In python:
i = 1
lst1 = ([])
lst2 = ([])
while i <= 5:
person1 = int(input("Enter the salary individual 1 got in year {}".format(i)))
person2 = int(input("Enter the salary individual 1 got in year {}".format(i)))
lst1.append(person1)
lst2.append(person2)
i += 1
if sum(lst1) > sum(lst2):
print("Individual 1 has the highest salary")
else:
print("Individual 2 has the highest salary")
This works correctly if the two individuals do not end up with the same salary overall.
Explain why it is not necessary for a program to be completely free of defects before it is delivered to its customers?
Answer:
Testing is done to show that a program is capable of performing all of its functions and also it is done to detect defects.
It is not always possible to deliver a 100 percent defect free program
A program should not be completely free of all defects before they are delivered if:
1. The remaining defects are not really something that can be taken as serious that may cause the system to be corrupt
2. The remaining defects are recoverable and there is an available recovery function that would bring about minimum disruption when in use.
3. The benefits to the customer are more than the issues that may come up as a result of the remaining defects in the system.

Which query is used to list a unique value for V_CODE, where the list will produce only a list of those values that are different from one another?
a. SELECT ONLY V_CODE FROM PRODUCT;
b. SELECT UNIQUE V_CODE FROM PRODUCT;
c. SELECT DIFFERENT V_CODE FROM PRODUCT;
d. SELECT DISTINCT V_CODE FROM PRODUCT;
Answer:
d. SELECT DISTINCT V_CODE FROM PRODUCT;
Explanation:
The query basically lists a unique value for V_CODE from PRODUCT table.
Option a is incorrect because it uses ONLY keyword which does not use to list a unique value for V_CODE. Instead ONLY keyword is used to restrict the tables used in a query if the tables participate in table inheritance.
Option b is incorrect because it is a constraint that ensures that all values in a column are unique.
Option c is incorrect because DIFFERENT is not a keyword
Option d is correct because the query uses SELECT statement and DISTINCT is used to select only distinct or different values for V_CODE.
The query that should be used for a unique value is option d.
The following information should be considered:
The query listed the unique value for V_CODE arise from the PRODUCT table.Option A is wrong as it used ONLY keyword that does not represent the unique value. Option B is wrong as it is constraint where the columns values are considered to be unique.Option C is wrong as DIFFERENT does not represent the keyword. Option D is right as query applied SELECT and DISTINCT that represent different values.Therefore we can conclude that the correct option is D.

This assignment requires you to write a program to analyze a web page HTML file. Your program will read one character at a time from the file specifying the web page, count various attributes in the code for the page, and print a report to the console window giving information about the coding of the page.
Note that a search engine like Google uses at least one technique along similar lines. To calculate how popular (frequently visited or cited) a web page is, one technique is to look at as many other worldwide web pages as possible which are relevant, and count how many links the world's web pages contain back to the target page.
Learning Objectives
To utilize looping structures for the first time in a C++ program
To develop more sophisticated control structures using a combination of selection and looping
To read data from an input file
To gain more experience using manipulators to format output in C++
To consider examples of very simple hypertext markup language (HTML)
Use UNIX commands to obtain the text data files and be able to read from them
Problem Statement
Your program will analyze a few things about the way in which a web page is encoded. The program will ask the user for the name of a file containing a web page description. This input file must be stored in the correct folder with your program files, as discussed in class, and it must be encoded using hypertext markup language, or HTML. The analysis requires that you find the values of the following items for the page:
number of lines (every line ends with the EOLN marker; there will be an EOLN in front of the EOF)
number of tags (includes links and comments)
number of links
number of comments in the file
number of characters in the file (note that blanks and EOLNs do count)
number of characters inside tags
percentage of characters which occur inside tags, out of the total
Here is an example of a very simple HTML file:
Course Web Page
This course is about programming in C++.
Click here
You may assume that the HTML files you must analyze use a very limited subset of basic HTML, which includes only the following "special" items:
tag always starts with '<' and ends with >
link always starts with "
comment always starts with ""
You may assume that a less-than symbol (<) ALWAYS indicates the start of a tag. A tag in HTML denotes an item that is not displayed on the web page, and often gives instructions to the web browser. For example, indicates that the next item is the overall title of the document, and indicates the end of that section. In tags, both upper and lowercase letters can be used.
Note on links and comments: to identify a link, you may just look for an 'a' or 'A' which occurs just after a '<'. To identify a comment, you may just look for a '!' which follows just after a '' (that is, you do not have to check for the two hyphens).
You may assume that these are the only HTML language elements you need to recognize, and that the HTML files you process contain absolutely no HTML syntax errors.
Note: it is both good style because readability is increased, and convenient, to declare named constants for characters that are meaningful, for example
const char TAG OPEN = '
Sample Input Files
Program input is to be read from a text file. Your program must ask the user for interactive input of the file name. You can declare a variable to store the file name and read the user's response
Miscellaneous Tips and Information
You should not read the file more than once to perform the analysis. Reading the file more than once is very inefficient.
The simplest, most reliable and consistent way to check for an end of file condition on a loop is by checking for the fail state, as shown in lectures. The eof function is not as reliable or consistent and is simply deemed "flaky" by many programmers as it can behave inconsistently for different input files and on different platforms.
You may use only while loops on this project if you wish; you are not required to choose amongst while, do while and/or for loops until project 4 and all projects thereafter. Do not create any functions other than main() for this program. Do not use data structures such as arrays. You may only have ONE return statement and NO exit statements in your code. You may only use break statements inside a switch statement in the manner demonstrated in class; do not use break or continue statements inside loops.

What is the output, if userVal is 5? int x; x = 100; if (userVal != 0) { int tmpVal; tmpVal = x / userVal; System.out.print(tmpVal); }
Answer:
The output is 20
Explanation:
This line divides the value of x by userVal
tmpVal = x / userVal;
i.e.
tmpVal = 100/5
tmpVal = 20
This line then prints the value of tmpVal
System.out.print(tmpVal);
i.e 20
Hence, The output is 20
Which error produces incorrect results but does not prevent the program from running? a. syntax b. logic c. grammatical d. human e. None of the above
Answer:
Logic Error
Explanation:
I'll answer the question with the following code segment.
Program to print the smallest of two integers (written in Python)
num1 = int(input("Num 1: "))
num2 = int(input("Num 2: "))
if num1 < num2:
print(num2)
else:
print(num1)
The above program contains logic error and instead will display the largest of the two integers
The correct logic is
if num1 < num2:
print(num1)
else:
print(num2)
However, the program will run successfully without errors
Such errors are called logic errors

List A is an anagram of list B if the following two conditions are true: 1.list A and list B have the same number of elements 2.each element of list A occurs the same number of times in list A and list BFor example, [3, 2, 4, 1, 2] and [2, 2, 3, 1, 4] are anagram of each other, but [2, 3, 1, 2] and [1, 3, 1, 2] are not. Write a function named isAnagram that takes two lists of integers as parameters: lstA and lstB. The function isAnagram should return the bool value True if lstA is an anagram of lstB and False otherwise. The following is an example of correct output: >>> print(isAnagram([14, 10, 19], [10, 14, 19]))True

Explanation:
You are given an array of integers, each with an unknown number of digits. You are also told the total number of digits of all the integers in the array is n. Provide an algorithm that will sort the array in O(n) time no matter how the digits are distributed among the elements in the array. (e.g. there might be one element with n digits, or n/2 elements with 2 digits, or the elements might be of all different lengths, etc. Be sure to justify in detail the run time of your algorithm.
Answer:
Explanation:
Since all of the items in the array would be integers sorting them would not be a problem regardless of the difference in integers. O(n) time would be impossible unless the array is already sorted, otherwise, the best runtime we can hope for would be such a method like the one below with a runtime of O(n^2)
static void sortingMethod(int arr[], int n)
{
int x, y, temp;
boolean swapped;
for (x = 0; x < n - 1; x++)
{
swapped = false;
for (y = 0; y < n - x - 1; y++)
{
if (arr[y] > arr[y + 1])
{
temp = arr[y];
arr[y] = arr[y + 1];
arr[y + 1] = temp;
swapped = true;
}
}
if (swapped == false)
break;

How does a computer interact with its environment? How is data transferred on a real computer from one hardware part to another? Describe the importance of the human interaction in the computing system.
Answer:
Explanation:
A computer system can interact with its environment using hardware that does so such as cameras, robotic arms, thermometers, smart devices etc. These hardware devices gather information from the environment and transfer it to the computer system in a format known as bits through binary electrical impulses. If the system is designed to be autonomous then the only human interaction needed would be the initial setup of the system and its hardware, once this is done the system does not need any more human interaction as long as nothing breaks.
Write a function that takes in a sequence s and a function fn and returns a dictionary. The values of the dictionary are lists of elements from s. Each element e in a list should be constructed such that fn(e) is the same for all elements in that list. Finally, the key for each value should be fn(e)
def group_by(s, fn):
""" >>> group_by([12, 23, 14, 45], lambda p: p // 10)
{1: [12, 14], 2: [23], 4: [45]}
>>> group_by(range(-3, 4), lambda x: x * x)
{0: [0], 1: [-1, 1], 4: [-2, 2], 9: [-3, 3]}
"""
Use Python
Answer:
Here is the Python function:
def group_by(s, fn): #method definition
group = {} #dictionary
for e in s: #for each element from s
key = fn(e) #set key to fn(e)
if key in group: #if key is in dictionary group
group[key].append(e) #append e to the group[key]
else: #if key is not in group
group[key] = [e] #set group[key] to [e]
return group #returns dictionary group
Explanation:
To check the working of the above function call the function by passing a sequence and a function and use print function to display the results produced by the function:
print(group_by([12, 23, 14, 45], lambda p: p // 10))
print(group_by(range(-3, 4), lambda x: x * x))
function group_by takes in a sequence s and a function fn as parameters. It then creates an empty dictionary group. The values of the dictionary are lists of elements from s. Each element e in a list is constructed such that fn(e) is the same for all elements in that list. Finally, the key for each value is fn(e). The function returns a dictionary. The screenshot of the program along with its output is attached.
Write a function called matches that takes two int arrays and their respective sizes, and returns the number of consecutive values that match between the two arrays starting at index 0. Suppose the two arrays are {3, 2, 5, 6, 1, 3} and {3, 2, 5, 2, 6, 1, 3} then the function should return 3 since the consecutive matches are for values 3, 2, and 5.
Answer:
Written in C++
int matches(int arr1[], int arr2[], int k) {
int count = 0;
int length = k;
for(int i =0; i<length; i++) {
if(arr1[i] == arr2[i]) {
count++;
}
}
return count;
}
Explanation:
This line defines the function
int matches(int arr1[], int arr2[], int k) {
This line initializes count to 0
int count = 0;
This line initializes length to k
int length = k;
This line iterates through the array
for(int i =0; i<length; i++) {
The following if statement checks for matches
if(arr1[i] == arr2[i]) {
count++;
}
}
This returns the number of matches
return count;
}

To prevent any unnecessary injuries to small adults and the elderly from a deploying airbag, these
individuals should
as possible.
A. position their seats as far forward
B. position their seats as far back
c. recline their seats as far back
D. none of the above
Answer:
B. position their seats as far back
Explanation:
An airbag can be defined as a vehicle safety device (bag) that is designed to be inflated and eventually deflated in an extremely rapid or quick manner during an accident or collision.
Basically, an airbag refers to an occupant-restraint safety device installed on vehicles to protect both the driver and front-seat passenger in the event of an accident or collision. An airbag typically comprises of an impact sensor, flexible fabric bag, airbag cushion and an inflation module.
In order to prevent any unnecessary injuries to small adults and the elderly from a deploying airbag, these individuals should position their seats as far back as possible. This ultimately implies that, both the driver and the front-seat passenger are advised not to position too close to the dashboard; the seats should be as far back as possible.

Write two statements to read in values for my_city followed by my_state. Do not provide a prompt. Assign log_entry with current_time, my_city, and my_state. Values should be separated by a space. Sample output for given program if my_city is Houston and my_state is Texas: 2014-07-26 02:12:18: Houston Texas Note: Do not write a prompt for the input values. 1 current_time = '2014-07-26 02:12:18:' 2 my_city = "' 3 my_state = "" 4 log_entry - "' 1 test passed 6 print(log_entry) All tests passed Run Run
Answer:
Here is the program:
current_time = '2014-07-26 02:12:18:'
my_city = ''
my_state = ''
log_entry = ''
my_city = input("") #reads in value for my_city
my_state = input("") #reads in value for my_state
log_entry = current_time + ' ' + my_city + ' ' + my_state #concatenates current_time, my_city and my_state values with ' ' empty space between them
print(log_entry)
Explanation:
You can also replace
log_entry = current_time + ' ' + my_city + ' ' + my_state
with
log_entry = f'{current_time} {my_city} {my_state}'
it uses f-strings to format the strings
If you want to hard code the values for my_city and my_state then you can replace the above
my_city = input("")
my_state = input("")
with
my_city = "Houston"
my_state = "Texas"
but if you want to read these values at the console from user then use the input() method.

The code is intended to take two strings, s1 and s2 followed by a whole number, n, as inputs from the user, then print a string made up of the first n letters of s1 and the last n letters of s2. Your job is to fix the errors in the code so it performs as expected (see the sample run for an example).
Sample run

int n = scan.nextInt(); //reads value of integer n from user
System.out.println(s1.substring(0,n) + s2.substring(s2.length() - n ));
} } //uses substring method to print a string made up of the first n letters of s1 and the last n letters of s2.
Explanation:
The errors were:
1.
Scanner scan = Scanner(System.in);
Here new keyword is missing to create object scan of Scanner class.
Corrected statement:
Scanner scan = new Scanner(System.in);
2.
String s1 = nextLine();
Here object scan is missing to call nextLine() method of class Scanner
Corrected statement:
String s1 = scan.nextLine();
3.
String s2 = Scanner.nextLine();
Here class is used instead of its object scan to access the method nextLine
Corrected statement:
String s2 = scan.nextLine();
4.
String n = scan.nextLine();
Here n is of type String but n is a whole number so it should be of type int. Also the method nextInt will be used to scan and accept an integer value
Corrected statement:
int n = scan.nextInt();
5.
System.out.println(s1.substring(1,n-1) + s2.substring(s1.length()-n));
This statement is also not correct
Corrected statement:
System.out.println(s1.substring(0,n) + s2.substring(s2.length() - n ));
This works as follows:
s1.substring(0,n) uses substring method to return a new string that is a substring of this s1. The substring begins at the 0th index of s1 and extends to the character at index n.
s2.substring(s2.length() - n ) uses substring method to return a new string that is a substring of this s2. The substring then uses length() method to get the length of s2 and subtracts integer n from it and thus returns the last n characters of s2.
