Consider a game with n players and n chairs. The chairs will be arranged in a circle, and each player will sit on a chair. There is also a bell which will ring some number of times during the game.
Each chair has an integer between 1 and n: the number of steps the player who sits on that chair must move clockwise when the bell rings. A chair arrangement is valid if each chair will have exactly one player after the bell rings.
Your task is to find a valid chair arrangement or state that there is no such arrangement.
Input
The first line has an integer t: the number of tests.
After this, each test consists of two lines. The first line has an integer n. The second line has integers s_1,s_2,\dots,s_n: the numbers on the chairs.
Output
For each test, first print YES
if there is a valid chair arrangement and NO
otherwise. If the answer is YES
, also print a possible arrangement clockwise. If there are several valid arrangements, you can print any of them.
Constraints
- 1 \le t \le 1000
- 1 \le n \le 100
