题目描述

An array aa is called ugly if it contains at least one element which is equal to the sum of all elements before it. If the array is not ugly, it is beautiful.

For example:

  • the array [6,3,9,6][6, 3, 9, 6] is ugly: the element 99 is equal to 6+36 + 3 ;
  • the array [5,5,7][5, 5, 7] is ugly: the element 55 (the second one) is equal to 55 ;
  • the array [8,4,10,14][8, 4, 10, 14] is beautiful: 808 \ne 0 , 484 \ne 8 , 108+410 \ne 8 + 4 , 148+4+1014 \ne 8 + 4 + 10 , so there is no element which is equal to the sum of all elements before it.

You are given an array aa such that 1a1a2an1001 \le a_1 \le a_2 \le \dots \le a_n \le 100 . You have to reorder the elements of aa in such a way that the resulting array is beautiful. Note that you are not allowed to insert new elements or erase existing ones, you can only change the order of elements of aa . You are allowed to keep the array aa unchanged, if it is beautiful.

输入格式

The first line contains one integer tt ( 1t20001 \le t \le 2000 ) — the number of test cases.

Each test case consists of two lines. The first line contains one integer nn ( 2n502 \le n \le 50 ). The second line contains nn integers a1,a2,,ana_1, a_2, \dots, a_n ( 1a1a2an1001 \le a_1 \le a_2 \le \dots \le a_n \le 100 ).

输出格式

For each test case, print the answer as follows:

  • if it is impossible to reorder the elements of aa in such a way that it becomes beautiful, print NO;
  • otherwise, in the first line, print YES. In the second line, print nn integers — any beautiful array which can be obtained from aa by reordering its elements. If there are multiple such arrays, print any of them.
