Problem DescriptionGive you a scale and some goods. You should put all the goods on two sides of scale and make the scales balanced. InputThe first line contains an integer T which is the number of test case.For each test case, there are two lines of data. In the first line, there is a single integer n which describes the number of goods. In the second line, there are n integers. The i-th integer wi is the weight of the i-th corresponding goods. (0 < T ≤ 10, 0 < n ≤ 100, 0 < wi ≤ 100) OutputFor each test case, if all the goods can be put on the scale and make the scales balanced at the same time, output “Yes”, otherwise output “No”.
