K closest elements

Given a sorted array of numbers, value K and an index X in array, find the K closest numbers in position to X in array.

Example: Let array be 11 23 24 75 89, X be 24 and K be 2. Now we have to find K numbers closest to X that is 24. In this example, 23 and 75 are the closest 2 numbers to 24.

Note: K should be even and in cases with less than k/2 elements on left side or right side, we need to print other side elements. Like 2 4 5 6 7, X be 6 and K be 4 then answer is 2 4 5 7



The first line of input contains an integer T denoting the number of test cases.
The first line of each test case is N,N is the size of array.
The second line of each test case contains N input C[i].
The third line of each test case contains K and X.


Print K closest number in position to X in array.


1 ≤ T ≤ 100
1 ≤ N ≤ 100
1 ≤ C[i] ≤ 1000


11 23 24 75 89
2 24

23 75
