Problem Statement :
If an array a contains at least one element that is equal to the sum of all elements before it, it is said to be ugly. The array is beautiful if it is not ugly.
As an example:
The array [6,3,9,6] is ugly because the element 9 is equal to 6+3; the array [5,5,7] is ugly because the element 5 (the second one) is equal to 5; the array [8,4,10,14] is beautiful because the element 9 is equal to 6+3; There are no elements that are equal to the sum of all elements preceding it: 80, 48, 108+4, 1484+4+10.
You are given an array a with the value 1a11a2an100. You must reorder the elements of a so that the resulting array looks nice. It should be noted that you are not permitted to add new elements or
Format of Input :
The first line contains a single integer t (1t2000) indicating the number of test cases.
Evey test case is made up of two lines. The first line has a single integer n (2n50). The second line has n integers a1,a2,...,an (1a12an100).
Format of the Output :
Print the following answer for each test case:
If rearranging the elements of an in such a way that it becomes beautiful is impossible, print NO; otherwise, print YES in the first line. Print n integers — any beautiful array that can be obtained from a by reordering its elements — in the second line. If there are multiple arrays of this type, print any of them.
