Hi, your job is to interpret a function f(x) that is implemented in the ./temp/function.py script. f(x) takes string inputs.
All you can do is call f(x) on an input string by running PYTHON(./temp/function.py string). 
Try to describe the function implemented by f(x) by running experiments on it. 
You can call the function on multiple inputs at a time by running PYTHON(./temp/function.py string1 string2 string3 ...). 
We encourage testing a large range of inputs before writing a description.
The goal is to find a good simple description of f(x) that explains most of the function behavior. f(x) may combine multiple different operations.
Your description of the function should be in the following form.
[DESCRIPTION]: Describe what the function is doing in language. 
[CODE]: Write python code that approximates the behavior of the function.

Alright, let's start by testing a few inputs to see the behavior of the f(x) function.

COMMAND: PYTHON(./temp/function.py "hello" "world" "test" "input")
user:
Response: Function input - output pairs: (hello, axJeeh) (world, phJkew) (test, mxJlm) (input, bgJinm) 

assistant:
Interesting! Let's try a few more test cases to better understand the behavior of the function.

COMMAND: PYTHON(./temp/function.py "AaBbCc" "123" "!@#")
user:
Response: Function input - output pairs: (AaBbCc, TtUJuVv) (123, 1J23) (!@#, !J@#) 

assistant:
Based on the input-output pairs, it looks like the function performs some mapping on the characters of the input string. Let's test a few more cases to understand the mappings.

COMMAND: PYTHON(./temp/function.py "abcde" "uvwxyz" "ABCDEFGHIJ")
user:
Response: Function input - output pairs: (abcde, tuJvwx) (uvwxyz, nopJqrs) (ABCDEFGHIJ, TUVWXJYZABC) 

assistant:
[DESCRIPTION]: The function appears to increment the first half of the input string by 20 positions in the alphabet (wrapping around if needed) and appends a "J" before processing the second half of the string. The second half of the string has its characters incremented by 1 position in the alphabet (wrapping around if needed).

[CODE]:
```python
def approx_function(s):
    mid = len(s) // 2
    first_half = [chr(((ord(c) - ord('a') + 20) % 26) + ord('a')) if c.islower() else chr(((ord(c) - ord('A') + 20) % 26) + ord('A')) for c in s[:mid]]
    second_half = [chr(((ord(c) - ord('a') + 1) % 26) + ord('a')) if c.islower() else chr(((ord(c) - ord('A') + 1) % 26) + ord('A')) for c in s[mid:]]
    return "".join(first_half) + "J" + "".join(second_half)
```
Please note that this approximation might not cover all edge cases, especially for numeric and special characters, but it seems to capture the general behavior of the provided examples.
