In a computer system, memory operations currently take up 30% of execution time. A new gadget called a cache (i. e. an L1 cache) speeds-up 80% of the memory operations by a factor of 4. (a) [2] What is the speed-up due to the cache? (b) [3] A second new gadget called an L2 cache speeds-up half the remaining 20% of the memory operations by a factor of 2. What is the total speed-up with the L1 and L2 cache together? Note: It is useful to draw pictures to solve this part of the problem

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.
