## 문제

Two robots, Carl and Clara, are a part of a secret network designed to pass messages.

Robot Clara has got a secret message. The message has a form of a black-and-white rectangle of $r$ rows and $c$ columns which contains $r \times c$ pixels. Each pixel is characterized by brightness: an integer from $0$ to $255$ (a byte) where $0$ is black, $255$ is white, and the numbers in between correspond to different shades of gray.

Clara does not know whether the message has some hidden meaning, but it definitely looks like "white noise": each pixel can be considered to have a random value which is independent from other pixels and uniformly distributed among the $256$ possible colors.

Clara's job is to answer questions by robot Carl. Each question is formulated as a small black-and-white rectangle. The answer is the coordinates of that rectangle in the original message.

However, before answering questions, Clara has to delete the message. Unfortunately, her memory is limited to a mere $400$ kibibytes, so the message may not fit there...

How should Clara act to nevertheless answer all the questions correctly?

## 인터랙션

In this problem, your solution will be run twice on each test. Each line of input is terminated by an end-of-line character.

In input and output, bytes are integers from $0$ to $255$ inclusive, and they are represented in hexadecimal form: each byte is recorded by exactly two characters, and each of these characters is either a digit 0--9 or an uppercase letter A--F.

## 첫 번째 실행

During the first run, the solution gets the message and fills Clara's memory. The first line contains the word "message". The second line contains two space-separated integers $r$ and $c$: the number of rows and columns in the message ($20 \le r, c \le 2000$). Each of the next $r$ lines contains $c$ space-separated bytes: the message itself. The bytes are picked in advance, independently of each other, by a pseudorandom number generator, and all values from the range $0$--$255$ are equally probable.

On the first line, print an integer $m$, the size of the record in Clara's memory ($0 \le m \le 409\,600$). On the second line, print $m$ space-separated bytes: the contents of that record.

## 두 번째 실행

During the second run, the solution receives the record in Clara's memory, and then answers Carl's questions. The first line contains the word "parts". The second line contains an integer $m$, the size of the record in Clara's memory ($0 \le m \le 409\,600$). The third line contains $m$ space-separated bytes: the contents of that record. These two lines repeat what the solution printed during the first run.

The next line contains an integer $q$, the number of Carl's questions ($1 \le q \le 10\,000$). Then the questions follow. Each question starts with a line containing two integers $h$ and $w$: the number of rows and columns in the question's rectangle ($10 \le h, w \le 20$). Each of the next $h$ lines contains $w$ space-separated bytes: the contents of the rectangle. It is guaranteed that each given rectangle can be uniquely located in the original message. The questions are fixed in advance and do not depend on the results of the first run.

For each question, print a line containing two integers: the row and column in the original message which correspond to the location of the upper left corner of the question's rectangle. The rows are numbered $1$ to $r$ from top to bottom, and the columns are numbered $1$ to $c$ from left to right.

## 예제

For each test, the input during the second run depends on the solution's output during the first run.
