Not exactly "golfy", but it's more manageable than C. lmao
The form of input uses a `while` loop to take the array of numbers, simply `float`s, then the inputting stops if the input can't be converted into a `float`. Then takes another input for basing the calculation. And yes, I wrote the variable names as `n` and `x`.
