Can anyone decipher these? There a bit random. Maybe binary but if there are other ways please include them.​

Answers

Answer:

Explanation:

so this is what "format" is about,   it's saying what do the ones and zeros represent.   b/c the bits can represent lots of different things ,  like letters with ascii code ,   and that's got several types.  some are 8 bits,  some are 16 bits,  the questions  you've shown are in groups of 5 which is really not a "thing" in binary,  it's always by twos,   without some type of  "frame work"  around the bits, we won't know what they represent,  if that is helping?   the important part is what is the "frame work"   that these bits are in.

all of your questions seem to have some  "art"  thing going on,  they make some kinda of binary artwork,  for what they are saying, that's not what's important.  Other than if they form  palindromes,   maybe that's what the questions are really about, how these do from palindromes, that is, they read the same backwards as forwards... I know.. why would anyone read backwards.. but a computer can do that pretty quickly,  sooo sometimes to check,  it will read  forwards and backwards.. but when there is a palindrome,  the computer is "confused"  

this is also a big big part of  "typing"  not like on a keyboard but when you program, and you say that  your variables are of a certain type,  like a char, or a string, or a double, you are specifying how many bits will be used to represent your data.  so then when you put the ones and zeros into the memory ,  ( think RAM)  then it's stored in groups of what ever size you've determined.    hmmmm   does this help?

Use Python.
Complete reverse() method that returns a new character array containing all contents in the parameter reversed.
Ex: If the input array is:
['a', 'b', 'c']
then the returned array will be:
['c', 'b', 'a']
import java.util.*;
public class LabProgram {
// This method reverses contents of input argument arr.
public static char[] reverse(char[] arr) {
/* Type your code here. */

Which operating system desktop or mobile is the best

Answers

Answer:

bing or alien ware is the best.

Answer:

Your choice, but personally, desktop is better.

Explanation:

Desktop devices have portrait orientations so content can stretch across a screen and often multiple messages or images can live comfortably in such a wide space. Mobile devices are usually used in portrait orientation (and the smaller screens mean that even in landscape mode, horizontal space is limited).

Suppose during a TCP connection between A and B, B acting as a TCP receiver, sometimes discards segments received out of sequence, but sometimes buffers them. Would the data sent by A still be delivered reliably and in-sequence at B? Explain why.

Answers

Answer:

Yes

Explanation:

We known that TCP is the connection [tex]\text{oriented}[/tex] protocol. So the TCP expects for the target host to acknowledge or to check that the [tex]\text{communication}[/tex] session has been established or not.

Also the End stations that is running reliable protocols will be working together in order to verify transmission of data so as to ensure the accuracy and the integrity of the data. Hence it is reliable and so the data can be sent A will still be delivered reliably and it is in-sequence at B.

1.

Select R.Reservation_ID, R.Trip_ID , C.Customer_Num,C.Last_Name from Reservation R, Customer C where C.Customer_Num=R.Customer_Num ORDER BY C.Last_Name

/*idea is to select the join the two tables by comparing customer_id field in two tables as it is the only field which is common and then print the desired result later ordering by last name to get the results in sorted order*/

2.

/*Here, the explaination will be similar to the first query. Choose the desired columns from the tables, and join the two tables by equating the common field

*/

3.

Select T.TRIP_NAME from TRIP T,GUIDE G,TRIPGUIDES TG where T.TRIP_ID=TG.TRIP_ID and TG.GUIDE_NUM=G.GUIDE_NUM and G.LAST_NAME='Abrams' and G.FIRST_NAME='Miles'

/*

Here,we choose three tables TRIP,GUIDE and TRIPGUIDES. Here we selected those trips where we have guides as Miles Abrms in the GUIDES table and equated Trip_id from TRIPGUIDES to TRIP.TRIP_Name so that can have the desired results

4.

Select T.TRIP_NAME

from TRIP T,TRIPGUIDES TG ,G.GUIDE

where T.TRIP_ID=TG.TRIP_ID and T.TYPE='Biking' and TG.GUIDE_NUM=G.GUIDE_NUM and G.LAST_NAME='Boyers' and G.FIRST_NAME='Rita'

/*

In the above question, we first selected the trip name from trip table. To put the condition we first make sure that all the three tables are connected properly. In order to do so, we have equated Guide_nums in guide and tripguides. and also equated trip_id in tripguides and trip. Then we equated names from guide tables and type from trip table for the desired results.

*/

5.

SELECT C.LAST_NAME , T.TRIP_NAME , T.START_LOCATION FROM CUSTOMER C, TRIP T, RESERVATION R WHERE R.TRIP_DATE='2016-07-23' AND T.TRIP_ID=R.TRIP_ID AND C.CUSTOMER_NUM=R.CUSTOMER_NUM

/*

The explaination for this one will be equivalent to the previous question where we just equated the desired columns where we equiated the desired columns in respective fields and also equated the common entities like trip ids and customer ids so that can join tables properly

*/

/*The comparison of dates in SQL depends on the format in which they are stored. In the upper case if the

dates are stored in the format as YYYY-MM-DD, then the above query mentioned will work. In case dates are stored in the form of a string then the following query will work.

SELECT C.LAST_NAME , T.TRIP_NAME , T.START_LOCATION FROM CUSTOMER C, TRIP T, RESERVATION R WHERE R.TRIP_DATE='7/23/2016' AND T.TRIP_ID=R.TRIP_ID AND C.CUSTOMER_NUM=R.CUSTOMER_NUM

Write a recursive function that returns 1 if an array of size n is in sorted order and 0 otherwise. Note: If array a stores 3, 6, 7, 7, 12, then isSorted(a, 5) should return 1 . If array b stores 3, 4, 9, 8, then isSorted(b, 4) should return 0.

Answers

Answer:

The function in C++ is as follows:

int isSorted(int ar[], int n){

if ([tex]n == 1[/tex] || [tex]n == 0[/tex]){

 return 1;}

if ([tex]ar[n - 1][/tex] < [tex]ar[n - 2][/tex]){

 return 0;}

return isSorted(ar, n - 1);}

Explanation:

This defines the function

int isSorted(int ar[], int n){

This represents the base case; n = 1 or 0 will return 1 (i.e. the array is sorted)

if ([tex]n == 1[/tex] || [tex]n == 0[/tex]){

 return 1;}

This checks if the current element is less than the previous array element; If yes, the array is not sorted

if ([tex]ar[n - 1][/tex] < [tex]ar[n - 2][/tex]){

 return 0;}

This calls the function, recursively

return isSorted(ar, n - 1);

}

You are given a sequence of n songs where the ith song is l minutes long. You want to place all of the songs on an ordered series of CDs (e.g. CD 1, CD 2, CD 3,... ,CD k) where each CD can hold m minutes. Furthermore, (1) The songs must be recorded in the given order, song 1, song 2,..., song n. (2) All songs must be included. (3) No song may be split across CDs. Your goal is to determine how to place them on the CDs as to minimize the number of CDs needed. Give the most efficient algorithm you can to find an optimal solution for this problem, prove the algorithm is correct and analyze the time complexity

Answers

Answer:

This can be done by a greedy solution. The algorithm does the following:  

Put song 1 on CD1.

For song 1, if there's space left on the present CD, then put the song on the present CD. If not, use a replacement CD.

If there are not any CDs left, output "no solution".

Explanation:  

The main thing is prove the correctness, do that by the "greedy stays ahead argument". For the primary song, the greedy solution is perfect trivially.  

Now, let the optimal solution match the greedy solution upto song i. Then, if the present CD has space and optimal solution puts song (i+1) on an equivalent CD, then the greedy and optimal match, hence greedy is not any worse than the optimal.Else, optimal puts song (i + 1) on subsequent CD. Consider an answer during which only song (i + 1) is moved to the present CD and zip else is modified. Clearly this is often another valid solution and no worse than the optimal, hence greedy is not any worse than the optimal solution during this case either. This proves the correctness of the algorithm. As for every song, there are constantly many operations to try to do, the complexity is O(n).

When implementing a 1:1 relationship, where should you place the foreign key if one side is mandatory and one side is optional? Should the foreign key be mandatory or optional?

Answers

Answer:

When implementing a 1:1 relationship, the foreign key should be placed on the optional side if one side is mandatory and one side is optional.  

When this is implemented, the foreign key should be made mandatory.

Explanation:

A foreign key (FK) is a primary key (PK) in relational databases.  It is used to establish a relationship with a table that has the same attribute with another table in the database.  A mandatory relationship exists when the foreign key depends on the parent (primary key) and cannot exist without the parent.  A one-to-one relationship exists when one row in a data table may be linked with only one row in another data table.

RecursionexerciseCOP 3502; Summer2021We have gone through many examples in the class and those examples are available in the slides and uploaded codes. Try to test those codes and modify as you wish for getting more clarification.In additiontry the following:---------------------------------------------------------------------------------------------------------------------------------------1.What would be the output of the following recursive function if we call rec2(5)

Answers

Answer:

The output is:

1 2 3 4 5

Explanation:

Given

See attachment for code segment

Required

The output of rec2(5)

From the attached code segment, we have the following:

The base case: if (x==0){ return;}

The above implies that, the recursion ends when the value of x gets reduced to 0

The recursion:

rec2(x-1); ---- This continually reduces x by 1 and passes the value to the function

printf("%d ", x); This prints the passed value of x

Hence, the output of rec2(5) is: 1 2 3 4 5

Write a program named edit_data.py that asks a person their age. Accept an int. Use a custom exception to return a message if the number entered is an int that is less than 1 or greater than 115. Create an exception that catches an error if a non int is entered.

Answers

An exception is an error that happens during the execution of a program. Exceptions are known to non-programmers as instances that do not conform to a general rule. The name "exception" in computer science has this meaning as well: It implies that the problem (the exception) doesn't occur frequently, i.e. the exception is the "exception to the rule". Exception handling is a construct in some programming languages to handle or deal with errors automatically. Many programming languages like C++, Objective-C, PHP, Java, Ruby, Python, and many others have built-in support for exception handling.

Error handling is generally resolved by saving the state of execution at the moment the error occurred and interrupting the normal flow of the program to execute a special function or piece of code, which is known as the exception handler. Depending on the kind of error ("division by zero", "file open error" and so on) which had occurred, the error handler can "fix" the problem and the programm can be continued afterwards with the previously saved data.

An error that occurs while a program is being run is an exception. Non-programmers see exceptions as examples that do not follow a general rule.

What is the programming?


In computer science, the term "exception" also has the following connotation: It signifies that the issue is an uncommon occurrence; it is the "exception to the rule." Some programming languages use the mechanism known as exception handling to deal with problems automatically. Exception handling is built into several programming languages, including C++, Objective-C, PHP, Java, Ruby, Python, and many others.

In order to manage errors, programs often save the state of execution at the time the problem occurred and interrupt their usual operation to run an exception handler, which is a particular function or section of code. Depending on the type of error that had occurred, the error handler can "correct" the issue and the application can then continue using the previously saved data.

Thus, An error that occurs while a program is being run is an exception.

In preparing for the upcoming holiday season, Fresh Toy Company (FTC) designed a new doll called The Dougie that teaches children how to dance. The fixed cost to produce the doll is $100,000. The variable cost, which includes material, labor, and shipping costs, is $34 per doll. During the holiday selling season, FTC will sell the dolls for $42 each. If FTC overproduces the dolls, the excess dolls will be sold in January through a distributor who has agreed to pay FTC $10 per doll. Demand for new toys during the holiday selling season is extremely uncertain. Forecasts are for expected sales of 60,000 dolls with a standard deviation of 15,000. The normal probability distribution is assumed to be a good description of the demand. FTC has tentatively decided to produce 60,000 units (the same as average demand), but it wants to conduct an analysis regarding this production quantity before finalizing the decision. (a) Create a what-if spreadsheet model using formulas that relate the values of production quantity, demand, sales, revenue from sales, amount of surplus, revenue from sales of surplus, total cost, and net profit. What is the profit corresponding to average demand (60,000 units)? $ (b) Modeling demand as a normal random variable with a mean of 60,000 and a standard deviation of 15,000, simulate the sales of The Dougie doll using a production quantity of 60,000 units. What is the estimate of the average profit associated with the production quantity of 60,000 dolls? $ How does this compare to the profit corresponding to the average demand (as computed in part a)? The input in the box below will not be graded, but may be reviewed and considered by your instructor (c) Before making a final decision on the production quantity, management wants an analysis of a more aggressive 70,000-unit production quantity and a more conservative 50,000-unit production quantity. Run your simulation with these two production quantities. What is the mean profit associated with each? When ordering 50,000 units, the average profit is approximately $. When ordering 70,000 units, the average profit is approximately $. (d) Besides mean profit, what other factors should FTC consider in determining a production quantity? Compare the four production quantities (40,000; 50,000; 60,000; and 70,000) using all these factors. What trade-offs occur? If required, round Probability of a Loss to three decimal places and Probability of a Shortage to two decimal places. What is your recommendation?
