<span>The technical relationship between inputs and outputs, which is needed to understand the difference between the short run and the long run, is called a production function.
Following are attached images that will help you understand the complete code. The code is tested with different variables and different outputs are obtained. All the necessary description is given in the form o comments inside the code.
