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.
Number K of test cases (K is approximately 1000);
in each of the next K lines there is one integer n (1 <= n <= 20000)
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).
Input: 3 17 11011 17 Output: 11101 11011 11101

If the number is even: result = str(foo(num/2))+'0'. But will this help?
wow feeling good ..... Brilliant question : )
problem can be solve without using bfs. hint: using complete binary tree
test cases are weak add 1998
stl string gives tle
7.42s with C++ ( cin, cout ) :-ss . .......
Brilliant question. Just look at my history of submissions of this question:
A Brilliant question . Guys jst do it urself. All the time will be worth.Dot
I cant solve it... The only way i know is making a list with all numbers with ones and zeros... I only know C :(Last edit: 2015-01-19 00:36:46
