Print numbers 0, 1,2,., userNum as shown, with each number indented by that number of spaces. For each printed line, print the leading spaces, then the number, and then a newline. Hint: Use i and j as loop variables (initialize i and j explicitly). Note: Avoid any other spaces like spaces after the printed number. Ex: userNum = 3 prints: %3D 1 2. 3

The data attribute of the LinkNode should be a reference/pointer of the Currency class of Lab 2. Do not make it an inner class or member structure to the SinglyLinkedList class of #2 below. A SinglyLinkedList class which will be composed of three attributes - a count attribute, a LinkNode pointer/reference attribute named as and pointing to the start of the list and a LinkNode pointer/reference attribute named as and pointing to the end of the list.

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…
Imagine a conversation between parts of your email program. P1: Hey P2! The user clicked delete!P2: Yes. That is a valid choice at this time. Hey, P3, can you delete this email. P3: Just a moment!... It’s deleted. Here is the list of available messages. Anything else?P2: Nope. P1, here is the new list of messages.P1: Thanks P2. I have displayed the new list.In this example: Group of answer choices 1. P3 is the controller, P1 is the view, P2 is the model. 2. P1 is the controller, P3 is the model, P2 is the view. 3. None of these are true. 4. P2 is the controller, P1 is the view, P3 is the model.
