B'oolimry has an array a of length n which he really likes. Today, you have changed his array to b , a permutation of a , to make him sad. Because oolimry is only a duck, he can only perform the following operation to restore his array: The sadness of the array b is the minimum number of operations needed to transform b into a . Given the array a , find any array b which is a permutation of a that has the maximum sadness over all permutations of the array a . Each test contains multiple test cases. The first line contains a single integer t ( 1 <= q t <= q 10^4 ) -- the number of test cases. The description of the test cases follows. The first line of each test case contains a single integer n ( 1 <= q n <= q 2 cdot 10^5 ) -- the length of the array. The second line of each test case contains n integers a_1, a_2, ldots, a_n ( 1 <= q a_i <= q n ) -- elements of the array a . It is guaranteed that the sum of n over all test cases does not exceed 2 cdot 10^5 . For each test case, print n integers b_1, b_2, ldots, b_n -- describing the array b . If there are multiple answers, you may print any. In the first test case, the array [1,2] has sadness 1 . We can transform [1,2] into [2,1] using one operation with (i,j)=(1,2) . In the second test case, the array [3,3,2,1] has sadness 2 . We can transform [3,3,2,1] into [1,2,3,3] with two operations with (i,j)=(1,4) and (i,j)=(2,3) respectively. '...
