Let's Observe!

Let's examine the initial question below. This specific question involves the use of four (4) initial variables, namely: fs, input, firstName, and lastName. It's important to note that the variables fs and input are essential for the proper functioning of OpenClass coding questions, so there's no need to be concerned about these.

However, you may frequently encounter additional variables that are provided and hold significance for the question at hand. These variables will always be explicitly mentioned in the question prompt.
