write a go solution for B. The Picky Cattime limit per test1 secondmemory limit per test256 megabytesinputstandard inputoutputstandard output You are given an array of integers a_1,a_2,ldots,a_n. You are allowed to do the following operation any number of times (possibly zero):  Choose an index i (1<=i<=n). Multiply a_i by -1 (i.e., update a_i:=-a_i). Your task is to determine whether it is possible to make the element at index 1 become the median of the array after doing the above operation any number of times. Note that operations can be applied to index 1 as well, meaning the median can be either the original value of a_1 or its negation.The median of an array b_1,b_2,ldots,b_m is defined as the ceil(m/2)-th^∗ smallest element of array b. For example, the median of the array [3,1,2] is 2, while the median of the array [10,1,8,3] is 3.It is guaranteed that the absolute value of the elements of a are distinct. Formally, there are no pairs of indices 1<=i<j<=n where |a_i|=|a_j|.^∗ceil(x) is the ceiling function which returns the least integer greater than or equal to x.InputEach test contains multiple test cases. The first line contains the number of test cases t (1<=t<=10^4). The description of the test cases follows. The first line of each test case contains a single integer n (1<=n<=10^5) — the length of the array a.The second line of each test case contains n integers a_1,a_2,ldots,a_n (|a_i|<=10^6, |a_i|neq|a_j|) — the elements of the array a.It is guaranteed that the sum of n over all test cases does not exceed 10^5. OutputFor each testcase, output "YES" if it is possible to make the element at index 1 become the median of the array, and "NO" otherwise.You can output the answer in any case (upper or lower). For example, the strings "yEs", "yes", "Yes", and "YES" will be recognized as positive responses.ExampleInput732 3 151 2 3 4 544 2 0 -54-5 0 4 34-10 8 3 211109 1000 -999 -13 456 -223 23 24 10 0OutputYES

NoteIn the first test case, a_1=2 is already the median of the array a=[2,3,1], so no operation is required.In the second test case, we can do two operations: one on index 2, and one on index 5. The array becomes [1,-2,3,4,-5], which has a median of 1.In the third test case, if you do an operation on index 1, the array will become [-4,2,0,-5], which has a median of -4.In the fourth test case, it can be proven that no sequence of operations can make the median of the array become 5 or -5.. Output only the code with no comments, explanation, or additional text.
