Write a function 'sort_list()' that accepts a list of integers and sorts it. The function should not explicitly 'return' this list and yet the list will be sorted when printed within main() after being passed to sort_list() as a parameter. Complete the main() module such that it accepts numbers from the user, until an empty string is entered, and stores them in a list called 'a_list'. Input: 2 32 43 12 24 32 Output: [2, 32, 43, 12, 24, 32] [2, 12, 24, 32, 32, 43] Hint: Functions have the ability to modify mutable objects in the calling program. A 'list' is a mutable object. Read section 8.1.2 in the book.

Write a car class having two private member variables called tank and speed. write public methods called pumpgas and gofast. the method pumpgas gets an integer for gas that must be pumped. that value needs to be added to tank (no more than 20 gallons). it must return the amount of gas that is purchased ($4 per gallon). the method gofast should increase the speed by 5 each time it is called. write a constructor for the above class that initialized both variables to zero. write a tostring to display both the tank and speed when the car is printed. modify the car class to implement the interface comparable and an interface called carinter having the public methods in carinter. write the main program to create an array of size 5 of type car. create 5 car objects having each location of the array to refer to one of the cars. test the pumpgas, gofast, equals method on the array items. write an enhanced loop to print all the car values (using a tostring written last time).write a generic method to find the minimum of four items. pass int, double, char, string and car objects to test this method.
