SPOJ Problem Set (classical)

370. Ones and zeros

Problem code: ONEZERO

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

@strings: use strings , I got accepted with strings.

@thefourtheye you didn't get my point. ! can precompute the values no doubt about that... but for those whose values lie outside long long?? 396,594,999,9999 etc are just xamples of some of those values... please tell what to do... strings?? precomputation??

@C****** 396 => 11111111111111111100

there are 235 test cases like 396,999,9999 etc which have reqd ans outside the limits of long long, so how to deal wid them??
strings?? precomputation??
please reply !!
