The question is attached below

• Research cases of illegal wiretapping within the United States.
• Evaluate why a given instance of wiretapping was illegal.

Create a Python dictionary that returns a list of values for each key. The key can be whatever type you want. 

Design the dictionary so that it could be useful for something meaningful to you. Create at least three different items in it. Invent the dictionary yourself. Do not copy the design or items from some other source. 

Next consider the invert_dict function from Section 11.5 of your textbook. 

# From Section 11.5 of: 
# Downey, A. (2015). Think Python: How to think like a computer scientist. Needham, Massachusetts: Green Tree Press. 

def invert_dict(d):
     inverse = dict()
     for key in d:
          val = d[key]           if val not in inverse:
               inverse[val] = [key]           else:
               inverse[val].append(key)
     return inverse 

Modify this function so that it can invert your dictionary. In particular, the function will need to turn each of the list items into separate keys in the inverted dictionary. 

Run your modified invert_dict function on your dictionary. Print the original dictionary and the inverted one. 

Include your Python program and the output in your Learning Journal submission. 

Describe what is useful about your dictionary. Then describe whether the inverted dictionary is useful or meaningful, and why. 

PART 2 

Describe how tuples can be useful with loops over lists and dictionaries, and give Python code examples. Create your own code examples. Do not copy them from the textbook or any other source. 

Your descriptions and examples should include the following: the zip function, the enumerate function, and the items method. 

Question 1: Using stack to implement queue. (You can define your own stack class, or use the Stack class in Java API)

Question 2: Using queue to implement stack. (You can define your own queue class, or use the Queue class in Java API)

Demo them in a test program

Requirements: Submit the repl.it links of the two programs

Please note that you need to submit two repl.it links. You can copy and paste the two links in a .txt/.docx file and upload the file. You can also submit the second link as comments in the assignment submission.

Please respond to the following discussion response with a minimum of 200 words and use a reference. 

ArrayList:

Characteristics:

• ArrayList is used to store components and remove components at any  time because it is flexible to add and remove the components.  
• ArrayList is similar to arrays but the arrays were deterministic and ArrayList was non-deterministic.
• ArrayList allows adding duplicate components.
• ArrayList maintains the order of components in the order of insertion.

The following statement shows how to initialize the ArrayList.

ArrayList list=new ArrayList();

The above list object is used to add different types of components into ArrayList.

ArrayList list=new ArrayList();

The above list object is used to add only the String type component  into the ArrayList. If someone tries to add other types of components  then it provides a compile-time error.

The following statement shows how to add components into ArrayList.

list.add("Cat");

list.add("Dog");

list.add("Cow");

list.add("Horse");

add() is the method used to add components into the ArrayList. Here  the String type is specified so the parameters are enclosed with the  double-quotes. Instead of String Integer type is provided then the  number is passed as a parameter without double-quotes.

The following statement shows how to update components in ArrayList.

list.set(1,"Goat");

Now the component at index 1 is set as Goat instead of Dog. In the  set() method the first parameter specifies the index value and the  second parameter specifies the updated component.

The following statements show how to get all the components that were stored in the ArrayList.

for(String str: list)

{

System.out.println(str);

}

From the above statement, the for-each loop is used to iterate the ArrayList to get all the components in the ArrayList.

Iterator it=list.iterator();

while(it.hasNext())

{

System.out.println(it.next());

}

From the above statement, the Iterator interface is used to get the ArrayList components.

The following statement shows how to remove components from the ArrayList.

list.remove(0);

Now the component at index 0 is deleted from the ArrayList.

The following is the java code that implements the ArrayList.

import java.util.*;

public class ArrayListDataStructure 

{

public static void main(String[] args)

{

ArrayList list=new ArrayList();

list.add("Cat");

list.add("Parrot");

list.add("Horse");

list.add("Cow");

list.add("Dog");

System.out.println("ArrayList Components");

for(String str:list)

{

System.out.println(str);

}

list.set(2, "Golden Fish");

System.out.println("nArrayList Components after update");

for(String st:list)

{

System.out.println(st);

}

System.out.println("Size of ArrayList:"+list.size());

list.remove(3);

System.out.println("nArrayList Components after Delete");

for(String str:list)

{

System.out.println(str);

}

System.out.println("Size of ArrayList:"+list.size());

list.add("Love Birds");

Collections.sort(list);

System.out.println("nArrayList Components after Sorting");

for(String str:list)

{

System.out.println(str);

}

}

}

LinkedList:

• Characteristics of LinkedList are the same as ArrayList like  allowing duplicate components, components stored in the order of  insertion, and non synchronized.
• The difference is that manipulation is fast in LinkedList as  compared to ArrayList because the ArrayList needs more shifting to  remove a component but the LinkedList does not need shifting.

The following statement shows how to initialize the LinkedList.

LinkedList ll=new LinkedList();

The following statement shows how to add components into LinkedList.

ll.add("James");

ll.add("Daniel");

ll.addFirst("Hepson");

ll.addLast("Shibi");

The following statement shows how to update components in LinkedList.

ll.set(2,"Anisha");

The following statements show how to get all the components that were stored in the LinkedList.

for(String st:ll)

{

System.out.println(st);

}

The following statement shows how to remove components from LinkedList.

ll.remove(3);

The following is the java code that implements LinkedList.

import java.util.Collections;

import java.util.LinkedList;

public class LinkedListDataStructure 

{

public static void main(String[] args)

{

LinkedList ll=new LinkedList();

ll.add("Dhanya");

ll.add("Daniel");

ll.add("Xavier");

ll.addFirst("Hepson");

ll.addLast("Shibi");

System.out.println("LinkedList Components");

for(String st:ll)

{

System.out.println(st);

}

ll.set(2,"Anisha");

System.out.println("nLinkedList Components after update");

for(String st:ll)

{

System.out.println(st);

}

System.out.println("Size of LinkedList:"+ll.size());

ll.remove(3);

System.out.println("nLinkedList Components after Delete");

for(String st:ll)

{

System.out.println(st);

}

System.out.println("Size of LinkedList:"+ll.size());

Collections.sort(ll);

System.out.println("nLinkedList Components after Sorting");

for(String st:ll)

{

System.out.println(st);

}

}

}

Vector:

• Vector is also a dynamic array so there is no size limit.
• Vector class implements List interface so all the methods in List interface can be used in Vector.
• Vector is synchronized so it is better to use vector in thread-safe implementation.

The following statement shows how to initialize a Vector class.

Vector vec=new Vector();

The following statement shows how to add components to a Vector.

v.addElement("Cake");

v.addElement("Biscuit");

v.addElement("IceCream");

v.addElement("Chocolate");

The following statement shows how to update components in Vector.

v.set(1,"Drinks");

The following statement shows how to remove components from the Vector.

v.remove(3);

The following is the java code that implements Vector.

import java.util.Collections;

import java.util.Vector;

public class VectorDataStructure 

{

public static void main(String[] args)

{

Vector v =new Vector(); 

v.addElement("Cake");

v.addElement("Biscuit");

v.addElement("IceCream");

v.addElement("Chocolate");

System.out.println("Vector Components");

for(String st:v)

{

System.out.println(st);

}

v.set(1,"Drinks");

System.out.println("nVector Components after update");

for(String st:v)

{

System.out.println(st);

}

System.out.println("Size of Vector:"+v.size());

v.remove(3);

System.out.println("nVector Components after Delete");

for(String st:v)

{

System.out.println(st);

}

System.out.println("Size of Vector:"+v.size());

v.add("Biscuit");

Collections.sort(v);

System.out.println("nVector Components after Sorting");

for(String st:v)

{

System.out.println(st);

}

}

}

ArrayList:

The ArrayList is a resizable array that can be used to store  different types of components at any time. In ArrayList components can  be added anywhere by specifying the index.

The following is the description of the code

• Initialize an ArrayList class.
• Use add() method to add components into the ArrayList class.
• For-each loop is used to print the components.
• Use the set() method to update the component.
• Use the remove() method to delete the component.
• Use size() to get the current size of the ArrayList.
• Use the sort() method in Collections to sort the components in the ArrayList.

LinkedList:

LinkedList class is used to implement the Linked List linear data  structure. The components are not stored in the neighboring address and  it is stored as containers.  

The following is the description of the code.

• Initialize the LinkedList class.
• Use add() method to add components into the LinkedList class.
• For-each loop is used to print the components.
• Use the set() method to update the component.
• Use the remove() method to delete the component.
• Use size() to get the current size of the LinkedList.
• Use the sort() method in Collections to sort the components in the LinkedList.

Snip of the Output:

Vector:

Vector is the growable array. Vector is synchronized so it has legacy  methods. Iterators can not be returned by the vector class because if  any concurrent changes occur then it throws the  ConcurrentModificationException.

The following is the description of the code

• Initialize the Vector class.
• Use and elements() method to add components into the Vector class.
• For-each loop is used to print the components.
• Use the set() method to update the component.
• Use the remove() method to delete the component.
• Use size() to get the current size of the Vector.
• Use the sort() method in Collections to sort the components in the Vector.

1. A local copy center needs to buy white paper and yellow paper. They can buy from three suppliers. Supplier 1 sells a package of 20 reams of white and 10 reams of yellow for $60. Supplier 2 sells a package of 10 reams of white and 10 reams of yellow for $40. Supplier 3 sells a package of 10 reams of white and 20 reams of yellow for $50. The copy center needs 350 reams of white and 400 reams of yellow. Using Python, determine (1) how many packages they should buy from each supplier in order to minimize cost and (2) the minimum cost.

2. A new test has been developed to detect a particular type of cancer. A medical researcher selects a random sample of 1,000 adults and finds (by other means) that 4% have this type of cancer. Each of the 1,000 adults is given the new test and it is found that the test indicates cancer in 99% of those who have it and in 1% of those who do not. Based on these results, what is the probability of a randomly chosen person having cancer given that the test indicates cancer? What is the probability of a person having cancer given that the test does not indicate cancer?Round the probabilities to four decimal places.

3. If a tank holds 5000 gallons of water, which drains from the bottom of the tank in 40 minutes, then the volume of the water remaining in the tank after minutes is given by . Using Python, determine the rate at which water is draining from the tank. When will it be draining the fastest?

4. A rectangular container with a volume of 475 ft3 is to be constructed with a square base and top. The cost per square foot for the bottom is $0.20, for the top is $0.10, and for the sides is $0.015. Find the dimensions of the container that minimize the cost. Round to two decimal places.

5. Assume the total revenue from the sale of items is given by while the total cost to produce items is . Find the approximate number of items that should be manufactured so that profit is maximized. Justify that the number of items you found gives you the maximum and state what the maximum profit is.

6. For the following function, determine the domain, critical points, intervals where the function is increasing or decreasing, inflection points, intervals of concavity, intercepts, and asymptotes where applicable. Use this information and Python to graph the function.

Domain:

By inspection, the value x = -2 will cause the denominator to be equal to 0. Thus the value x = -2 must be excluded from the domain. There are no other values that must be excluded, thus the domain is (-∞, -2) U (-2, ∞).

7. The rate of growth of the profit (in millions) from an invention is approximated by the function where represents time measured in years. The total profit in year two that the invention is in operation is $25,000. Find the total profit function. Round to three decimals.

8. For a certain drug, the rate of reaction in appropriate units is given by

9. Determine if the following function is a probability density function on . 

10. Researchers have shown that the number of successive dry days that occur after a rainstorm for a particular region is a random variable that is distributed exponentially with a mean of 9 days. Using Python, determine the (separate) probabilities that 13 or more successive dry days occur after a rainstorm, and fewer than 2 dry days occur after a rainstorm. Round the probabilities to four decimal places.

Final Note:I know that many of you are thinking “I have no experience with construction, building decks, landscaping, etc…”  What you must realize is that when you seek employment as a project manager, you will always have this conundrum of wondering how much you really need to know about the area of work the project lies within (telecom, healthcare, IT, travel, constructions, finance, insurance etc…) to be an effective, successful project manager.   Some employers will place great importance on the amount of knowledge you have in a particular area, others like myself, will not.  What you must be ready to do is learn/absorb as much knowledge in the area of project work as soon as possible.  Be ready to explore all your options to gain and find the knowledge you need to function effectively.  You need enough vocabulary and understanding to operate and communicate well.
