Part A - Palindromic Bitlists Write a function palindrome binary(n) which returns a list of bitlists of length n, where every bitlist is a palindrome. The returned list of bitlists must be in lexicographical order (think about the order of your options). You must use backtracking to solve this problem (i.e. do not use brute force).
Part B - All Paths Write a function all paths(M, u, v) which takes as input an adjacency matrix of a graph, M, and two vertices u, v and returns a list of all paths from u to v in M. A path is a list of vertices. Note that a path cannot use the same vertex twice, but two different paths can use some of the same vertices. The returned list of paths must be in lexicographical order. You must use backtracking to solve this problem (i.e. do not use brute force).

1. Star with Newton's third law: dp/dt = ΣF where p is the momentum. In space, the sum of the external forces ΣF = 0. For a rocket in space, the mass and velocity change with time as the rocket expends its fuel. Show from Newton's third law that ΔV = v ln(m/M) where m is the initial mass of the rocket, M is the final mass of the rocket after the fuel is expended, v is the rocket's exhaust velocity and ΔV is the change in the velocity for the rocket
2. Now, the rocket needs to get to escape velocity to get to the moon. Use conservation of energy to derive an expression for the escape velocity. If we start at 200km above the surface of earth, calculate the ΔV we need to escape from Earth and get to the moon.
3. Finally, use the earlier Rocket Equation calculate the fraction of the initial rocket's mass that is dedicated to fuel to make the journey from the Earth to the Moon. In this case, v is 4500 m/s.

Note: This problem is for the 2018 tax year.
Lance H. and Wanda B. Dean are married and live at 431 Yucca Drive, Santa Fe, NM 87501. Lance works for the convention bureau of the local Chamber of Commerce, while Wanda is employed part-time as a paralegal for a law firm.
During 2018, the Deans had the following receipts:
|
Wanda was previously married to John Allen. When they divorced several years ago, Wanda was awarded custody of their two children, Penny and Kyle. (Note: Wanda has never issued a Form 8332 waiver.) Under the divorce decree, John was obligated to pay alimony and child support—the alimony payments were to terminate if Wanda remarried.
In July, while going to lunch in downtown Santa Fe, Wanda was injured by a tour bus. As the driver was clearly at fault, the owner of the bus, Roadrunner Touring Company, paid her medical expenses (including a one-week stay in a hospital). To avoid a lawsuit, Roadrunner also transferred $90,000 to her in settlement of the personal injuries she sustained.
The Deans had the following expenditures for 2018:
|
The life insurance policy was taken out by Lance several years ago and designates Wanda as the beneficiary. As a part-time employee, Wanda is excluded from coverage under her employer's pension plan. Consequently, she provides for her own retirement with a traditional IRA obtained at a local trust company. Because the mayor is a member of the local Chamber of Commerce, Lance felt compelled to make the political contribution.
The Deans' household includes the following, for whom they provide more than half of the support:
|
Penny graduated from high school on May 9, 2018, and is undecided about college. During 2018, she earned $8,500 (placed in a savings account) playing a harp in the lobby of a local hotel. Wayne is Wanda's widower father who died on January 20, 2018. For the past few years, Wayne qualified as a dependent of the Deans.
Federal income tax withheld is $5,200 (Lance) and $2,100 (Wanda). The proper amount of Social Security and Medicare tax was withheld.
Required:
Determine the Federal income tax for 2018 for the Deans on a joint return by providing the following information that would appear on Form 1040 and Schedule A. They do not want to contribute to the Presidential Election Campaign Fund. All members of the family had health care coverage for all of 2018. If an overpayment results, it is to be refunded to them.

Modify the program #1 to allow the user to enter name-score pairs. For each student taking a test, the user types a string representing the name of the student, followed by an integer representing the student's score. (use a structure) Modify the average-calculating function so they take arrays of structures, with each structure containing the name and score of a single student. In traversing the arrays, use pointers notation rather than array indices. (myArray->name or *(myArray).name) Make it a class. You will need a destructor because you are using dynamic arrays.
I need your help! This is fundamental II. Thank you

Objectives
Tasks
This assignment has two parts:
Task 1 – File Input
The first piece of information we need is a text file’s name and location. Ask the user through the console what the file’s name and location are. After that, please ensure that the file does exist and at the given location. If the file does not exist or cannot be read, please return a message to the user stating that and ask them to enter another name and location.
Finally, if the file can be read then simply copy/read every line from the file. The contents of this file will be used in the next task.
Task 2 – File Output
Ask the user, through the console, what the name of the copy of the previous file should be called and where it should be saved. Check to see if a file with the same name already exists at the location given and if one does ask the user if they want to overwrite the file that already exists or if they would like to change the name and location of the new file. If they wish to change the name and location, go through the process of getting their input again through the console and checking if the newly given name and location are taken already too.
If they want to overwrite or no file already exists in the given location with the given name, then place the copied contents of the file that was read in the first task into this new file.
After successfully copying the contents of the first file into the second file, print to the console the name and location of both of those files.
A sample text file named “textfile.txt” has been supplied in case you need a file to test the above code on. The contents of that file is the declaration of independence.
∃ Some Sample Output:
Please enter a text file name and location:
C:\Users\source\repos\1322L_Assignment6\bin\Debug\textfiladsfe.txt22
This file does not exist!
Please enter a text file name and location:
C:\Users\source\repos\1322L_Assignment6\bin\Debug\textfile.txt
Please enter a new file name and location:
C:\Users\source\repos\1322L_Assignment6\bin\Debug\DeclarationOfIndependence.txt
A file already exists with that name!
Would you like to overwrite it or enter a different name? (0 or 1) 0
The file will be overwritten.
The file “C:\Users\source\repos\1322L_Assignment6\bin\Debug\textfile.txt” has been copied to “C:\Users\source\repos\1322L_Assignment6\bin\Debug\DeclarationOfIndependence.txt”.
