A. Shopping mall movie rental kiosk assuming the user rarely ever rents movies
B. Amazon's create an account process
C. A teacher evaluation form that a student fills out once
D. None of the above
E. All of the above

Answers

Answer 1

Answer:

B. Amazon's create an account process

Explanation:

The Keystroke-Level Model (KLM) is a cognitive modeling tool which can be used in predicting the performances carried out by human on interface designs. It's the most "practical" of the GOMS methodologies.

This model tends to predict how long it will take for the completion of a routine task by an expert user. There should be no errors.

So, Option B is correct because GOMS/KLM is an evaluation tool which fits in the evaluation of Amazon's create an account process.

When an object reference is passed as a parameter to a method, modifying the members of that object from inside the method will result in a change to that object as seen from the client.
a. True
b. False

Answers

Answer:

A) True

Explanation:

Objects are known as reference types, meaning that they are always accessed by references, not copied. When a method is called, passing an object to it, Java passes a reference of that object to the method and when that reference is modified, the changes can be seen in the object itself. Therefore a mutable object can be mutated anywhere- either from where it is created or by a method it is passed to. Hence the need to always use privacy modifier keywords such as public, private or protected, to determine the exposure of class properties and methods.

Which statement correctly creates a set named colors that contains the 7 colors in a rainbow?
a. colors = ["red", "orange", "yellow" "green", "blue", "indigo", "violet"]
b. colors = {red, orange, yellow, green, blue, indigo, violet}
c. colors = [red, orange, yellow, green, blue, indigo, violet]
d. colors = {"red", "orange", "yellow", "green", "blue", "indigo", "violet"}

Answers

Answer:  d. colors = {"red", "orange", "yellow", "green", "blue", "indigo", "violet"}

Explanation:

We use "{}" to write a set in it.

Also, the names of the colors are strings so we use inverted commas ("") to express them.

So, the set named colors that contains the 7 colors in a rainbow will be:

colors = {"red", "orange", "yellow", "green", "blue", "indigo", "violet"}

Hence, the correct option is d.

Compute their Cartesian product, AxB of two lists. Each list has no more than 10 numbers.

For example, given the two input lists:
A = [1,2]
B = [3,4]

then the Cartesian product output should be:
AxB = [(1,3),(1,4),(2,3),(2,4)]

Answers

Answer:

The program written in Python is as follows: (See Attachments for source file and output)

def cartesian(AB):

     if not AB:

           yield ()

     else:

           for newlist in AB[0]:

                 for product in cartesian(AB[1:]):

                       yield (newlist,)+product  

A = []

B = []

alist = int(input("Number of items in list A (10 max): "))

while(alist>10):

     alist = int(input("Number of items in list A (10 max): "))

blist = int(input("Number of items in list B (10 max): "))

while(blist>10):

     blist = int(input("Number of items in list B (10 max): "))

print("Input for List A")

for i in range(alist):

     userinput = int(input(": "))

     A.append(userinput)

print("Input for List B")  

for i in range(blist):

     userinput = int(input(": "))

     B.append(userinput)  

print(list(cartesian([A,B])))

Explanation:

The function to print the Cartesian product is defined here

def cartesian(AB):

This following if condition returns the function while without destroying lists A and B

    if not AB:

         yield ()

If otherwise

    else:

The following iteration generates and prints the Cartesian products

         for newlist in AB[0]:

              for product in cartesian(AB[1:]):

                   yield (newlist,)+product

The main method starts here

The next two lines creates two empty lists A and B

A = []

B = []

The next line prompts user for length of list A

alist = int(input("Number of items in list A (10 max): "))

The following iteration ensures that length of list A is no more than 10

while(alist>10):

    alist = int(input("Number of items in list A (10 max): "))

The next line prompts user for length of list B

blist = int(input("Number of items in list B (10 max): "))

The following iteration ensures that length of list B is no more than 10

while(blist>10):

    blist = int(input("Number of items in list B (10 max): "))

The next 4 lines prompts user for input and gets the input for List A

print("Input for List A")

for i in range(alist):

    userinput = int(input(": "))

    A.append(userinput)

The next 4 lines prompts user for input and gets the input for List B

print("Input for List B")  

for i in range(blist):

    userinput = int(input(": "))

    B.append(userinput)

This line calls the function to print the Cartesian product

print(list(cartesian([A,B])))

Write a statement to create a Google Guava Multimap instance which contains student ids as keys and the associated values are student profiles.

Answers

Answer: provided in the explanation section

Explanation:

Note: take note for indentation so as to prevent error.

So we import com.google.common.collect.Multimap;

import java.util.Collection;

import java.util.Map;

class Main {

   public static void main(String[] args) {

       // key as studentId and List of Profile as value.

       Multimap<String,Profile> multimap = ArrayListMultimap.create();

       multimap.put("id1", new ExamProfile("examStudentId1"));

       multimap.put("id1", new ELearningProfile("userId1"));

       multimap.put("id2", new ExamProfile("examStudentId2"));

       multimap.put("id2", new ELearningProfile("userId2"));

       // print the data now.

       for (Map.Entry<String, Collection<Profile>> entry : multimap.entrySet()) {

           String key = entry.getKey();

           Collection<String> value =  multimap.get(key);

           System.out.println(key + ":" + value);

       }

   }

}

// assuming String as the studentId.

// assuming Profile as the interface. And Profile can multiple implementations that would be

// specific to student.

interface Profile {

}

class ExamProfile implements Profile {

   private String examStudentId;

   public ExamProfile(String examStudentId) {

       this.examStudentId = examStudentId;

   }

}

class ELearningProfile implements Profile {

   private String userId;

   public ELearningProfile(String userId) {

       this.userId = userId;

   }

}

This code is able to iterate through all entries in the Google Guava multimap and display all the students name in the associated students profile.

Write a function called count_occurrences that takes two strings. The second string should only be one character long. The function should return how many times the second string occurs in the first string.

Answers

Answer:

Here is the Python function:

def count_occurrences (string1 , string2):  # method that takes two strings as parameter and returns how many times second string occurs in first

   count = 0  #counts number of occurrence of string2 in string1

   for word in string1:  #iterates through each word of the string1

       for character in word:  #iterates through each character of each word in string1

           if character == string2:  # checks if the character in string1 is equal to the character of string2

               count = count + 1  #adds 1 to the count of string2 in string1

   return count  #returns number of times the string2 occurs in string1

#in order to check the working of the function add the following lines to the code:    

first_str = input("Enter the first string: ")  #prompts user to enter first string

second_str = input("Enter the second string (one character long): ") #prompts user to enter second string which should be one character long

occurrence = count_occurrences(first_str,second_str)  #calls count_occurrences method by passing both strings to it

print(second_str,"occurs",occurrence,"times in",first_str) #prints how many times the second_str occurs in the first_str on output screen

Explanation:

The program is well explained in the comments added to each statement of the above code. I will explain the program with an example:

Suppose

string1 = "hello world"

string2 = 'l'

So the method count_occurrences() should return how many times l occurs in hello world.

count is used to count the number of occurrences of l in hello world. It is initialized to 0.

The first loop iterates through each word of string1. The first word of string1 is "hello"

The second loop iterates through each character/letter of each word. So the first letter of "hello" word is 'h'.

The if condition if character == string2: checks if the character is equal to string2 i.e. l.

character = "h"

string2 = "l"

The are not equal so the program moves to the next character of word hello which is e. The if condition again evaluates to false because e is not equal to l. So the program moves to the next character of word hello which is l.

This time the if condition evaluates to true because

character = "l"

string2 = "l"

character == string2

l == l

So the if part is executed which has the following statement:

count = count + 1

So the count is added to 1. count was 0 previously. Now

count = 1

Next the program moves to the next character of word hello which is l. This time the if condition evaluates to true because the character l matches with string2. So count is again incremented to 1. count = 2.

Next the program moves to the next character of word hello which is o. The if condition evaluates to false as o does not match with string2 i.e. l. So the count remains 2.

Next the first loop moves to the next word of the string1 = "world". The inner (second) for loop iterates through each character of "world" from "w" to "d" and checks if any character is equal to string2. Only one character is equal to string2 in "world". So count is incremented to 1. Hence count = 3

After the loop ends the statement return count returns the number of times string2 occurs in the string1. So the output is:

l occurs 3 times in hello world  

Answer:

def count_occurrences(sentence, thing_to_count):

   times = 0

   for word in sentence:

       for letter in word:

           if letter == thing_to_count: times += 1

   return times
