Write an algorithm in pseudo code to find one element and delete it in a doubly linked list. Your algorithm will print the original list, request the user to put in an element to be deleted, then print the final list after the deletion is done. If the element doesn’t exist in the list, print "XXX is not in the list" where "XXX" should be the one you received from the user.

Use the following as your test cases to evaluate whether your algorithm works correctly:

if you have a linked list: 3<->2<->0,

with user input 5, your algorithm should print "5 is not in the list".

with user input 2, your algorithm should print  "3<->0".

if your linked list is empty, with user input 5, your algorithm should print "5 is not in the list".

II. Big Numbers 1. Implement this program in a file named bigNums.py. 2. Create a numerical (integer) list, named numbers. Populate the list with 1,000,000 (one million) integer values with values from 0 to 999,999. Hint: Use the range() function. 3. Print the length of the list to the screen. Ensure you have 1,000,000 items in your list. Hint: Use the len() function. 4. Print the smallest item value in the list to the screen. Hint: use the min() function. Example: print('List min value is: ' + str(min(numbers))) 5. Print the largest item value in the list to the screen. Hint: use the max() function. Example: print('List max value is: ' + str(max(numbers))) 6. Print the sum of all the item values to the screen. Hint: use the sum() function. Example: print('List sum is: ' + str(sum(numbers))) 7. Create a slice of the list starting at item index 100. 8. Make the slice 25 items in length. 9. Copy the slice to be a new list named new_numbers. 10. Print the new list to the screen.

Part 1

Here is some code:

def foo(var):

    var = []
    var.append("hello")
    var.append("world")

list = ["bah"]
foo(list)
print(list)

Which Option is correct?

A) ["hello","world"] is output because python passes the list by reference and the list is changed inside the function.

B) ["bah"] is output because python passes the list by value so changes to the list in the function are made to a separate list than the one that is passed in.

C) ["bah"] is output because python passes the list by reference but a new reference is created by the first line in the function so subsequent changes are made to a separate list than the one that is passed in.

Part 2

Consider this code:

list1 = []
list2 = list1

list2.append(1)
list2.append(2)
list1.append(3)

Which option is correct?

A) list1 contains [3] and list2 contains[1,2]

B) list1 contains [3] and list2 references the same list as list1

C) list1 contains [1,2,3] and list2 references the same list as list1

D) list2 contains [1,2,3] and list1 also contains [1,2,3] but the 3 is stored in a different location than list2

I need C++ programming with output. I have tried other programming and it does not work. So please give me the one that actually works.

Assignment 1

Design your own linked list class that works as a template class. It should provide member functions for appending, inserting and deleting nodes. The destructor should destroy the list. The class should also provide a member function that will display the contents of the list to the screen. The class should also provide a member function to search the list for an element in the list. The search should return the index (location) of the item in the list. So if it is the first element in the list then it should return 0. If the item is not in the list, it should return -1. Have main create two instances of the linked list with different data types and show that all of the functions work correctly.

Assignment 2

In this program you will use the linked list created in Assignment 1. First you will create a class that holds information about the weather for a given month which should be called WeatherStats. It should have data members that are doubles to hold the amount of rain for the month and the amount of snow for the month. It will also have a data member that holds the number of sunny days during the month. It should provide accessors and mutators for the private data members. Main will create an instance of the linked list with a data type of the WeatherStats (LinkedList). The program should ask the user for how many months they wish to enter weather statistics for. The program will then prompt the user for that information (rain, snow and sunny days). The data needs to be stored in the WeatherStats class and it should be appended to the linked list. Main must then call a function that displays the data in the list; this function will call the display function in the linked list. Main will call a function that determines the month with the largest and smallest amount of rain, snow and sunny days. This function should not be part of the linked list. It should appear in the same file as main. A function will need to be added to the linked list that provides an item from the list. The function in the linked list will return the object stored in the list. The function in main will need to request each item in the list one at a time. Another solution is to create a derived class of the linked list, which does all of the work for finding the largest and smallest.

The purpose for this project is to reinforce the knowledge from Chapter Two of the textbook. The students will practice how to implement stack and queue data structure using list structure, for instance, ArrayList. The students will also apply stack and queue in real project, for instance, to check if a string is a palindrom.

Tasks:

     1. Use ArrayList to implement MyStack class which define the data  

       structure that has Last In First Out property (35%)

     2. Use ArrayList to implement MyQueue class which define the data

       structure that has First In First Out property (35%)

     3. Write a function public static Boolean isPalindrome(String sentence)

       (30%). This function returns true if sentence is a palindrome; false   

       otherwise.

Students will use advanced looping methods including replicate(), lapply(), sapply(), and apply(), and access datasets provided with R packages in an R script.

1. The function call, rnorm(1), generates a normal random number. Use replicate() to generate 10 normal random numbers and assign them to a vector called nums.
   
2. The R statement, data(iris), loads the built-in R data set iris. This dataset has 150 rows and 5 columns. The 5 column names are "Sepal.Length","Sepal.Width","Petal.Length","Petal.Width" and "Species".
   1. Write R code(s) to return a list of 4 items that correspond to the averages of the first 4 columns in iris. The contents of the list should be as follows:
      
      $Sepal.Length
      [1] 5.843333
      
      $Sepal.Width
      [1] 3.057333
      
      $Petal.Length
      [1] 3.758
      
      $Petal.Width
      [1] 1.199333
      
3. With the iris dataset still loaded,
   1. write R code(s) to return a vector of 4 items that correspond to the averages of the first 4 columns in iris. The contents of the vector should be as follows:

4. The following R code converts the contents of the first 4 columns in iris to a matrix called data.
   data=as.matrix(iris[,1:4])
   1. Write R code(s) to use apply() to return a vector that contains the max values of the 4 columns. The contents of the vector should be as follows [Hint, use max()]:

5. Write R code(s) to read the contents of the provided file COS-206-ShoppingCart.html into a variable called cart and then show the first 5 lines of cart.

A. According to Equation 20.7, an ac voltage V is given as a function of time t by V = V_o sin 2ft, where V_o is the peak voltage and f is the frequency (in hertz). For a frequency of 56.0 Hz, what is the smallest value of the time at which the voltage equals one-half of the peak-value?

B. The rms current in a copy machine is 7.36 A, and the resistance of the machine is 19.8Ω. What are (a) the average power and (b) the peak power delivered to the machine?

C. A portable electric heater uses 21.8 A of current. The manufacturer recommends that an extension cord attached to the heater receive no more than 2.64 W of power per meter of length. What is the smallest radius of copper (resistivity 1.72 x 10^-8 Ω·m) wire that can be used in the extension cord? (Note: An extension cord contains two wires.)   of about 12A
