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? |

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. |
