( 618 ) F Bipartite Array PROGRAMMING dp

B'You are given a permutation p consisting of n integers 1, 2, ... , n (a permutation is an array where each element from 1 to n occurs exactly once). Let 's call an array a bipartite if the following undirected graph is bipartite: Your task is to find a bipartite array of integers a of size n , such that a_i = p_i or a_i = -p_i , or report that no such array exists. If there are multiple answers, print any of them. The first line contains a single integer t ( 1 <= t <= 2 cdot 10^5 ) -- the number of test cases. The first line of each test case contains a single integer n ( 1 <= n <= 10^6 ) -- the size of the permutation. The second line contains n integers p_1, p_2, ... , p_n . The sum of n over all test cases doesn 't exceed 10^6 . For each test case, print the answer in the following format. If such an array a does not exist, print "NO" in a single line. Otherwise, print "YES" in the first line and n integers -- array a in the second line. '...
