain a nine?
Input
The first line of the input consists of a single integer,
$T$, the number of test
cases.
Each of the following $T$
cases consists of a single integer $d$, the number of digits.
-
$1 \leq T \leq 20$
-
$1 \leq d \leq 10^{18}$
Output
For each test case, output the number of positive numbers with $d$ digits that do not contain a nine. Since this number can be very large, output it modulo $1\, 000\, 000\, 007$.
