This portion of the code creates the variables and initializes them with the test values. This is just one
set of test variables. Because this is not being implemented as a function, it is not possible to run
multiple tests on the code in a single document. Therefore, to ensure that the code is correct, the code
should be executed several times with different values in the test variables.
