Skylar is LowbieH's best friend, so every day LowbieH gives Skylar
a gift. Specifically, LowbieH will give Skylar a gift of value
\(v_i\) in day i. Now Skylar wants to know the median of gift values
on the odd days, specifically, on the first day, and the third day, the fifth
day ... Can you help her to solve it?
The first line will be an integer T(1 <= T <= 10), which is the number of test cases.
For each test case, the first will be an integer n. Then there will be n integers, represeenting the gift values \(v_1\), ... ,\(v_n\). ( 1 <= n <= 300000, 0 <= \(v_i\) <= 300000)
For each test case, output the median gift
values every odd days.
