CF1867A.green_gold_dog, array and permutation
green_gold_dog, array and permutation
green_gold_dog has an array of length , and he wants to find a permutation of length such that the number of distinct numbers in the element-wise difference between array and permutation is maximized.
A permutation of length is an array consisting of distinct integers from to in any order. For example, is a permutation, but is not a permutation (as appears twice in the array) and is also not a permutation (as , but appears in the array).
The element-wise difference between two arrays and of length is an array of length , where = ().
Input
Each test contains multiple test cases. The first line contains the number of test cases (). The description of the test cases follows.
The first line of each test case contains a single integer ().
The second 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, output numbers - a suitable permutation . If there are multiple solutions, print any of them.
Note
In the first set of input data, the element-wise difference of the arrays is [99999]. Here, there is one distinct number, and it is obvious that in an array of length one, there cannot be more than one different element.
In the second set of input data, the element-wise difference of the arrays is [-1, 0]. Here, there are two distinct numbers, and it is obvious that in an array of length two, there cannot be more than two different elements.
In the third set of input data, the element-wise difference of the arrays is [9, 0, 1]. Here, there are three distinct numbers, and it is obvious that in an array of length three, there cannot be more than three different elements.
