Explanation:
This corrects the scanner object
Scanner scan = new Scanner(System.in);
This line is correct
String str1 = scan.nextLine();
This copies str1 to str2
String str2 = str1;
This converts str1 to upper case

This prints str2
System.out.println(str2);
In Scheme, source code is data. Every non-atomic expression is written as a Scheme list, so we can write procedures that manipulate other programs just as we write procedures that manipulate lists.
Rewriting programs can be useful: we can write an interpreter that only handles a small core of the language, and then write a procedure that converts other special forms into the core language before a program is passed to the interpreter.
For example, the let special form is equivalent to a call expression that begins with a lambda expression. Both create a new frame extending the current environment and evaluate a body within that new environment. Feel free to revisit Problem 15 as a refresher on how the let form works.
(let ((a 1) (b 2)) (+ a b))
;; Is equivalent to:
((lambda (a b) (+ a b)) 1 2)
These expressions can be represented by the following diagrams:
Let Lambda
let lambda
Use this rule to implement a procedure called let-to-lambda that rewrites all let special forms into lambda expressions. If we quote a let expression and pass it into this procedure, an equivalent lambda expression should be returned: pass it into this procedure:
scm> (let-to-lambda '(let ((a 1) (b 2)) (+ a b)))
((lambda (a b) (+ a b)) 1 2)
scm> (let-to-lambda '(let ((a 1)) (let ((b a)) b)))
((lambda (a) ((lambda (b) b) a)) 1)
In order to handle all programs, let-to-lambda must be aware of Scheme syntax. Since Scheme expressions are recursively nested, let-to-lambda must also be recursive. In fact, the structure of let-to-lambda is somewhat similar to that of scheme_eval--but in Scheme! As a reminder, atoms include numbers, booleans, nil, and symbols. You do not need to consider code that contains quasiquotation for this problem.
(define (let-to-lambda expr)
(cond ((atom? expr) )
((quoted? expr) )
((lambda? expr) )
((define? expr) )
((let? expr) )
(else )))
CODE:
; Returns a function that checks if an expression is the special form FORM
(define (check-special form)
(lambda (expr) (equal? form (car expr))))
(define lambda? (check-special 'lambda))
(define define? (check-special 'define))
(define quoted? (check-special 'quote))
(define let? (check-special 'let))

Good information is characterized by certain properties. Explain how you understand these characteristtics of good information. Use examples to better explain your answer.
Answer:
here is your ans
Explanation:
Characteristics of good quality information can be defined as an acronym ACCURATE. These characteristics are interrelated; focus on one automatically leads to focus on other.
Accurate
Information should be fair and free from bias. It should not have any arithmetical and grammatical errors. Information comes directly or in written form likely to be more reliable than it comes from indirectly (from hands to hands) or verbally which can be later retracted.
Complete
Accuracy of information is just not enough. It should also be complete which means facts and figures should not be missing or concealed. Telling the truth but not wholly is of no use.
Cost-beneficial
Information should be analysed for its benefits against the cost of obtaining it. It business context, it is not worthwhile to spend money on information that even cannot recover its costs leading to loss each time that information is obtained. In other contexts, such as hospitals it would be useful to get information even it has no financial benefits due to the nature of the business and expectations of society from it.
User-targeted
Information should be communicated in the style, format, detail and complexity which address the needs of users of the information. Example senior managers need brief reports which enable them to understand the position and performance of the business at a glance, while operational managers need detailed information which enable them to make day to day decisions.
Relevant
Information should be communicated to the right person. It means person which has some control over decisions expected to come out from obtaining the information.
Authoritative
Information should come from reliable source. It depends on qualifications and experience and past performance of the person communicating the information.
Timely
Information should be communicated in time so that receiver of the information has enough time to decide appropriate actions based on the information received. Information which communicates details of the past events earlier in time is of less importance than recently issued information like newspapers. What is timely information depends on situation to situation. Selection of appropriate channel of communication is key skill to achieve.
Easy to Use
Information should be understandable to the users. Style, sentence structure and jargons should be used keeping the receiver in mind. If report is targeted to new-comer in the field, then it should explain technical jargons used in the report.
One of your start-ups uses error-correcting codes, which can recover the original message as long as at least 1000 packets are received (not erased). Each packet gets erased independently with probability 0.8. How many packets should you send such that you can recover the message with probability at least 99%
Answer:
Number of packets ≈ 5339
Explanation:
let
X = no of packets that is not erased.
P ( each packet getting erased ) = 0.8
P ( each packet not getting erased ) = 0.2
P ( X ≥ 1000 ) = 0.99
E(x) = n * 0.2
var ( x ) = n * 0.2 * 0.8
∴ Z = X - ( n * 0.2 ) / [tex]\sqrt{n*0.2*0.8}[/tex] ~ N ( 0.1 )
attached below is the remaining part of the solution
note : For the value of n take the positive number
What are the disadvantages of using a series circuit in a lighting system?
Answer:
Throughout the following segment, the disadvantages of the given topic are summarized.
Explanation:
It's indeed impossible to monitor each unit, but the entire series can be switched open or closed.Unless the series-connected components vary in any way, they include varying voltages through themselves which could create difficulty when you both need a certain voltage.Working with such positive and negative sequence loads on sequence is extremely challenging.Implement the above in c++, you will write a test program named create_and_test_hash.cc . Your programs should run from the terminal like so:
./create_and_test_hash should be "quadratic" for quadratic probing, "linear" for linear probing, and "double" for double hashing. For example, you can write on the terminal:
./create_and_test_hash words.txt query_words.txt quadratic You can use the provided makefile in order to compile and test your code. Resources have been posted on how to use makefiles. For double hashing, the format will be slightly different, namely as follows:
./create_and_test_hash words.txt query_words.txt double The R value should be used in your implementation of the double hashing technique discussed in class and described in the textbook: hash2 (x) = R – (x mod R). Q1. Part 1 (15 points) Modify the code provided, for quadratic and linear probing and test create_and_test_hash. Do NOT write any functionality inside the main() function within create_and_test_hash.cc. Write all functionality inside the testWrapperFunction() within that file. We will be using our own main, directly calling testWrapperFunction().This wrapper function is passed all the command line arguments as you would normally have in a main. You will print the values mentioned in part A above, followed by queried words, whether they are found, and how many probes it took to determine so. Exact deliverables and output format are described at the end of the file. Q1. Part 2 (20 points) Write code to implement double_hashing.h, and test using create_and_test_hash. This will be a variation on quadratic probing. The difference will lie in the function FindPos(), that has to now provide probes using a different strategy. As the second hash function, use the one discussed in class and found in the textbook hash2 (x) = R – (x mod R). We will test your code with our own R values. Further, please specify which R values you used for testing your program inside your README. Remember to NOT have any functionality inside the main() of create_and_test_hash.cc
You will print the current R value, the values mentioned in part A above, followed by queried words, whether they are found, and how many probes it took to determine so. Exact deliverables and output format are described at the end of the file. Q1. Part 3 (35 points) Now you are ready to implement a spell checker by using a linear or quadratic or double hashing algorithm. 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 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 100k words named wordsEN.txt. As an example, your spell checker should correct the following mistakes. comlete -> complete (case a) deciasion -> decision (case b) lwa -> law (case c)
Correct any word that does not exist in the dictionary file provided, (even if it is correct in the English language). Some hints: 1. Note that the dictionary we provide is a subset of the actual English dictionary, as long as your spell check is logical you will get the grade. For instance, the letter "i" is not in the dictionary and the correction could be "in", "if" or even "hi". This is an acceptable output. 2. Also, if "Editor’s" is corrected to "editors" that is ok. (case B, remove character) 3. We suggest all punctuation at the beginning and end be removed and for all words convert the letters to lower case (for e.g. Hello! is replaced with hello, before the spell checking itself).
Do NOT write any functionality inside the main() function within spell_check.cc. Write all functionality inside the testSpellingWrapper() within that file. We will be using our own main, directly calling testSpellingWrapper(). This wrapper function is passed all the command line arguments as you would normally have in a main

A profit of ₹ 1581 is to be divided amongst three partner P,Q and R in ratio 1/3:1/2:1/5.theshareof R will be?
Answer:
R's share = 306
Explanation:
Sum of ratio = 1/3 + 1/2 + 1/5
LCM = 30
Sum of ratio = (10 + 15 + 6) / 30 = 31 /30
Profit to be shared = 1581
P = 1/3 ; Q = 1/2 ; R = 1/5
Share of R :
(Total profit / sum of ratio) * R ratio
[1581 / (31/30)] * 1/5
(1581 / 1 * 30/31) * 1/5
51 * 30 * 1/5
51 * 6 = 306

mips Write a program that asks the user for an integer between 0 and 100 that represents a number of cents. Convert that number of cents to the equivalent number of quarters, dimes, nickels, and pennies. Then output the maximum number of quarters that will fit the amount, then the maximum number of dimes that will fit into what then remains, and so on.
Answer:
Explanation:
The following program was written in Java. It creates a representation of every coin and then asks the user for a number of cents. Finally, it goes dividing and calculating the remainder of the cents with every coin and saving those values into the local variables of the coins. Once that is all calculated it prints out the number of each coin that make up the cents.
import java.util.Scanner;
class changeCentsProgram {
// Initialize Value of Each Coin
final static int QUARTERS = 25;
final static int DIMES = 10;
final static int NICKELS = 5;
public static void main (String[] args) {
int cents, numQuarters,numDimes, numNickels, centsLeft;
// prompt the user for cents
Scanner in = new Scanner(System.in);
System.out.println("Enter total number of cents (positive integer): ");
cents = in.nextInt();
System.out.println();
// calculate total amount of quarter, dimes, nickels, and pennies in the change
centsLeft = cents;
numQuarters = cents/QUARTERS;
centsLeft = centsLeft % QUARTERS;
numDimes = centsLeft/DIMES;
centsLeft = centsLeft % DIMES;
numNickels = centsLeft/NICKELS;
centsLeft = centsLeft % NICKELS;
// display final amount of each coin.
System.out.print("For your total cents of " + cents);
System.out.println(" you have:");
System.out.println("Quarters: " + numQuarters);
System.out.println("Dimes: " + numDimes);
System.out.println("Nickels: " + numNickels);
System.out.println("Pennies: " + centsLeft);
System.out.println();

What is the main difference between sequential and parallel computing?
Answer:
In sequential composition, different program components execute in sequence on all processors. In parallel composition, different program components execute concurrently on different processors. In concurrent composition, different program components execute concurrently on the same processors.
The differences is that in sequential, a lot of program parts exist that help execute in stages on all given processors. While in parallel a lot of program parts execute concurrently on more than one processors.
What is the difference between parallel and sequential?Parallel computing is one where a given processes that is running do not wait for the former process to be done before it runs.
While Sequential is one where the process are said to be executed only by doing one at a time.
Therefore, the differences is that in sequential, a lot of program parts exist that help execute in stages on all given processors. While in parallel a lot of program parts execute concurrently on more than one processors.

continents on world maps (such as the one above) all the time?
The Value of Fossil Evidence
Answer:
Because the tectonic plates are moving so slowly in such small incraments that it would take a while before there was any noticable change.
Explanation:
Earth's plates are constantly moving, but we do not need to update the locations because the movement of the plates does not dramatically alter the surface of the Earth's landscape.
What are continents?Any of the numerous enormous landmasses is a continent. Up to seven geographical regions are typically recognized by convention rather than by any precise criterion.
The actions of plate movement take place closer to the Earth's crust, beneath the surface of the earth, and in the lithosphere.
The Earth's plates travel deep within the planet toward the crust, but when they intersect, the result is felt as earthquakes on the surface.
Thus, because plate movement has little impact on the terrain and positioning of the Earth's surface, it is not necessary to update the locations of continents on global maps.
