- Output:
    - Ciphertext: Uppercase letters string.
- Preparation:
    - 5x5 grid (There is no letter J.Its row and column coordinates are between 0 and 4.):

        N  T  C  D  E
        F  G  H  K  M
        O  P  Q  R  S

- Encryption Steps:
    - Remove punctuation, spaces, and the letter J from plaintext.
    - For each letter p in the plaintext, find its corresponding row and column coordinates (between 0 and 4) in the grid. For example, A is (0,4).
    - Arrange all row and column coordinates, read all row coordinates first, then read all column coordinates to form a new coordinate sequence. For example, the original has (0,4)(1,2), now read as 0142.
    - Each time, two numbers are taken out from the new coordinate sequence as new row and column coordinates, and the corresponding letters are found in the grid to form the ciphertext. For example, for 0142, the ciphertext corresponding to (0,1) is B, and the ciphertext corresponding to (4,2) is X. The final ciphertext is BX.

    - Divide the coordinate sequence into two halves, the first half is all the original row coordinates, the second half is all the original column coordinates, read one from the original row coordinates, read one from the original column coordinates, and find the corresponding letter in the grid according to the original row and column coordinates to form the plaintext.
        - For example [0,1,4,2], the first half as row coordinates: [0, 1], the second half as column coordinates: [4,2].
        - Read one from the row coordinates, one from the column coordinates, and so on alternately. Obtain (0,4),(1,2), respectively, and find the corresponding letters in the grid as AC.

- Encryption Steps:
    - The plaintext is grouped into blocks of 5 characters, numbered from 0.
    - For blocks of 5 characters:
        - To use the grid is determined by calculating grid_index = (i // 5) % 8, where i is the number. Integer division operator // divides the number on the left by the number on the right, rounding down the result. That is, it removes the fractional part and keeps only the integer part!This ensures that the grid is recycled.
        - For each character in the current block:
            - If the character is "J", it is not encrypted and is appended directly to the encrypted block.
            - Otherwise, find the position of the character in the current grid. Then move one grid position to the lower right (row+1,col+1) (or continue on the opposite side of the corresponding boundary if it crosses the boundary), and get the letter at the position after the move as the encrypted letter.
            - Add the encrypted letter to the encryption block.
    - After processing all the blocks, connect the encrypted blocks to form the final encrypted message.

        - For example, if the cipher text is "KHOORTQHQTHHSAUQ", the 0th block is "KHOOR", the 1st block is "TQHQH", and so on. (Numbering starts at 0)
    - Determine the grid used for the current block:
    Calculate grid_index = (i // 5) % 8 to select the appropriate grid from the grid list. i is the block number.
    - For each character in the block:
        - If the character is "J": add "J" directly to the decrypted block without decryption.
        - Otherwise find the position of the character in the grid and obtain it by moving one grid to the upper left (or continue on the opposite side of the corresponding boundary if it crosses the boundary). the letter at the position after the move is used as the decrypted letter.
        - Append the decrypted letter to the decryption block.
    - After processing all characters in the block, append the decrypted block to the decrypted message list. Form the final decrypted message.

**Encryption Rules:**

- Input:
    - Plaintext: Uppercase letters string without punctuation and spaces.
- Output:
    - Ciphertext: A numeric string without punctuation and spaces.
- Preparation:
    - 3 Girds(All row and column numbers are counted from 0.):
        - Grid 1 (3x9):

            Q W E R T Y U I O
            P A S D F G H J K
            L Z X C V B N M #

        - Grid 2 (9x3):

            Q W E
            R T Y
            U I O
            P A S
            D F G
            H J K
            L Z X
            C V B
            N M #

        - Grid 3 (3x3):

            1 2 3
            4 5 6
            7 8 9

- Encryption Steps:
    - Remove all spaces and punctuation from the plain text and convert them to capital letters.
    - Cut the plaintext into groups of 6 characters, and if a group is less than 6 characters long, fill it with `#`.
    - Split each group of 6 characters into 3 binary groups.
    - For each binary group `(L1, L2)` do the following:
        - Determine the row and column numbers  of `L1` in `grid1` as `(l1_row, l1_col)`.
        - Determine the row and column numbers of `L2` in `grid2` as `(l2_row, l2_col)`.
        - Find the corresponding number `num3` in `grid3` from `l1_row` and `l2_col`.
        - Output the triple `(l1_col, num3, l2_row)` of the three numbers.
            - For example, for the binary (T,H), the row and column numbers of T in `grid1` are (0,4), the row and column numbers of H in `grid2` are (5,0).
            - Based on `l1_row` (0) and `l2_col`(0) , the corresponding number `num3` found in `grid3` is 1, and the final ternary is (4, 1, 5).
    - After performing the previous step multiple times and converting all the binary groups to triples, read them in turn to form a string of numbers that can be used as encrypted information. For example (4, 1, 5), (2, 3, 3), (8, 1, 8), the final encrypted message is 415233818.

 **Decryption Rules:**

- Input:
    - Ciphertext: A numeric string without punctuation and spaces.
- Output:
    - Plaintext: Uppercase letters string without punctuation and spaces.
- Preparation:
    - 3 Girds (Same as encryption)
- Decryption Steps (exact opposite of encryption steps):
    - Divide the ciphertext into triples of three numbers.
    - For each ternary `(x, y, z)` do the following:
        - Find the row number of y in Gird3 where the value of L1_row is equal to the row number;
        - Find the column number of y in Gird3, with the value of L2_col equal to that column number;
        - The value of L1_col is equal to x, the value of L2_row is equal to z.
        - Find the corresponding letter p1 in Gird1 according to the determined (L1_row,L1_col).
        - Based on the determined (L2_row,L2_col), find the corresponding letter p2 in Gird2.
        - p1p2 is the decrypted message of the triad.
        - For example, for the ternary (4,1,5), in Gird3, the row number corresponding to 1 is 0, so L1_row=0, in Gird3, the column number corresponding to 1 is 0, so L2_col=0. L1_col=4, L2_row=5. According to (0,4) in Gird1, we find the corresponding letter T, and according to (5,0) in Gird2, we decrypt all the ternaries to get the letter p2 p1p2 as the message after decrypting the ternary. We find the corresponding letter H in Gird2 according to (5,0), so the final decryption is TH.
    - String all the decrypted messages together, remove the `#` at the end (these characters are padding characters added to make the message length a multiple of 6), to form the decrypted plaintext.

请根据加密算法对明文进行加密
元素周期表加密是将明文字母映射到元素周期表中相应元素的原子序号的方法。每个字母可以对应多个元素，加密者需要选择一个规则来决定映射到哪个元素。空格可以不映射或用一个特定的数字表示，如"0"。加密后的密文是这些原子序号的序列。

具体步骤如下：
1. 选择字母序列：决定用于加密的字母序列，例如谜题中的文字。
2. 映射到元素序号：将字母映射到对应的元素序号。若有多个元素的首字母相同，则随机选择一个元素进行映射。
3. 生成密文：将映射后的数字串联起来得到密文。

Please encrypt the plaintext according to the encryption algorithm. The periodic table encryption method maps plaintext letters to the atomic numbers of corresponding elements in the periodic table. Each letter can correspond to multiple elements, and the encryptor needs to choose a rule to determine which element to map to. Spaces can either not be mapped or represented by a specific number, such as "0". The encrypted ciphertext is a sequence of these atomic numbers.

The specific steps are as follows:
1. Select the letter sequence: Decide on the letter sequence to be used for encryption, such as the text in the puzzle.
2. Map to element numbers: Map the letters to the corresponding element numbers. If multiple elements have the same initial letter, randomly select an element for mapping.
3. Generate ciphertext: Concatenate the mapped numbers to get the ciphertext.

### Autokey Cipher 加密方法概述

Autokey Cipher是一种流密码技术，它使用一个初始密钥和明文本身的一部分来生成一个动态的、较长的密钥用于加密。这种方法可以提高安全性，因为每次加密使用的密钥都不同。

### 加密过程简化解释

1. **去除空格**：首先从明文中移除所有的空格，确保明文是连续的字母序列。

2. **构造实际密钥**：开始时有一个初始密钥（可以是任意长度），然后将明文直接附加到这个初始密钥之后，创建一个与明文等长的“实际密钥”。这意味着，如果初始密钥较短，明文将被用作密钥的扩展部分。

3. **字符映射**：在Autokey Cipher中，通常会使用一个简单的映射，即a=0, b=1, ..., z=25，用来将字母转换为数字，方便计算。

4. **生成密文**：对于明文中的每个字母，根据其位置找到对应的“实际密钥”中的字母。然后，将这两个字母所代表的数字相加（如果结果大于等于26，则减去26以保持在字母表范围内）。最后，将得到的数值再转换回字母，这就是该位置上对应的密文字符。

5. **拼接密文**：重复上述过程直到处理完所有明文字母，并将所有获得的密文字符连接起来形成最终的密文。

Please encrypt the plaintext according to the encryption algorithm.

### Overview of Autokey Cipher Encryption Method

Autokey Cipher is a stream cipher technique that uses an initial key and a portion of the plaintext itself to generate a dynamic, longer key for encryption. This method can enhance security as the key used for encryption varies each time.

### Simplified Explanation of the Encryption Process

1. **Remove Spaces**: Firstly, remove all spaces from the plaintext to ensure that the plaintext is a continuous sequence of letters.

2. **Construct Actual Key**: Initially, there is an initial key (which can be of any length), and then the plaintext is directly appended to this initial key, creating an "actual key" that is as long as the plaintext. This means that if the initial key is short, the plaintext will be used as the extension part of the key.

3. **Character Mapping**: In Autokey Cipher, a simple mapping is usually used, i.e., a=0, b=1, ..., z=25, to convert letters into numbers for easy calculation.

4. **Generate Ciphertext**: For each letter in the plaintext, find the corresponding letter in the "actual key" according to its position. Then, add the numbers represented by these two letters (if the result is greater than or equal to 26, subtract 26 to stay within the range of the alphabet). Finally, convert the obtained value back into a letter, which is the corresponding ciphertext character at that position.

5. **Concatenate Ciphertext**: Repeat the above process until all plaintext letters are processed, and connect all the obtained ciphertext characters to form the final ciphertext.

    Row 1: abcdefghijklmnopqrstuvwxyz
    Row 2: bcdefghijklmnopqrstuvwxyza
    Row 3: cdefghijklmnopqrstuvwxyzab
    ...
    Row 26: zabcdefghijklmnopqrstuvwxy

    加密步骤如下：

    2. 表格查找：
       - 找到明文字母在字母表中的位置（行索引）。
       - 在该行中查找密钥字母的列索引。
       - 在第一行中定位列索引对应的字母，将其作为密文字母。
    3. 按照上述规则逐字处理明文，最终生成完整的密文。

    注意：如果明文中包含非字母字符，它们将直接原样添加到密文中。

Please encrypt the plaintext according to the encryption algorithm.

The Beaufort Cipher is an encryption algorithm based on substitution, and its encryption process relies on a letter table. The letter table is a 26x26 matrix, each row of which is the result of cyclically offsetting from a letter in the alphabet.

The structure of the table is as follows:
Row 1: abcdefghijklmnopqrstuvwxyz
Row 2: bcdefghijklmnopqrstuvwxyza
Row 3: cdefghijklmnopqrstuvwxyzab
...
Row 26: zabcdefghijklmnopqrstuvwxy

The encryption steps are as follows:
1. Choose a key: Determine a key to guide the encryption process, each letter will be matched with the plaintext character in turn.
2. Table lookup:
   - Find the position of the plaintext letter in the alphabet (row index).
   - Find the column index of the key letter in that row.
   - Locate the letter corresponding to the column index in the first row and use it as the ciphertext letter.
3. Process the plaintext letter by letter according to the above rules to finally generate the complete ciphertext.

Note: If the plaintext contains non-alphabet characters, they will be directly added to the ciphertext as they are.


Please encrypt the plaintext according to the encryption algorithm.

    Encryption Rules
    1. **Character Replacement**: Replace the letters in the original text according to the given letter pair mapping rules. For example, replace the letter 'V' with 'I', 'I' with 'V', and so on. Note: The case of the letters will be swapped, while other characters (such as spaces, punctuation marks) remain unchanged.
    - Letter Pair Mapping Table
    {
    'V': 'I', 'I': 'V', 'J': 'W', 'W': 'J', 'E': 'R', 'R': 'E',
    'U': 'H', 'H': 'U', 'B': 'O', 'O': 'B', 'L': 'Y', 'Y': 'L',
    'Q': 'D', 'D': 'Q', 'A': 'N', 'N': 'A', 'G': 'T', 'T': 'G',
    'F': 'S', 'S': 'F', 'X': 'K', 'K': 'X', 'Z': 'M', 'M': 'Z',
    'P': 'C', 'C': 'P',
    'v': 'i', 'i': 'v', 'j': 'w', 'w': 'j', 'e': 'r', 'r': 'e',
    'u': 'h', 'h': 'u', 'b': 'o', 'o': 'b', 'l': 'y', 'y': 'l',
    'q': 'd', 'd': 'q', 'a': 'n', 'n': 'a', 'g': 't', 't': 'g',
    'f': 's', 's': 'f', 'x': 'k', 'k': 'x', 'z': 'm', 'm': 'z',
    'p': 'c', 'c': 'p'
}
    2. **Hexadecimal ASCII Encoding**: Convert the replaced text into ASCII codes represented in hexadecimal. Each character's ASCII code is represented in hexadecimal. For example, the ASCII code for the letter 'H' is 72, which is '48' in hexadecimal.
    3. **Output the Encrypted Result**: Finally, return the encrypted message in hexadecimal format.

    棋盘密码（Polybius Square Cipher）是一种将字母编码成符号对的方法。它使用一个5行5列的网格，网格中包含26个英文字母，其中I和J在同一个格中。相应字母用数对表示。在古代，这种棋盘密码被广泛使用。Polybius校验表如下：

    1 2 3 4 5
    1 A B C D E
    2 F G H I/J K
    3 L M N O P
    4 Q R S T U
    5 V W X Y Z

    棋盘密码的加密过程非常简单，对于一个需要解码的英文字符串，首先将每个字母转换成大写，然后按照校验表中的元素对应：A对应11，B对应12...Z对应55（I和J都对应24），就可以将英文字符串加密成一个长度为2倍、由数字组成的密文。

Please encrypt the plaintext according to the encryption algorithm.

The Polybius Square Cipher is a method of encoding letters into pairs of symbols. It uses a 5x5 grid that contains 26 English letters, with I and J in the same cell. The corresponding letters are represented by pairs of numbers. In ancient times, this type of cipher was widely used. The Polybius check table is as follows:

1 2 3 4 5
1 A B C D E
2 F G H I/J K
3 L M N O P
4 Q R S T U
5 V W X Y Z

The encryption process of the Polybius Square Cipher is very simple. For an English string that needs to be decoded, first convert each letter to uppercase, then correspond to the elements in the check table: A corresponds to 11, B corresponds to 12...Z corresponds to 55 (I and J both correspond to 24), and you can encrypt the English string into a ciphertext composed of numbers twice the length.

Then, add the numbers represented by these two letters (if the result is greater than or equal to 26, subtract 26 to stay within the alphabet range). Finally, convert the resulting number back into a letter, which is the corresponding ciphertext character at that position.

5. **Concatenate Ciphertext**: Repeat the above process until all plaintext letters are processed, and connect all the obtained ciphertext characters to form the final ciphertext.

Decryption Algorithm:

The decryption process of Autokey Cipher is the reverse operation of the encryption process. Since a part of the plaintext is used to extend the key during encryption, we also need to gradually rebuild this dynamic key during decryption. Here are the simplified and clarified decryption steps based on the text you provided:

### Autokey Cipher Decryption Process

1. **Preparation**: First, prepare the ciphertext (i.e., the encrypted text) and the initial key. Make sure you know the number of ciphertext letters.

2. **Initialize Key**: Start the decryption process with the same initial key used for encryption. The initial key length is usually shorter than the final key used for encryption because it will be extended by the plaintext.

3. **Decrypt and Extend Key**:
   - For each letter Ci in the ciphertext and the currently used key letter Ki, apply the decryption formula to calculate the original plaintext letter Pi.
   - The decryption formula is: `Pi = (Ci - Ki + 26) % 26`, where `%` represents the modulus operation, ensuring the result falls between 0 and 25.
   - Convert the obtained plaintext letter Pi back into a letter and add it to the decrypted plaintext.
   - At the same time, append the just decrypted plaintext letter Pi to the key to extend the key.

4. **Repeat Decryption**: Continue to decrypt the next letter in the ciphertext and update the key according to the above steps until all ciphertexts are decrypted.

5. **Concatenate Plaintext**: When all ciphertext characters have been decrypted, concatenate all decrypted plaintext letters in order to form the complete original plaintext.

加密算法:

    棋盘密码（Polybius Square Cipher）是一种将字母编码成符号对的方法。它使用一个5行5列的网格，网格中包含26个英文字母，其中I和J在同一个格中。相应字母用数对表示。在古代，这种棋盘密码被广泛使用。Polybius校验表如下：

    1 2 3 4 5
    1 A B C D E
    2 F G H I/J K
    3 L M N O P
    4 Q R S T U
    5 V W X Y Z

    棋盘密码的加密过程非常简单，对于一个需要解码的英文字符串，首先将每个字母转换成大写，然后按照校验表中的元素对应：A对应11，B对应12...Z对应55（I和J都对应24），就可以将英文字符串加密成一个长度为2倍、由数字组成的密文。

解密算法:

    解密过程可以看成是加密过程的逆过程，由加密过程可知，密文应该是由偶数位的数字组成（如不然，舍去最后一位数字）。解密过程首先应从左到右每位数字分成一个组，再对每个组按照校验表得到2位数字对应的英文字母，再将英文字母从左往右排列即可得到明文。

    需要注意的是，与加密过程的唯一性不同，由于24这个数字既可以解密成I，又可以解密成J，加密过程可以出现不同的结果。如果把加密的映射规则看成一个函数，这个加密函数不存在逆函数。根据任务网址可以试验发现：对于PROJECT进行一次加密，再将密文进行解密，得到的结果是PROIECT。通常来说，如何确定24解密成I还是J要根据上下文确定，这需要人的工作。对于算法实现棋盘密码的加密解密过程，由在网址的实验可知：24固定解密成I。

Please decrypt the password according to the encryption and decryption algorithms.

Encryption Algorithm:

The Polybius Square Cipher is a method of encoding letters into pairs of symbols. It uses a 5x5 grid that contains 26 English letters, with I and J in the same cell. The corresponding letters are represented by pairs of numbers. This type of cipher was widely used in ancient times. The Polybius check table is as follows:

1 2 3 4 5
1 A B C D E
2 F G H I/J K
3 L M N O P
4 Q R S T U
5 V W X Y Z

The encryption process of the Polybius Square Cipher is very simple. For an English string that needs to be decoded, first convert each letter to uppercase, then correspond to the elements in the check table: A corresponds to 11, B corresponds to 12...Z corresponds to 55 (I and J both correspond to 24). This way, the English string can be encrypted into a ciphertext composed of numbers, twice the length of the original string.

Decryption Algorithm:

The decryption process can be seen as the reverse process of the encryption process. As known from the encryption process, the ciphertext should be composed of an even number of digits (if not, discard the last digit). The decryption process should first divide each digit from left to right into a group, then get the English letter corresponding to the two-digit number according to the check table, and then arrange the English letters from left to right to get the plaintext.

It should be noted that unlike the uniqueness of the encryption process, since the number 24 can be decrypted into either I or J, the encryption process can produce different results. If the encryption mapping rule is regarded as a function, this encryption function does not have an inverse function. According to the task URL, it can be found by experiment: encrypt PROJECT once, and then decrypt the ciphertext, the result is PROIECT. Generally speaking, whether 24 is decrypted into I or J needs to be determined based on the context, which requires human work. For the algorithm to implement the encryption and decryption process of the Polybius Square Cipher, it is known from the experiment on the URL: 24 is always decrypted into I.
