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. 
assistant:
COMMAND: PYTHON(./temp/function.py "hello" "world" "test" "12345")
user:
Response: Function input - output pairs: (hello, Hello) (world, World) (test, Test) (12345, 12345) 

assistant:
Let's test some more inputs to see if a pattern emerges.

COMMAND: PYTHON(./temp/function.py "a" "apple" "Example" "Rhino" "ELEPHANT" "mIxEdCaSe")
user:
Response: Function input - output pairs: (a, A) (apple, Apple) (Example, Examule) (Rhino, Rhino) (ELEPHANT, Elepmant) (mIxEdCaSe, Mixeicase) 

assistant:
Based on the input-output pairs, it seems like the function is capitalizing the first character of the input string and performing some operation on the other characters. Let's test some more inputs to get a clearer understanding.

COMMAND: PYTHON(./temp/function.py "house" "car" "Nation" "builder" "running" "Computer")
user:
Response: Function input - output pairs: (house, House) (car, Car) (Nation, Natitn) (builder, Builier) (running, Runnnng) (Computer, Compzter) 

assistant:
[DESCRIPTION]: The function capitalizes the first character of the input string and, for all uppercase alphabetical characters in the original string, swaps them with the previous character in the modified string.

[CODE]: 
```
def approximate_function(s: str) -> str:
    if not s:
        return s
    modified_string = list(s.capitalize())
    for i in range(1, len(modified_string)):
        if s[i-1].isupper():
            modified_string[i-1], modified_string[i] = modified_string[i], modified_string[i-1]
    return ''.join(modified_string)
```
