- Suppose we had support for multimethods instead of or in addition to overloading. Explain how you would implement the pretty printer of Project 1 using multimethods instead of having a print() method in each class of the hierarchy. What would be the advantage of using multimethods? You can simply use the same syntax as for overloading and indicate where the multimethod dispatch happens.Can you please create 2 files such that it will pass these 2 tests each: 1.

[Y] Yes [A] Yes to All [N] No [L] No to All [S] Suspend [?] Help (default is "Y"):Task 3: Measure the Entropy of Kernel In the virtual world, it is difficult to create randomness, i.e., software alone is hard to create random numbers. Most systems resort to the physical world to gain the randomness. Linux gains the randomness from the following physical resources: void add_keyboard_randomness(unsigned char scancode); void add_mouse_randomness(__u32 mouse_data); void add_interrupt_randomness(int irq); void add_blkdev_randomness(int major); The first two are quite straightforward to understand: the first one uses the timing between key presses; the second one uses mouse movement and interrupt timing; the third one gathers random numbers using the interrupt timing. Of course, not all interrupts are good sources of randomness. For example, the timer interrupt is not a good choice, because it is predictable. However, disk interrupts are a better measure. The last one measures the finishing time of block device requests. The randomness is measured using entropy, which is…
