This program exercise #4 wants the user to write a program in python that contains a list of movies titles, years and movie rating. You will need to display a menu option that allows the user to list all of the movies, add a movie, delete a movie and exit out of the program. This will be done using lists and the functions to add an element to a list and how to delete an element to a list. The program should be written utilizing functions in python for the main function, the display_menu function, the delete function, the add function and the list movie function. You can place this all in one python file or include them in various python files that include them into the main program. Let me know if you have any questions with this exercise. Output Screen: COMMAND MENU list - List all movies add - Add a movie del - Delete a movie exit - Exit program Command List: list 1. Monty Python and the Holy Grail, 1979, R 2. On the Waterfront, 1954, PG 3. Cat on a Hot Tim Roof, 1958, R Command: add Name: Gone with the Wind Year: 1939 Rating: PG Gone with the Wind was added.

Answer:

The program in Python is as follows:

def display_menu(titles,years,ratings):

   for i in range(len(titles)):

       print(str(i+1)+". "+titles[i]+", "+str(years[i])+", "+str(ratings[i]))

def delete(titles,years,ratings):

   del_item = input("Movie: ")

   if del_item in titles:

       print(del_item,"was deleted")

       index = titles.index(del_item)

       titles.pop(index)

       years.pop(index)

       ratings.pop(index)

   return(titles,years,ratings)

def add(titles,years,ratings):

   title = input("Title: ")

   year = int(input("Year: "))

   rating = int(input("Ratings: "))

   print(title,"was added")

   titles.append(title)

   years.append(year)

   ratings.append(rating)

   return(titles,years,ratings)

titles = []

years = []

ratings = []

print("COMMAND MENU list\nlist - List movies\nadd - Add movie del\ndel - Delete movie exit\nexit - Exit program")

menu = (input("Command List: "))

while(menu.lower() == "list" or menu.lower() == "add" or menu.lower() == "del"):

   if menu.lower() == "list":

       display_menu(titles,years,ratings)

   elif menu.lower() == "add":

       titles, years, ratings = add(titles,years,ratings)

   elif menu.lower() == "del":

       titles, years, ratings = delete(titles,years,ratings)

   menu = (input("Command List: "))

   elif menu.lower() == "exit":

       break

print("Exited!!!")

Write a program that lets the user perform arithmetic operations on fractions. Fractions are of the form a/b, in which a and b are integers and b is not equal to 0. Your program must be menu driven, allowing the user to select the operation ( , -, *, or /) and input the numerator and the denominator of each fraction. Furthermore, your program must consist of at least the following function

menu: This function informs the user about the program's purpose, explains how to enter data, how to quit and allows the user to select the operation.
addFractions: This function takes as input four integers representing the numerators and denominators of two fractions, adds the fractions, and returns the numerator and denominator of the result.
subtractFractions: This function takes as input four integers representing the numerators and denominators of two fractions, subtracts the fractions, and returns the numerator and denominator of the result.
multiplyFractions: This function takes as input four integers representing the numerators and denominators of two fractions, multiplies the fractions, and returns the numerator and denominator of the result.
divideFractions: This function takes as input four integers representing the numerators and denominators of two fractions, divides the fractions, and returns the numerator and denominator of the result.

Your company has a benchmark that is considered representative of your typical applications. One of the older-model workstations does not have a floating-point unit and must emulate each floating-point instruction by a sequence of integer instructions. This older-model workstation is rated at 120 MIPS on this benchmark. A 3rd -party vendor offers an attached processor that is intended to give a hardware accelerator to your workstation. The attached processor executes each floating-point instruction on a dedicated processor, without emulation. The workstation/attached processor rates 80 MIPS on the same benchmark. The following symbols are used to answer this exercise:

I – Number of integer instructions executed on the benchmark
F – Number of floating-point instructions executed on the benchmark
Y – Number of integer instructions to emulate a float-point instruction
W – Time to execute the benchmark on the processor alone
B – Time to execute the benchmark on the processor/coprocessor combination.

Required:
a. Write an equation for the MIPS rating of each configuration using the symbols above.
b. What is the value of B?
c. What is the MFLOPS rating of the system with the coprocessor?
d. Your colleague wants to purchase the coprocessor even though the MIPS rating for the configuration using the coprocessor is less than that of the processor alone. Is your colleague’s evaluation correct?

Write a method maxMagnitude() with two integer input parameters that returns the largest magnitude value. Use the method in a program that takes two integer inputs, and outputs the largest magnitude value.

Ex: If the inputs are: 5 7 the method returns: 7
Ex: If the inputs are: -8 -2 the method returns: -8

Write a MIPS assembly language program that prompts for a user to enter a series of floating point numbers and calls read_float to read in numbers and store them in an array only if the same number is not stored in the array yet. Then the program should display the array content on the console window.
Consult the green sheet and the chapter 3 for assembly instructions for floating point numbers. Here is one instruction that you might use:
c.eq.s $f2, $f4
bc1t Label1
Here if the value in the register $f2 is equals to the value in $f4, it jumps to the Label1. If it should jump when the value in the register $f2 is NOT equals to the value in $f4, then it should be:
c.eq.s $f2, $f4
bc1f Label1
To load a single precision floating point number (instead of lw for an integer), you might use:
l.s $f12, 0($t0)
To store a single precision floating point number (instead of sw for an integer), you might use:
s.s $f12, 0($t0)
To assign a constant floating point number (instead of li for an integer), you might use:
li.s $f12, 123.45
To copy a floating point number from one register to another (instead of move for an integer), you might use:
mov.s $f10, $f12
The following shows the syscall numbers needed for this assignment.
System Call System Call System Call
Number Operation Description
2 print_float $v0 = 2, $f12 = float number to be printed
4 print_string $v0 = 4, $a0 = address of beginning of ASCIIZ string
6 read_float $v0 = 6; user types a float number at keyboard; value is store in $f0
8 read_string $v0 = 8; user types string at keybd; addr of beginning of string is store in $a0; len in $a1
------------------------------------------
C program will ask a user to enter numbers and store them in an array
only if the same number is not in the array yet.
Then it prints out the result array content.
You need to write MIPS assembly code based on the following C code.
-------------------------------------------
void main( )
{
int arraysize = 10;
float array[arraysize];
int i, j, alreadyStored;
float num;
i = 0;
while (i < arraysize)
{
printf("Enter a number:\n");
//read an integer from a user input and store it in num1
scanf("%f", &num);
//check if the number is already stored in the array
alreadyStored = 0;
for (j = 0; j < i; j++)
{
if (array[j] == num)
{
alreadyStored = 1;
}
}
//Only if the same number is not in the array yet
if (alreadyStored == 0)
{
array[i] = num;
i++;
}
}
printf("The array contains the following:\n");
i = 0;
while (i < arraysize)
{
printf("%f\n", array[i]);
i++;
}
return;
}

A field is a group of related records that can be identified by the user with a name, type, and size.

Rick is a fan of logic-based games. However, he is bored of the classic ones, like Sudoku and Mastermind, since he has solved so many of them. Recently he found a new game in which one is given a string with some question marks in it. The objective is to replace all of the question marks with letters (one letter per question mark) in such a way that no letter appears next to another letter of the same kind.
Write a function:
def solution(riddle)
that, given a string riddle, returns a copy of the string with all of the question marks replaced by lowercase letters (a-z) in such a way that the same letters do not occur next to each other. The result can be any of the possible answers as long as it fulfils the above requirements.
Examples:
1. Given riddle = "ab?ac?", your function might return "abcaca". Some other possible results are 'abzacd", "abfacf".
2. Given riddle = "rd?e?wg??", your function might return "rdveawgab".
3. Given riddle = "????????", your function might return "codility".
Write an efficient algorithm for the following assumptions:
• the length of the string is within the range [1..100,000);
• string riddle consists only of lowercases letters (a - z) or '?';
• it is always possible to turn string 'riddle' into a string without two identical consecutive letters.

You have been given an encrypted copy of the Final exam study guide here, but how do you decrypt and read it???

Along with the encrypted copy, some mysterious person has also given you the following documents:

helloworld.txt -- Maybe this file decrypts to say "Hello world!". Hmmm.

hints.txt -- Seems important.

In a file called pa11.py write a method called decode(inputfile,outputfile). Decode should take two parameters - both of which are strings. The first should be the name of an encoded file (either helloworld.txt or superdupertopsecretstudyguide.txt or yet another file that I might use to test your code). The second should be the name of a file that you will use as an output file. For example:

decode("superDuperTopSecretStudyGuide.txt" , "translatedguide.txt")

Your method should read in the contents of the inputfile and, using the scheme described in the hints.txt file above, decode the hidden message, writing to the outputfile as it goes (or all at once when it is done depending on what you decide to use).
