The Great Equalizer

Description:

Input:

The first line of the input contains a single integer $$$t$$$ ($$$1 \le t \le 10^4$$$) — the number of test cases.

Then follows the description of each test case.

The first line of each test case contains a single integer $$$n$$$ ($$$1 \le n \le 2 \cdot 10^5$$$) — the size of the array $$$a$$$ that Tema initially came up with.

The second line of each test case contains $$$n$$$ integers $$$a_1, a_2, a_3, \ldots, a_n$$$ ($$$1 \le a_i \le 10^9$$$) — the elements of the array $$$a$$$.

The third line of a set contains a single integer $$$q$$$ ($$$1 \le q \le 2 \cdot 10^5$$$) — the number of operations.

Each of the next $$$q$$$ lines of a test case contains two integers $$$i$$$ ($$$1 \le i \le n$$$) and $$$x$$$ ($$$1 \le x \le 10^9$$$) - the descriptions of the operations.

It is guaranteed that the sum of the values of $$$n$$$ and the sum of the values of $$$q$$$ for all test cases do not exceed $$$2 \cdot 10^5$$$.

Output:

For each test case, output $$$q$$$ integers — the output values of the device after each operation.

Note:

Let's consider the first example of the input.

Initially, the array of numbers given as input to the device will be $$$[6, 4, 8]$$$. It will change as follows: $$$$$$[6, 4, 8] \rightarrow [4, 6, 8] \rightarrow [7, 8, 9] \rightarrow [10, 10, 10] \rightarrow [10]$$$$$$

Then, the array of numbers given as input to the device will be $$$[6, 10, 8]$$$. It will change as follows: $$$$$$[6, 10, 8] \rightarrow [6, 8, 10] \rightarrow [9, 10, 11] \rightarrow [12, 12, 12] \rightarrow [12]$$$$$$

The last array of numbers given as input to the device will be $$$[6, 10, 1]$$$. It will change as follows: $$$$$$[6, 10, 1] \rightarrow [1, 6, 10] \rightarrow [4, 8, 11] \rightarrow [7, 10, 12] \rightarrow [10, 12, 13] \rightarrow [13, 14, 14] \rightarrow [13, 14] \rightarrow [15, 15] \rightarrow [15]$$$$$$
