One night, Mark realized that there is an essay due tomorrow. He hasn't written anything yet, so Mark decided to randomly copy-paste substrings from the prompt to make the essay.

More formally, the prompt is a string $$$s$$$ of initial length $$$n$$$. Mark will perform the copy-pasting operation $$$c$$$ times. Each operation is described by two integers $$$l$$$ and $$$r$$$, which means that Mark will append letters $$$s_l s_{l+1} \ldots s_r$$$ to the end of string $$$s$$$. Note that the length of $$$s$$$ increases after this operation.

Of course, Mark needs to be able to see what has been written. After copying, Mark will ask $$$q$$$ queries: given an integer $$$k$$$, determine the $$$k$$$-th letter of the final string $$$s$$$.

Input

The first line contains a single integer $$$t$$$ ($$$1\leq t\leq 1000$$$) — the number of test cases.

The first line of each test case contains three integers $$$n$$$, $$$c$$$, and $$$q$$$ ($$$1\leq n\leq 2\cdot 10^5$$$, $$$1\leq c\leq 40$$$, and $$$1\leq q\leq 10^4$$$) — the length of the initial string $$$s$$$, the number of copy-pasting operations, and the number of queries, respectively.

The second line of each test case contains a single string $$$s$$$ of length $$$n$$$. It is guaranteed that $$$s$$$ only contains lowercase English letters.

The following $$$c$$$ lines describe the copy-pasting operation. Each line contains two integers $$$l$$$ and $$$r$$$ ($$$1\leq l\leq r\leq 10^{18}$$$). It is also guaranteed that $$$r$$$ does not exceed the current length of $$$s$$$.

The last $$$q$$$ lines of each test case describe the queries. Each line contains a single integer $$$k$$$ ($$$1\leq k\leq 10^{18}$$$). It is also guaranteed that $$$k$$$ does not exceed the final length of $$$s$$$.

It is guaranteed that the sum of $$$n$$$ and $$$q$$$ across all test cases does not exceed $$$2\cdot 10^5$$$ and $$$10^4$$$, respectively.

Output

For each query, print the $$$k$$$-th letter of the final string $$$s$$$.

Note

In the first test case, the copy-paste process is as follows.

The first step is pasting string $$$\texttt{mark}$$$ at the end, yielding the string $$$\texttt{mark}\color{red}{\texttt{mark}}$$$.
The second step is pasting string $$$\texttt{mar}$$$ at the end, yielding the string $$$\texttt{markmark}\color{red}{\texttt{mar}}$$$.
The third step is pasting string $$$\texttt{rkmark}$$$ at the end, yielding the string $$$\texttt{markmarkmar}\color{red}{\texttt{rkmark}}$$$.

In the second test case, the copy-paste process is as follows.

The first step is pasting string $$$\texttt{re}$$$ at the end, yielding the string $$$\texttt{creamii}\color{red}{\texttt{re}}$$$.
The second step is pasting string $$$\texttt{ea}$$$ at the end, yielding the string $$$\texttt{creamiire}\color{red}{\texttt{ea}}$$$.
The third step is pasting string $$$\texttt{reamiire}$$$ at the end, yielding the string $$$\texttt{creamiireea}\color{red}{\texttt{reamiire}}$$$.
