Function not returning value due to errors in if else logic

I hope this helps . Your remove_slash is recursive, and your recursion calls return nothing. So somewhere down the recursion stack, the correct string is returned, but the next level up does not return anything, so None is the actual return. Just add a return in your else block:
def remove_slash(path):
    print(f"Entering with : {path}")
    if path[-1].isalnum():
        print(f"iffffff {path[-1].isalnum()}::::{path[-1]} ::: {path}")
        return path   # **THIS NEVER GETS RETURNED**
    else:
        print(f"else : {path}")
        return remove_slash(path[:len(path)-1])

will be helpful for those in need In PHP variable names begin with a $ dollar sign.
You should have written $str instead of str:
function h($str) { echo htmlspecialchars($str); }

using fmod in a function, loop logic is returning unexpected value

around this issue Your problem is, that the logic behind function calculateCoins(float change) is wrong.
You first initialize result with a value of 1. In your loop, you check against result > 0.
float calculateCoins(float change)
{
    int x=1;
    float result=1;

    while (change - x*0.25 > 0)
    {
        x++;
    }

    return x;
}

Unable to customize form errors because server is returning 422 Unprocessable Entity without returning errors

With these it helps Laravel returns the HTTP 422 - Unprocessable Entity when the validations you set fail. In your case I would take a closer look at the data you're posting to the server and manually check if it passes the validation cases you wrote.
To get the exact fields that are causing the error you need to handle this in your code, like this for example:
$validator = Validator::make($data, $rules);

if ($validator->fails()) {

  // 500 is the HTTP Status Code you want to return.   
  // This should also throw you in the catch branch of your front-end code
  return response()->json(['errors'=>$validator->errors()], 500);

}

Including <d3dkmthk.h> causes errors 'E0090 function returning function is not allowed'

To fix this issue The problem was caused by #define WIN32_LEAN_AND_MEAN, deleting this line solved the issue.
