CF1715B.Beautiful Array
Beautiful Array
Stanley defines the beauty of an array of length , which contains non-negative integers, as follows: $$ um\limits_{i = 1}^{n} \left \lfloor \frac{a_{i}}{k} \right \rfloor,$$which means that we divide each element by, round it down, and sum up the resulting values.
Stanley told Sam the integerand asked him to find an arrayofnon-negative integers, such that the beauty is equal toand the sum of elements is equal to. Help Sam — find any of the arrays satisfying the conditions above.
Input
Each test contains multiple test cases. The first line contains the number of test cases (). Description of the test cases follows.
The first line of each test case contains integers , , , (, , , ).
It is guaranteed that the sum of over all test cases does not exceed .
Output
For each test case print if such array does not exist. Otherwise print non-negative integers () — the answer.
Note
In the first, the second, the fifth and the sixth test cases of the example it is possible to show that such array does not exist.
In the third testcase of the example . The sum of elements in it is equal to 19, the beauty of it is equal to $\left ( \left \lfloor \frac{0}{6} \right \rfloor + \left \lfloor \frac{0}{6} \right \rfloor + \left \lfloor \frac{19}{6} \right \rfloor \right ) = (0 + 0 + 3) = 3$.
In the fourth testcase of the example . The sum of elements in it is equal to , the beauty of it is equal to .
