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 calling the function with a few different input strings.

COMMAND: PYTHON(./temp/function.py "hello" "world" "test" "input")
user:
Response: Function input - output pairs: (hello, hNllNyNNh) (world, wNrldyNNh) (test, tNstyNNh) (input, NnpNtyNNh) 

assistant:
Interesting. Let's try some more inputs, including some with special characters, numbers, and uppercase letters.
COMMAND: PYTHON(./temp/function.py "123" "ABC" "!@#" "HeLlO" "woRd123")
user:
Response: Function input - output pairs: (123, 123yNNh) (ABC, NBCyNNh) (!@#, !@#yNNh) (HeLlO, HNLlNyNNh) (woRd123, wNRd123yNNh) 

assistant:
Based on the inputs and outputs so far, it seems that the function is processing each character in some specific way (sometimes altering the character or position), and then appending 'yNNh' at the end of the output string. Let's try a few more examples.

COMMAND: PYTHON(./temp/function.py "HelloWorld" "example" "MixedUpperCase" "special_characters!@#")
user:
Response: Function input - output pairs: (HelloWorld, HNllNWNrldyNNh) (example, NxNmplNyNNh) (MixedUpperCase, MNxNdNppNrCNsNyNNh) (special_characters!@#, spNcNNl_chNrNctNrs!@#yNNh) 

assistant:
[DESCRIPTION]: The function appears to process each character in the input string with the following rules:
1. If the character is a lowercase 'e', change it to 'N'
2. If the character is an uppercase 'B', change it to 'N'
3. If the character is a lowercase 'o', change it to 'N'
4. If the character is an uppercase 'C', change it to 'N'
5. If the character is a lowercase 'a', change it to 'N'

The function then appends 'yNNh' at the end of the transformed string.

[CODE]:
```python
def approximate_function(input_string):
    output_string = ""
    for char in input_string:
        if char == 'e':
            output_string += 'N'
        elif char == 'B':
            output_string += 'N'
        elif char == 'o':
            output_string += 'N'
        elif char == 'C':
            output_string += 'N'
        elif char == 'a':
            output_string += 'N'
        else:
            output_string += char
    return output_string + 'yNNh'
```

Please note that this approximation might not cover all cases, but the provided inputs and outputs lead to these observations.
