You are an expert competitive programmer. You will be given a problem statement, test case constraints and example test inputs and outputs. Please reason step by step about the solution (that must respect memory and time limits), then provide a complete implementation in c++17.

Your solution must read input from standard input (cin), write output to standard output (cout).
Do not include any debug prints or additional output.

Put your final solution within a single code block:
```cpp
<your code here>

# Problem
A transformation of an array of positive integers $$$a_1,a_2,\dots,a_n$$$ is defined by replacing $$$a$$$ with the array $$$b_1,b_2,\dots,b_n$$$ given by $$$b_i=a_i\oplus a_{(i\bmod n)+1}$$$, where $$$\oplus$$$ denotes the bitwise XOR operation.

You are given integers $$$n$$$, $$$t$$$, and $$$w$$$. We consider an array $$$c_1,c_2,\dots,c_n$$$ ($$$0 \le c_i \le 2^w-1$$$) to be bugaboo if and only if there exists an array $$$a_1,a_2,\dots,a_n$$$ such that after transforming $$$a$$$ for $$$t$$$ times, $$$a$$$ becomes $$$c$$$.

For example, when $$$n=6$$$, $$$t=2$$$, $$$w=2$$$, then the array $$$[3,2,1,0,2,2]$$$ is bugaboo because it can be given by transforming the array $$$[2,3,1,1,0,1]$$$ for $$$2$$$ times:

$$$$$$ [2,3,1,1,0,1]\to [2\oplus 3,3\oplus 1,1\oplus 1,1\oplus 0,0\oplus 1,1\oplus 2]=[1,2,0,1,1,3]; \\ [1,2,0,1,1,3]\to [1\oplus 2,2\oplus 0,0\oplus 1,1\oplus 1,1\oplus 3,3\oplus 1]=[3,2,1,0,2,2]. $$$$$$

And the array $$$[4,4,4,4,0,0]$$$ is not bugaboo because $$$4 > 2^2 - 1$$$. The array $$$[2,3,3,3,3,3]$$$ is also not bugaboo because it can't be given by transforming one array for $$$2$$$ times.

You are given an array $$$c$$$ with some positions lost (only $$$m$$$ positions are known at first and the remaining positions are lost). And there are $$$q$$$ modifications, where each modification is changing a position of $$$c$$$. A modification can possibly change whether the position is lost or known, and it can possibly redefine a position that is already given.

You need to calculate how many possible arrays $$$c$$$ (with arbitrary elements on the lost positions) are bugaboos after each modification. Output the $$$i$$$-th answer modulo $$$p_i$$$ ($$$p_i$$$ is a given array consisting of $$$q$$$ elements).

## Input Format
The first line contains four integers $$$n$$$, $$$m$$$, $$$t$$$ and $$$w$$$ ($$$2\le n\le 10^7$$$, $$$0\le m\le \min(n, 10^5)$$$, $$$1\le t\le 10^9$$$, $$$1\le w\le 30$$$).

The $$$i$$$-th line of the following $$$m$$$ lines contains two integers $$$d_i$$$ and $$$e_i$$$ ($$$1\le d_i\le n$$$, $$$0\le e_i< 2^w$$$). It means the position $$$d_i$$$ of the array $$$c$$$ is given and $$$c_{d_i}=e_i$$$. It is guaranteed that $$$1\le d_1<d_2<\ldots<d_m\le n$$$.

The next line contains only one number $$$q$$$ ($$$1\le q\le 10^5$$$) — the number of modifications.

The $$$i$$$-th line of the following $$$q$$$ lines contains three integers $$$f_i$$$, $$$g_i$$$, $$$p_i$$$ ($$$1\le f_i\le n$$$, $$$-1\le g_i< 2^w$$$, $$$11\le p_i\le 10^9+7$$$). The value $$$g_i=-1$$$ means changing the position $$$f_i$$$ of the array $$$c$$$ to a lost position, otherwise it means changing the position $$$f_i$$$ of the array $$$c$$$ to a known position, and $$$c_{f_i}=g_i$$$. The value $$$p_i$$$ means you need to output the $$$i$$$-th answer modulo $$$p_i$$$.

## Output Format
The output contains $$$q$$$ lines, denoting your answers.

## Note
In the first example, $$$n=3$$$, $$$t=1$$$, and $$$w=1$$$. Let $$$?$$$ denote a lost position of $$$c$$$.

In the first query, $$$c=[1,0,1]$$$. The only possible array $$$[1,0,1]$$$ is bugaboo because it can be given by transforming $$$[0,1,1]$$$ once. So the answer is $$$1\bmod 123\,456\,789 = 1$$$.

In the second query, $$$c=[1,1,1]$$$. The only possible array $$$[1,1,1]$$$ is not bugaboo. So the answer is $$$0\bmod 111\,111\,111 = 0$$$.

In the third query, $$$c=[?,1,1]$$$. There are two possible arrays $$$[1,1,1]$$$ and $$$[0,1,1]$$$. Only $$$[0,1,1]$$$ is bugaboo because it can be given by transforming $$$[1,1,0]$$$ once. So the answer is $$$1\bmod 987\,654\,321=1$$$.

In the fourth query, $$$c=[?,1,?]$$$. There are four possible arrays. $$$[0,1,1]$$$ and $$$[1,1,0]$$$ are bugaboos. $$$[1,1,0]$$$ can be given by performing $$$[1,0,1]$$$ once. So the answer is $$$2\bmod 555\,555\,555=2$$$.

Now solve the problem and return the code.
