ONEZERO - Ones and zeros

Certain positive integers have their decimal representation consisting only of ones and zeros, and having at least one digit one, e.g. 101. If a positive integer does not have such a property, one can try to multiply it by some positive integer to find out whether the product has this property.

Input

Number K of test cases (K is approximately 1000);
In each of the next K lines there is one integer n (1 ≤ n ≤ 20000)

Output

For each test case, your program should compute the smallest multiple of the number n consisting only of digits 1 and 0 (beginning with 1).

Example

Input:
3
17
11011
17

Output:
11101
11011
11101

@Anubhav Bindlish
even if you ignore data not coprime to 10, it remains a few cases (about one hundred) not fitting in a 64 bit integer

Will the answer fit in 64 bit integer?

modular maths FTW :D (y) !!!!
hint: only one character array required

ans for 19998??

i think 9999 is not included in the test cases... anyway nice problem :)

Very good question.. BFS.. Must solve.. Solved in 9 hrs, but was worth...

Have an optimized I/O and some tricks up sleeve to get AC ... btw dont need strings for and it keep it simple ... excellent problem , spent 6 hours on it and enjoyed .. XD.
