First, we must define the functions we will be using. We know that we need to calculate the maximum, minimum, range, and mean, so you should write functions for each of these calculations. We also need to include a function that checks if the vectors are in ascending order. Keep in mind that we want all of these to return an int exxept for the last one, which should return a bool.
