CF1862G.The Great Equalizer

Tema bought an old device with a small screen and a worn-out inscription "The Great Equalizer" on the side.

The seller said that the device needs to be given an array $a$ of integers as input, after which "The Great Equalizer" will work as follows:

1. Sort the current array in non-decreasing order and remove duplicate elements leaving only one occurrence of each element.
2. If the current length of the array is equal to $1$ , the device stops working and outputs the single number in the array — output value of the device.
3. Add an arithmetic progression { $n,\ n - 1,\ n - 2,\ \ldots,\ 1$ } to the current array, where $n$ is the length of the current array. In other words, $n - i$ is added to the $i$ -th element of the array, when indexed from zero.
4. Go to the first step.

To test the operation of the device, Tema came up with a certain array of integers $a$ , and then wanted to perform $q$ operations on the array $a$ of the following type:

1. Assign the value $x$ ( $1 \le x \le 10^9$ ) to the element $a_i$ ( $1 \le i \le n$ ).
2. Give the array $a$ as input to the device and find out the result of the device's operation, while the array $a$ remains unchanged during the operation of the device.

Help Tema find out the output values of the device after each operation.

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 $2 \cdot 10^5$ .

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

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: $$ [6, 10, 1] \rightarrow [1, 6, 10] \rightarrow [4, 8, 11] \rightarrow [7, 10, 12] \rightarrow [10, 12, 13] \rightarrow [13, 14, 14] \rightarrow [13, 14] \rightarrow [15, 15] \rightarrow [15] $$$$
