B'You are given an array a consisting of n integers, as well as an array b consisting of m integers. Let text{LIS}(c) denote the length of the longest increasing subsequence of array c . For example, text{LIS}([2, underline{1}, 1, underline{3}]) = 2 , text{LIS}([ underline{1}, underline{7}, underline{9}]) = 3 , text{LIS}([3, underline{1}, underline{2}, underline{4}]) = 3 . You need to insert the numbers b_1, b_2, ldots, b_m into the array a , at any positions, in any order. Let the resulting array be c_1, c_2, ldots, c_{n+m} . You need to choose the positions for insertion in order to minimize text{LIS}(c) . Formally, you need to find an array c_1, c_2, ldots, c_{n+m} that simultaneously satisfies the following conditions: Each test contains multiple test cases. The first line contains a single integer t (1 <= q t <= q 10^4) -- the number of test cases. The description of the test cases follows. The first line of each test case contains two integers n, m (1 <= q n <= q 2 cdot 10^5, 1 <= q m <= q 2 cdot 10^5) -- the length of array a and the length of array b . The second line of each test case contains n integers a_1, a_2, ldots, a_n (1 <= q a_i <= q 10^9) -- the elements of the array a . The third line of each test case contains m integers b_1, b_2, ldots, b_m (1 <= q b_i <= q 10^9) -- the elements of the array b . It is guaranteed that the sum of n over all test cases does not exceed 2 cdot 10^5 , and the sum of m over all test cases does not exceed 2 cdot 10^5 . For each test case, output n + m numbers -- the elements of the final array c_1, c_2, ldots, c_{n+m} , obtained after the insertion, such that the value of text{LIS}(c) is minimized. If there are several answers, you can output any of them. In the first te'...
