CF1779B.MKnez's ConstructiveForces Task
MKnez's ConstructiveForces Task
MKnez wants to construct an array satisfying the following conditions:
- Each element is an integer number different from ;
- For each pair of adjacent elements their sum is equal to the sum of the whole array.
More formally, must hold for each . Moreover, it must hold that for each .
Help MKnez to construct an array with these properties or determine that it does not exist.
Input
Each test contains multiple test cases. The first line contains the number of test cases (). The description of the test cases follows.
The only line of each test case contains a single integer () — the length of the array.
Output
For each test case, print "YES" if an array of length satisfying the conditions exists. Otherwise, print "NO". If the answer is "YES", on the next line print a sequence satisfying the conditions. Each element should be a non-zero integer in the range , i. e. and should hold for each .
It can be proved that if a solution exists then there also exists one which satisfies the additional constraints on the range.
If there are several correct answers, print any of them.
Note
In the first test case, is a valid answer since (the sum of the two adjacent elements ) is equal to (the sum of all elements). Other solutions include
For the second test case, let us show why some arrays do not satisfy the constraints:
- — and differ;
- — and differ;
- — The array cannot contain a .
This is not a proof, but it can be shown that the answer is "NO".
