B'The only difference between the two versions is that in this version, the constraints are lower. Initially, array a contains just the number 1 . You can perform several operations in order to change the array. In an operation, you can select some subsequence ^{ dagger} of a and add into a an element equal to the sum of all elements of the subsequence. You are given a final array c . Check if c can be obtained from the initial array a by performing some number (possibly 0) of operations on the initial array. ^{ dagger} A sequence b is a subsequence of a sequence a if b can be obtained from a by the deletion of several (possibly zero, but not all) elements. In other words, select k ( 1 <= q k <= q |a| ) distinct indices i_1, i_2, ... , i_k and insert anywhere into a a new element with the value equal to a_{i_1} + a_{i_2} + ... + a_{i_k} . The first line of the input contains an integer t ( 1 <= q t <= q 1000 ) -- the number of test cases. The description of the test cases follows. The first line of each test case contains a single integer n ( 1 <= q n <= q 5000 ) -- the number of elements the final array c should have. The second line of each test case contains n space-separated integers c_i ( 1 <= q c_i <= q 5000 ) -- the elements of the final array c that should be obtained from the initial array a . It is guaranteed that the sum of n over all test cases does not exceed 5000 . For each test case, output "YES" (without quotes) if such a sequence of operations exists, and "NO" (without quotes) otherwise. You can output the answer in any case (for example, the strings "yEs", "yes", "Yes" and "YES" will be recognized as a positive answer). For the first test case, the initial array a is already equal to [1] , so the answer is "YES". For the second test case, performing any a'...
