B'Stanley defines the beauty of an array a of length n , which contains non-negative integers, as follows: sum limits_{i = 1}^{n} <= ft lfloor frac{a_{i}}{k} right rfloor, which means that we divide each element by k , round it down, and sum up the resulting values. Stanley told Sam the integer k and asked him to find an array a of n non-negative integers, such that the beauty is equal to b and the sum of elements is equal to s . Help Sam -- find any of the arrays satisfying the conditions above. Each test contains multiple test cases. The first line contains the number of test cases t ( 1 <= t <= 1000 ). Description of the test cases follows. The first line of each test case contains integers n , k , b , s ( 1 <= q n <= q 10^{5} , 1 <= q k <= q 10^{9} , 0 <= q b <= q 10^{9} , 0 <= q s <= q 10^{18} ). It is guaranteed that the sum of n over all test cases does not exceed 10^5 . For each test case print -1 if such array a does not exist. Otherwise print n non-negative integers a_1, a_2, ldots, a_n ( 0 <= q a_{i} <= q 10^{18} ) -- the answer. 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 a = [0, 0, 19] . The sum of elements in it is equal to 19, the beauty of it is equal to <= ft ( <= ft lfloor frac{0}{6} right rfloor + <= ft lfloor frac{0}{6} right rfloor + <= ft lfloor frac{19}{6} right rfloor right ) = (0 + 0 + 3) = 3 . In the fourth testcase of the example a = [0, 3, 3, 3, 29] . The sum of elements in it is equal to 38 , the beauty of it is equal to (0 + 0 + 0 + 0 + 7) = 7 . '...
