( 327 ) K Make Triangle PROGRAMMING constructive algorithms math

B'You are given n positive integers x_1, x_2, ldots, x_n and three positive integers n_a, n_b, n_c satisfying n_a+n_b+n_c = n . You want to split the n positive integers into three groups, so that: Determine if this is possible. If this is possible, find one way to do so. Each test contains multiple test cases. The first line contains an integer t ( 1 <= t <= 100 ,000 ) -- the number of test cases. The descriptions of the t test cases follow. The first line of each test case contains the integers n, n_a, n_b, n_c ( 3 <= q n <= q 200 ,000, 1 <= q n_a,n_b,n_c <= q n-2, n_a+n_b+n_c = n ) -- the number of integers to split into three groups, and the desired sizes of the three groups. The second line of each test case contains n integers x_1, x_2, ldots, x_n ( 1 <= q x_i <= q 10^{9} ). It is guaranteed that the sum of n over all test cases does not exceed 200 ,000 . For each test case, print texttt{YES} if it is possible to split the numbers into three groups satisfying all the conditions. Otherwise, print texttt{NO} . If such a split exists, then describe the three groups as follows. On the next line, print n_a integers a_1, a_2, ldots, a_{n_a} -- the numbers in the first group. On the next line, print n_b integers b_1, b_2, ldots, b_{n_b} -- the numbers in the second group. On the next line, print n_c integers c_1, c_2, ldots, c_{n_c} -- the numbers in the third group. These n_a+n_b+n_c=n integers should be a permutation of x_1, x_2, ldots, x_n , and they should satisfy the conditions from the statement. If there are multiple solutions, print any of them. In the first test case, we can put two 1 s into each group: the sum in each group would be 2 , and there exists a triangle with positive area and sides 2 , 2 , 2 . In the second and third test cases, it can be shown that there is '...
