The first line will be an integer T, which is the number of test cases. (1 <= T <= 10). For each test case, the first line will be an integer n(1 <= n <= 106), then the second line will be n integers, they make up the initial set. The third line will be an integer q(1 <= q <= 105), it means the number of operations. Then followed by q lines, each line will be one of the following cases:

2: Delete.

3: Query.
