The first line contains an integerT(1 ≤ T ≤ 100) specifying the number of test cases. The first line of each test case contains an integern(1 ≤ n ≤ 105), in whichnis the size of arraya. Then a line follows containingnintegersa1, ..., an(1 ≤ ai...

The array becomes [1,2,−3,4] with prefix sums equal to [1,3,0,4]. In the third and fourth examples, a1+a2+⋯+am is already the smallest of the prefix sums — no operation needs to be performed. In the fifth example, a valid sequence of operations is: a3:=−a3, a2:=...
