Now you are ready to implement a spell checker by using or quadratic. Given a document, your program should output all of the correctly spelled words, labeled as such, and all of the misspelled words. For each misspelled word you should provide a list of candidate corrections from the dictionary, that can be formed by applying one of the following rules to the misspelled word:
a) Adding one character in any possible position
b) Removing one character from the word
c) Swapping adjacent characters in the word
Your program should run from the command line as follows:
% ./spell_check
You will be provided with a small document named document1_short.txt, document_1.txt,
and a dictionary file with approximately 370k words named wordsEnglish.txt.
As an example, your spell checker should correct the following mistakes.
deciive -> decisive (Case A)
deciasion -> decision (Case B)
ocunry -> counry (Case C)

Which of the following is NOT a possible combination of values of the variables in this program when it finishes running?
A. tails has a value of O and heads has a value of 100
B. tails has a value of 100 and heads has a value of O
C. tails has a value of 20 and heads has a value of 20
D. tails has a value of 50 and heads has a value of 50
Answer:
Definitely D
Explanation:
When you flip a coin it’s a 50/50 chance. Meaning it’s equal.
Given that they are familiar with what the tails have a value of 50 variables stand for and heads have a value of 50, programmers will find it simpler to read and comprehend the code, hence option D is correct.
What is a combination of values of the variables?Almost all programming languages use a similar technique for saving values in variables: we place the variable name on the left side of the equal sign (=), and the value we wish to store on the right.
Print the variables in reverse order in addition to the entered order by typing the variables backward.
In addition to printing the sequence in reverse, print the double's int casting value by placing (int) before the variable name, tails has a value of 50 and heads has a value of 50, hence option D is correct.

6.22 LAB: Output values below an amount - methods
Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, and output all integers less than or equal to that value. Assume that the list will always contain less than 20 integers.
Ex: If the input is:
5 50 60 140 200 75 100
the output is:
50 60 75
The 5 indicates that there are five integers in the list, namely 50, 60, 140, 200, and 75. The 100 indicates that the program should output all integers less than or equal to 100, so the program outputs 50, 60, and 75. For coding simplicity, follow every output value by a space, including the last one.
Such functionality is common on sites like Amazon, where a user can filter results.
Write your code to define and use two methods:
public static void getUserValues(int[] myArr, int arrSize, Scanner scnr)
public static void outputIntsLessThanOrEqualToThreshold(int[] userValues, int userValsSize, int upperThreshold)

Navigational search - This occurs when the user is looking for a certain website. Then the name of the website will be entered into the search bar.
Informational search - This occurs when the user wants to get a certain information. For example, if user enters "what is computer" into the search bar, different results relating to the word "computer" will be gotten.
Transactional search - This occurs when the user wants a website that is interactive it which possess more interaction. An example is when the user wants to buying something, register for something or maybe download something
There are 2.54 centimeters in an inch, and there are 3.7854 liters in a U.S. gallon. Create a program named MetricConversion. Its main() method accepts an integer value from a user at the keyboard, and in turn passes the entered value to two methods. One converts the value from inches to centimeters and the other converts the same value from gallons to liters.
Answer:
Explanation:
The following Java code creates the program which calls asks the user for an input and then passes that input into two methods toInches, and toGallons. Then the main method saves the returned values in variables and prints out a statement for each.

Write an application that uses String method region-Matches to compare two stringsinput by the user. The application should input the number of characters to be compared andthe starting index of the comparison. The application should state whether the comparedcharacters are equal. Ignore the case of the characters when performing the comparison.
Answer:
Explanation:
The following program creates a function called region_Matches that takes in two strings as arguments as well as an int for starting point and an int for amount of characters to compare. Then it compares those characters in each of the words. If they match (ignoring case) then the function outputs True, else it ouputs False. The test cases compare the words "moving" and "loving", the first test case compares the words starting at point 0 which outputs false because m and l are different. Test case 2 ouputs True since it starts at point 1 which is o and o.
class Brainly {
public static void main(String[] args) {
String word1 = "moving";
String word2 = "loving";
boolean result = region_Matches(word1, word2, 0, 4);
boolean result2 = region_Matches(word1, word2, 1, 4);
System.out.println(result);
System.out.println(result2);
}
public static boolean region_Matches(String word1, String word2, int start, int numberOfChars) {
boolean same = true;
for (int x = 0; x < numberOfChars; x++) {
if (Character.toLowerCase(word1.charAt(start + x)) == Character.toLowerCase(word2.charAt(start + x))) {
continue;
} else {
same = false;
break;
}

The hostel in which you plan to spend the night tonight offers very interesting rates, as long as you do not arrive too late. Housekeeping finishes preparing rooms by noon, and the sooner guests arrive after noon, the less they have to pay. You are trying to build a C program that calculates your price to pay based on your arrival time. Your program will read an integer (between 0 and 12) indicating the number of hours past noon of your arrival. For example, 0 indicates a noon arrival, 1 a 1pm arrival, 12 a midnight arrival, etc. The base price is 10 dollars, and 5 dollars are added for every hour after noon. Thankfully the total is capped at 53 dollars, so you'll never have to pay more than that. Your program should print the price (an integer) you have to pay, given the input arrival time.
Answer:
Answered below
Explanation:
// Python implementation
incrementAmount = 5
basePrice = 10
price = 0
arrivalHour = int(input("Enter arrival hour 0-12: ")
if arrivalHour < 0 or arrivalHour > 12:
print ("Invalid hour")
if arrivalHour == 0:
price = basePrice
else:
price = arrivalHour * incrementAmount
totalPrice = price + basePrice
if totalPrice > 53:
totalPrice = 53
print ("Your bill is $totalPrice")
If you have downloaded this book's source code from the companion Web site, you will find a file named text.txt in the Chapter 12 folder. (The companion Web site is at www.pearsonhighered/gaddis.) The text that is in the file is stored as on sen- tence per line. Write a program that reads the file's contents and calculates the average of words per sentence.
Answer:
Explanation:
The following python code loops through each line within a file called text.txt and counts all the words, then it divides this count by the number of sentences in the text file. Finally, output the average number of words per sentence.
f = open("text.txt", "r")
all_words = 0
sentences = 0
for x in f:
list = x.split(' ')
all_words += len(list)
sentences += 1
average = all_words / sentences
print("There are an average of " + str(average.__round__()) + " words in each sentence.")

What is the output of the following code?
int x = 6, y = 3, z=24, result=0;
result = 2*((z/(x-y))%y+10);
cout<< result<
Answer:
The output is 24
Explanation:
Given
The above code segment
Required
The output
We have (on the first line):
[tex]x = 6[/tex]
[tex]y = 3[/tex]
[tex]z=24[/tex]
[tex]result=0[/tex]
On the second line:
[tex]result = 2*((z/(x-y))\%y+10)[/tex]
Substitute the value of each variable
[tex]result = 2*((24/(6-3))\%3+10)[/tex]
Solve the inner brackets
[tex]result = 2*((24/3)\%3+10)[/tex]
[tex]result = 2*(8\%3+10)[/tex]
8%3 implies that, the remainder when 8 is divided by 3.
The remainder is 2
So:
[tex]result = 2*(2+10)[/tex]
[tex]result = 2*12[/tex]
[tex]result = 24[/tex]
Hence, the output is 24

how many stages needed to have powerful amplifier?
Power amplifier stages in a real circuit. Circuit diagram of a three stage practical audio power amplifier is shown in the figure below. Small signal transistor Q1 and its associated components form the voltage amplification stage.
Answer:
Generally you should pick an amplifier that can deliver power equal to twice the speaker's program/continuous power rating. This means that a speaker with a “nominal impedance” of 8 ohms and a program rating of 350 watts will require an amplifier that can produce 700 watts into an 8 ohm load.
Write a program whose input is two integers. Output the first integer and subsequent increments of 10 as long as the value is less than or equal to the second integer. Ex: If the input is: -15 30 the output is: -15 -5 5 15 25
Answer:
Explanation:
The following program is written in Python. It asks the user for two number inputs. Then it creates a loop that prints the first number and continues incrementing it by 10 until it is no longer less than the second number that was passed as an input by the user.
number1 = int(input("Enter number 1: "))
number2 = int(input("Enter number 2: "))
while number1 < number2:
print(number1)
number1 += 10
Suppose you are given a relation R with four attributes ABCD. For each of the following sets of FDs, assuming those are the only dependencies that hold for R, do the following: (a) Identify the candidate key(s) for R. (b) Identify the best normal form that R satisfies (1NF, 2NF, 3NF, or BCNF). (c) If R is not in BCNF, decompose it into a set of BCNF relations that preserve the dependencies.
1. C → D, C → A, B → C
2. B → C, D → A
3. ABC → D, D → A
4. A → B, BC → D, A → C
5. AB → C, AB → D, C → A, D → B
Solution :
1.
a). Candidate keys : [tex]$B$[/tex]
b). R is in [tex]$2F$[/tex] but not [tex]$3NF$[/tex]
c). C → [tex]$D$[/tex] and C → [tex]$A$[/tex], both causes violations of [tex]$BCNF$[/tex]. The way to obtain the join preserving decomposition is to decompose [tex]$R$[/tex] into [tex]$AC, BC$[/tex] and CD.
2.
a). Candidate keys : [tex]$BD$[/tex]
b). [tex]$R$[/tex] is in [tex]$1NF$[/tex] but not [tex]$2NF$[/tex].
c). Both B → [tex]$C$[/tex] and D → [tex]$A$[/tex] cause [tex]$BCNF$[/tex] violations. The decomposition : [tex]$AD $[/tex], [tex]$BC, BD$[/tex] is [tex]$BCNF$[/tex] and lossless and the join preserving.
3.
a). Candidate keys : [tex]$ABC, BCD$[/tex]
b). R is in [tex]$3NF$[/tex] but not [tex]$BCNF$[/tex]
c).[tex]$ABCD$[/tex] is not in [tex]$BCNF$[/tex] since D → [tex]$A$[/tex] and [tex]$D$[/tex] is not a key. But if we split up the [tex]$R$[/tex] as [tex]$AD,BCD$[/tex] therefore we cannot preserve dependency [tex]$ABC$[/tex] → D. So there is no [tex]$BCNF$[/tex] decomposition.
4.
a). Candidate keys : [tex]$A$[/tex]
b). R is in [tex]$2NF$[/tex] but not [tex]$3NF$[/tex]
c). BC → [tex]$D$[/tex] violates [tex]$BCNF$[/tex] since [tex]$BC$[/tex] does not contain the key. And we split up R as in [tex]$BCD, ABC$[/tex].
5.
a). Candidate keys : [tex]$AB, BC, CD, AD$[/tex]
b). [tex]$R$[/tex] is in [tex]$3NF$[/tex] but not [tex]$BCNF$[/tex].
c). C → [tex]$A$[/tex] and D → [tex]$B$[/tex] both causes a violations. The decomposition into [tex]$AC,BCD$[/tex] but this will not preserve [tex]$AB$[/tex] → C and [tex]$AB$[/tex] → D, and [tex]$BCD$[/tex] is still not [tex]$BCNF$[/tex] because [tex]$D$[/tex] → [tex]$B$[/tex]. So we need to decompose further into [tex]$AC,BD,CD$[/tex] However when we try to revive the lost functional dependencies by adding [tex]$ABC$[/tex] and [tex]$ABD$[/tex], we that these relations are not in [tex]$BCNF$[/tex] form. Therefore, there is no [tex]$BCNF$[/tex] decomposition.

Find the reference angle of the angle = 850°
Answer:
magine a coordinate plane. Let’s say we want to draw an angle that’s 144° on our plane. We start on the right side of the x-axis, where three o’clock is on a clock. We rotate counterclockwise, which starts by moving up. We keep going past the 90° point (the top part of the y-axis) until we get to 144°. We draw a ray from the origin, which is the center of the plane, to that point. Now we have a ray that we call the terminal side. But we need to draw one more ray to make an angle. We have a choice at this point. Our second ray needs to be on the x-axis. If we draw it from the origin to the right side, we’ll have drawn an angle that measures 144°. If we draw it to the left, we’ll have drawn an angle that measures 36°. This second angle is the reference angle. It’s always the smaller of the two angles, will always be less than or equal to 90°, and it will always be positive. Here’s an animation that shows a reference angle for four different angles, each of which is in a different quadrant. Notice how the second ray is always on the x-axis.

Which function deletes the first occurence of 3 in a list named listB ?
listB.clear(3)
listB(3)
listB delete(3)
listB.remove(3)
Answer:
[tex]listB.remove(3)[/tex]
Explanation:
Given
Options A to D
Required
Which deletes the first occurrence of 3
The options show that the question is to be answered using the knowledge of Python.
So, we analyze each of the options using Python syntax
(a) listB.clear(3)
In python, clear() is used to delete all elements of a list, and it does not take any argument i.e. nothing will be written in the bracket.
Hence, (a) is incorrect
(b) listB(3)
The above instruction has no meaning in Python
(c) listB delete(3)
The above instruction as written is an invalid syntax because of the space between listB and delete.
Also, it is an invalid syntax because lists in Python do not have the delete attribute
[tex](d)\ listB.remove(3)[/tex]
This removes the first occurrence of 3
Answer: listB delete(3)
