Shindler gives lots of homework assignments, each of which have an easy version and a hard version1. Each student is allowed, for each homework, to submit either their answer to the easy version (and get ei > 0 points) or the hard version (and get hi > 0 points, which is also guaranteed to always be more than ei) or to submit neither (and get 0 points for the assignment). Note that ei might have different values for each i, as might hi. The values for all n assignments are known at the start of the semester.
The catch is that the hard version is, perhaps not surprisingly, more difficult than the easy version. In order for you to do the hard version, you must have not done the previous assign- ment at all: neither the easy nor the hard version (and thus are more relaxed, de-stressed, etc). Your goal is to maximize the number of points you get from homework assignments over the course of the semester. Give an efficient dynamic programming algorithm to determine the largest number of points possible for a given semester’s homework choices.

In Python 3:
Software Design Patterns may be thought of as blue prints or recipes for implementing common models in software. Much like re-using proven classes in Object Oriented design, re-using proven patterns tends to produce more secure and reliable results often in reduced time compared to re-inventing the wheel. In fact, some high-level languages have integrated facilities to support many common patterns with only minimal, if any, user written software. That said, in software design and construction, often the challenge is to know that a pattern exists and be able to recognize when it is a good fit for a project. To give you a familiar frame of reference, below is a Singleton Pattern implemented in Java:
public class MySingleton {
// reference to class instance
private static MySingleton instance = null;
// Private Constructor
private MySingleton() {
instance = this;
}
// Returns single instance to class
public static MySingleton getInstance() {
if (instance == null) {
instance = new MySingleton();
}
return instance;
}
public static void main(String[] args)
{
MySingleton s1 = MySingleton.getInstance();
MySingleton s2 = MySingleton.getInstance();
System.out.println("s1: " + s1 + " s2: " + s2);
}
}
If you run this example, you will see that the address for s1 and s2 are exactly the same. That is because the pattern restricts the existence of more than one instance in a process. Of course this example only implements the pattern but other functionality can be added to this class just as any other class. The primary features of a singleton are:
The primary goal of this assignment is not to teach you how to write singleton patterns in Python, (though that’s part of it), but to familiarize you with the concept of design patterns as well as give you experience in adapting one into one of your own designs.
Description
Pick one of your previous assignments, either from MindTap or one of your Distributed Systems assignments and integrate a Singleton Pattern into it. Hint: Any class can be made into a Singleton.

This is Mr. Burns. Mr. Burns is an 88-year-old male who had an emergent partial gastrectomy today because of a perforated ulcer. Mr. Burns has a history of CHF, hypertension, and he takes warfarin for atrial fibrillation. Because of the perforation, Mr. Burns lost quite a bit of blood prior to surgery, so he received 3 units of packed red blood cells in addition to 2 units of fresh frozen plasma for an elevated INR (it was 5 prior to surgery now it is 1.6). He also received 2 Liters of lactated ringers in the OR. He has a large abdominal incision with a cover dressing intact. There is some bloody drainage present on the dressing, which has been marked. He has an NG tube in the left nare to low intermittent suction. There is a small amount of dark drainage noted in the collection container. There is a central line present in the left neck that was placed by anesthesiology during surgery. He has an indwelling urinary catheter that is draining clear yellow urine. He reports incisional pain 5/10 and states this is tolerable. He is drowsy, but arousable and answers questions appropriately. He's received a total of 0.5 mg hydromorphone while int the PACU. VS are as follows: BP 110/84, HR 96, RR 16, SPO2 98% 2L/NC, T 98.6 F
