## Hackerrank - Special Multiple Solution

You are given an integer *N*. Can you find the least positive integer *X* made up of only 9's and 0's, such that, X is a multiple of *N*?

**Update**

*X* is made up of one or more occurences of 9 and zero or more occurences of 0.

**Input Format**

The first line contains an integer T which denotes the number of test cases. T lines follow.

Each line contains the integer *N* for which the solution has to be found.

**Output Format**

Print the answer *X* to STDOUT corresponding to each test case. The output should not contain any leading zeroes.

**Constraints**

1 <= T <= 10^{4}

1 <= N <= 500

**Sample Input**

```
3
5
7
1
```

**Sample Output**

```
90
9009
9
```

**Explanation**

90 is the smallest number made up of 9's and 0's divisible by 5. Similarly, you can derive for other cases.

### Solution in Python

```
from itertools import product
def special(n):
i = 0
while True:
for j in product(*[[0,9]]*i) or [9]:
s = "9"+"".join(map(str,j))
if not int(s)%n:
return s
i+=1
for _ in range(int(input())):
n = int(input())
print(special(n))
```
