( 17871 ) B 378QAQ and Mocha's Array PROGRAMMING brute force greedy math sortings 1000

B'Mocha likes arrays, so before her departure, 378QAQ gave her an array a consisting of n positive integers as a gift. Mocha thinks that a is beautiful if there exist two numbers i and j ( 1 <= q i,j <= q n , i neq j ) such that for all k ( 1 <= q k <= q n ), a_k is divisible ^ dagger by either a_i or a_j . Determine whether a is beautiful. ^ dagger x is divisible by y if there exists an integer z such that x = y cdot z . Each test contains multiple test cases. The first line contains the number of test cases t ( 1 <= q t <= q 500 ). The description of the test cases follows. The first line of each test case contains a single integer n ( 3 <= q n <= q 10^5 ) -- the length of the array a . 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 . It is guaranteed that the sum of n over all test cases does not exceed 10^5 . For each test case, output "Yes" if array a is beautiful, and output "No" otherwise. You can output "Yes" and "No" in any case (for example, strings "yEs", "yes", "Yes" and "YES" will be recognized as a positive response). In the first test case, any two numbers in the array are coprime, so the answer is "No". In the second test case, we can pick i=2 and j=1 . Since every number in the array is divisible by a_i = 1 , the answer is "Yes". In the third test case, we can pick i=3 and j=5 . 2 and 4 is divisible by a_i = 2 while 3 , 6 and 12 is divisible by a_j = 3 , so the answer is "Yes". '...
