"Why do the linked stack and queue implementations not include iterators, as in the linked list classes of Chapter 16? Are there cases in which a stack or queue might need to be traversed privately, even if access cannot be provided publicly? If so, should an iterator be used for these cases?"
Answer:
Explanation:
A linked stack is a LIFO (last in, first out) while a queue is a FIFO (first in, first out) data structure. This means that you can only access and modify the first or last elements of the stack or queue repectively. Therefore, there is no use for iterators in such a data structure which is why they do not exist. Iterators are mainly for traversing sequential access or random access within the given data structure which is not possible with these data structures, but is possible with lists. A stack or queue would either be made automatic so that it is completely private or simply made public so that it can be accessed by other methods and classes, regardless iterators would not be used.
As of Spring 2020, in otder to get into the CS major, you must have a 3.0 GPA or better in cs120, cs210, and cs245. In this problem, you should write one function named get_gpa, which will calculate this GPA. This function should have one parameter, which will be a dictionary of grades in computer science courses. You can assume that the dictionary will always have the keys 'cs120', 'cs210', and 'cs245', but it also might contain some names of other courses too. The values associated with each key will be a float representeing the GPA-style grade for that class. For instance, the parameter dictionary might look like: {'cs120':4.0 'cs245':3.0, 'cs210':2.0}. Some examples:
get_gpa({'cs110': 4.0, 'cs245':3.0, 'cs335':4.0, 'cs120':3.0, 'cs210':3.0}) should return 3.0.
get_gpa({'cs110': 4.0, 'cs120':3.0, 'cs245':2.0, 'cs210':1.0}) should return 2.0.
get_gpa({'cs245':4.0, 'cs120':3.0, 'cs245':2.0}) should return 3.0.
Make sure to include only the one function in your file.
Answer:
The function is as follows:
def get_gpa(mydict):
gpa = 0
kount = 0
for course_code, gp in mydict.items():
if course_code == 'cs120' or course_code == 'cs210' or course_code == 'cs245':
gpa += float(gp)
kount+=1
return (gpa/kount)
Explanation:
This defines the function
def get_gpa(mydict):
This initializes gpa to 0
gpa = 0
This initializes kount to 0
kount = 0
This iterates through the courses
for course_code, gp in mydict.items():
If course code is cs120 or cs210 or cs245
if course_code == 'cs120' or course_code == 'cs210' or course_code == 'cs245':
The gpa is added
gpa += float(gp)
And the number of courses is increased by 1
kount+=1
This returns the gpa
return (gpa/kount)

Suppose we define a WaitlistEntry as follows:
typedef struct{
int iPriority; /* Priority of the student to be enrolled */
int iStudentID; /* ID of the student */
}
WaitlistEntry;
Below are different implements of a function to create a WaitlistEntry from given iPriority and iStudentID data. Some of these implementations are flawed. Identify them and describe what is wrong with them briefly:
WaitlistEntry createWL( int iPriority, int iStudentlD )
WaitlistEntry w,
w.iPriority iPriority;
w.iStudentlD iStudentlD;
return w;
a. correct
b. incorrect, leaks memory
c. incorrect, syntax error
d. incorrect, data will be overwritten by next function call
Answer:
You have syntax errors, but I don't know if it happened when you posted this question, nevertheless
Explanation:
Correct code:
WaitlistEntry createWL( int iPriority, int iStudentID ) { // Opening Brace
WaitlistEntry w; // Should be ; not ,
w.iPriority = iPriority; // Assign Missing
w.iStudentID = iStudentID; // Assign Missing
return w;
} // Closing Brace
// Also note: iStudentID this actually has an 'l' which is LD. Not ID, this is why I assume these errors happened when posting the question.

HLOOKUP is used for Horizontal Data look ups while VLOOKUP is for Vertical Data look ups
Select one:
True
False
Answer:
True
Explanation:
Both HLOOKUP and VLOOKUP are excel functions used for searching through tables for a specified lookup value to either get an exact or approximate match. The VLOOK and HLOOKUP functions have identical syntax which only differs with the HLOOKUP requiring the row index number to search through the rows while, VLOOKUP requires the column index number to search through the columns. Other than this difference, the other syntax values are the same.
VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])
HLOOKUP(lookup_value, table_array, row_index_num, [range_lookup])

Answer:
A. 9
B. 16
C. Number of addresses = 12 number of data lines = 16
Explanation:
The capacity of this chip is 512 x 8
That is 512 words and these words have 8 bits
A. The number of the address lines would be
log2(512) = 2⁹
So the answer is 9
B. The total number of chips required
= 512 x 8 = 4096
(4096 x 2)/ 512 = 16

I run an online e-commerce store and lately its been very difficult keeping track of customer detail, incoming orders, keyword generation etc. One solution that I thought about would be an application that controls all of that for me. In order to accomplish this I would first need to design and create a GUI that contains all of the necessary buttons and displays for the information. Then I would need to code a webscraper using Python to grab all of the data from e-commerce store as soon as it becomes available, organize it, and display it within the GUI.

Explanation:
Consider the following incomplete method. Method findNext is intended to return the index of the first occurrence of the value val beyond the position start in array arr. I returns index of first occurrence of val in arr /! after position start; // returns arr.length if val is not found public int findNext (int[] arr, int val, int start) int pos = start + 1; while condition '/ ) pos++ return pos; For example, consider the following code segment. int [ ] arr {11, 22, 100, 33, 100, 11, 44, 100); System.out.println(findNext (arr, 100, 2)) The execution of the code segment should result in the value 4 being printed Which of the following expressions could be used to replace /* condition */ so that findNext will work as intended?
(A) (posarr.length) &&(arr [pos]- val)
(B) (arr [pos] != val) && (pos < arr. Îength)
(C) (pos
(D) (arr [pos} == val) && (pos < arr. length)
(E) (pos
Answer:
B)
Explanation:
The while loop runs as long as two conditions are satisfied, as indicated by the && logical operator.
The first condition- arr[pos] != val
checks to see if the value in the array index, pos, is equal to the given value and while it is not equal to it, the second condition is checked.
The second condition(pos < are.length), checks to see if the index(pos) is less than the length of the array. If both conditions are true, the program execution enters the while loop.
The while loop is only terminated once arr[pos] == Val or pos == arr.length.
Create a map using the Java map collection. The map should have 4 entries representing students. Each entry should have a unique student ID for the key and a student name for the element value. The map content can be coded in directly, you do not have to allow a user to enter the map data. Your program will display both the key and the value of each element.
Answer:
In Java:
import java.util.*;
public class Main{
public static void main(String[] args) {
Map<String, String> students = new HashMap<>();
students.put("STUD1", "Student 1 Name");
students.put("STUD2", "Student 2 Name");
students.put("STUD3", "Student 3 Name");
students.put("STUD4", "Student 4 Name");
for(Map.Entry m:students.entrySet()){
System.out.println(m.getKey()+" - "+m.getValue()); }
}}
Explanation:
This creates the map named students
Map<String, String> students = new HashMap<>();
The next four lines populates the map with the ID and name of the 4 students
students.put("STUD1", "Student 1 Name");
students.put("STUD2", "Student 2 Name");
students.put("STUD3", "Student 3 Name");
students.put("STUD4", "Student 4 Name");
This iterates through the map
for(Map.Entry m:students.entrySet()){
This prints the details of each student
System.out.println(m.getKey()+" - "+m.getValue()); }

When adding delegates to his mailbox, which role should Joel use if he would like the user to be able to read and create items in a particular folder?
- editor
- publishing editor
- author
- manager
Answer:
publishing editor
Explanation:
In this scenario, the role that he should choose for the delegates would be publishing editor. This role will allow them to create, read, modify, and delete all items within a given folder, and create subfolders. The other options listed either do not give access to create/modify existing files or simply only give all these rights with files that the user creates but not files that already existed in the folder. Therefore, this would be the best role for what Joel wants to accomplish.
Write a function named word_beginnings that has two parameters line a string ch a character Return a count of words in line that start with ch. For the purposes of this exercise a word is preceeded by a space. Hint: add a space to the beginning of line For example if line is 'row row row your raft' and ch is 'r' the value 4 will be returned. Note: You can use lists in this question but try to solve it without lists.
Answer:
The function in Python is as follows:
def word_beginnings(line, ch):
count = 0
lines =line.split(" ")
for word in lines:
if word[0] == ch:
count+=1
return count
Explanation:
This defines the function
def word_beginnings(line, ch):
This initializes count to 0
count = 0
This splits line into several words
lines =line.split(" ")
This iterates through each word
for word in lines:
This checks if the first letter of each word is ch
if word[0] == ch:
If yes, increment count by 1
count+=1
Return count
return count

Many companies use telephone numbers like 555-GET-FOOD so the number is easier for their customers to remember. On a standard telephone, the alphabetic letters are mapped to numbers in the following fashion: A, B, and C = 2 D, E, and F = 3 G, H, and I = 4 J, K, and L = 5 M, N, and O = 6 P, Q, R, and S = 7 T, U, and V = 8 W, X, Y, and Z = 9 Write a program that asks the user to enter a 12-character telephone number in the format: XXX-XXX-XXXX. Acceptable characters (X's) are A-Z and a-z. Your program should check for: The length of the phone number is correct. The dashes are included and are in the correct positions. There are no characters in the illegal characters in the string. The application should display the telephone number with any alphabetic characters that appeared in the original translated to their numeric equivalent. If the input string is not entirely correct then you should print an error message. For example, if the user enters 555-GET-FOOD the program should display 555-438-3663. If the user enters 123-456-7890, the program should display 123-456-7890. Rules: You must have one function (in addition to main()) that converts an alphabetic character to a digit. Or you can have one function that coverts all characters to digits. You can make your own function or use a built-in function if one exists.
Answer:
The program in Python is as follows:
def convertt(phone):
splitnum = phone.split ('-')
valid = True
count = 0
err = ""
numphone = ""
if len(phone) != 12:
err = "Invalid Length"
valid = False
elif phone[3] != '-' or phone[7] != '-':
err = "Invalid dash [-] location"
valid = False
while valid== True and count < 3:
for ch in splitnum[count]:
if ch.isdigit():
numphone += ch
elif ch.upper()in 'ABC':
numphone += '2'
elif ch.upper()in 'DEF':
numphone += '3'
elif ch.upper()in 'GHI':
numphone += '4'
elif ch.upper() in 'JKL':
numphone += '5'
elif ch.upper()in 'MNO':
numphone += '6'
elif ch.upper()in 'PQRS':
numphone += '7'
elif ch.upper()in 'TUV':
numphone += '8'
elif ch.upper()in 'WXYZ':
numphone += '9'
else:
valid = False
err = "Illegal character in phone number"
if count!=2:
numphone += '-'
count += 1
if valid == False:
print (err)
else:
print ("Phone Number", numphone)
phone = input("Phone number: ")
convertt(phone)

This is absolutely true. A shining example of this is with smartphones. Before Apple introduced the world to the iPhone, most smartphones had actual keyboards, zero touchscreen capabilities, could barely browse the internet, and had very small displays. After the iPhone was released in 2007, companies immediately scrambled to come out with phones that looked uncannily similar to Apple's. Why? Because Apple's phone was designed well. It's pretty amazing how immediate the shift was. In fact, I recomend you look up "Smartphones before and after iPhone" online. It's pretty cool. Here's an image example: https://www.redmondpie.com/image-showing-phones-before-and-after-iphone-x-revisits-how-android-market-still-tends-to-copy-iphone/
