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

can someone help...how to solve this problem.. even if i use BFS and store numbers as string, then how to get number from large strings greater than 64 bits and check if it is fully divisible by given integer, or there is some other way to this. Last edit: 2015-07-26 12:07:56 |
