CF2107A.LRC and VIP
LRC and VIP
You have an array of size — .
You need to divide the elements into sequences and , satisfying the following conditions:
- Each element belongs to exactly one sequence.
- Both sequences and contain at least one element.
- $(B_1, B_2, \ldots, B_{|B|}) \ne \gcd(C_1, C_2, \ldots, C_{|C|})$
denotes the greatest common divisor (GCD) of integers and .
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 an integer ().
The second line of each test case contains integers ().
Output
For each test case, first output Yes if a solution exists or No if no solution exists. You may print each character in either case, for example YES and yEs will also be accepted.
Only when there is a solution, output integers on the second line. The -th number should be either or . represents that the element belongs to sequence and represents that the element belongs to sequence .
You should guarantee that and both appear at least once.
Note
In the first test case, and . You can verify .
In the second test case, it is impossible to find a solution. For example, suppose you distributed the first elements to array and then the last element to array . You have and , but . Hence it is invalid.
