Suppose that in a 00-11 knapsack problem, the order of the items when sorted by increasing weight is the same as their order when sorted by decreasing value. Give an efficient algorithm to find an optimal solution to this variant of the knapsack problem, and argue that your algorithm is correct.
Answer:
Following are the response to the given question:
Explanation:
The glamorous objective is to examine the items (as being the most valuable and "cheapest" items are chosen) while no item is selectable - in other words, the loading can be reached.
Assume that such a strategy also isn't optimum, this is that there is the set of items not including one of the selfish strategy items (say, i-th item), but instead a heavy, less valuable item j, with j > i and is optimal.
As [tex]W_i < w_j[/tex], the i-th item may be substituted by the j-th item, as well as the overall load is still sustainable. Moreover, because [tex]v_i>v_j[/tex] and this strategy is better, our total profit has dropped. Contradiction.

why absolute reference is used in spreadsheet
Absolute reference is used especially to keep the value or content of a column or row constant.
Explanation:Cell referencing is one common and important concept in spreadsheets. A cell reference or cell address is a value, mostly alphanumeric, used to identify a specific cell or cell range in a worksheet.
In spreadsheets such as that of Microsoft - excel - there are basically two types of referencing.
i. relative referencing
ii. absolute referencing
iii. mixed referencing
Relative reference is the default cell reference. When a relative reference is copied and pasted across multiple cells, it changes depending on its relative position. This type of reference is especially useful when there is a need to apply same formula across multiple rows or columns.
Absolute reference, on the other hand, will not change even though it is copied across multiple cells. It is used especially to keep the value or content of a column or row constant.
Mixed reference is a hybrid of the relative and absolute references.
Given the declaration: char a[] = "Hello"; char *p = a, *q; what operations are valid syntactically? Select all that apply. Group of answer choices q = &&a[0]; q = &&a; *q = *(&a[0]); q = &(*p);
Answer:
The valid operations are:
*q = *(&a[0]); and q = &(*p);
Explanation:
Given
The above declarations
Required
The valid operations
*q = *(&a[0]); and q = &(*p); are valid assignment operations.
However, q = &&a[0]; q = &&a; are invalid because:
The assignment operations intend to implicitly cast the char array a to pointer q. C++ does not allow such operation.
Hence, *q = *(&a[0]); and q = &(*p); are valid
Another way to know the valid operations is to run the program and look out for the syntax errors thrown by the C++ compiler

When an item is gray that means...
A. The item only works with another application
B. The item has been selected
C. The item is unavailable
D. The item has been deleted
A,B,C,orD, can anyone please help?
Answer:
B. The item has been selected
Answer:
C
Explanation:
When an item is unavailable, usually referring to the Technology field, it is gray. Gray items are things that are not created anymore, sold out or not enough supply. The color gray is usually used to symbol something bad, and not having a product is considered bad. Using our background knowledge, we can concude that the answer is option C.

Write a C++ program to accept a 5 digit integer and to validate the input based on the following rules.
Rules
1) The input number is divisible by 2. 2) The sum of the first two digits is less than last two digits. if the input number satisfies all the rules, the system prints valid and invalid, otherwise,
Example 1:
Enter a value: 11222
Output: Input number is valid
Example 2:
Enter a value: 1234
Output: Input number is invalid
Answer:
#include <iostream>
#include <string>
#include <regex>
using namespace std;
int main()
{
cout << "Enter a 5-digit number: ";
string number;
cin >> number;
bool valid = regex_search(number, regex("^\\d{4}[02468]$"));
if (valid) {
valid = stoi(number.substr(0, 1)) + stoi(number.substr(1, 1))
< stoi(number.substr(3, 1)) + stoi(number.substr(4, 1));
}
cout << number << (valid ? " is valid" : " is invalid");
}
Explanation:
Regular expressions can do all of your checking except for the sum of digits check. The checks are i.m.o. easiest if you don't treat the input as a number, but as a string with digits in it.
The regex means:
^ start of string
\d{4} exactly 4 digits
[02468] one of 0, 2, 4, 6 or 8 (this is what makes it even)
$ end of string

Explanation:
Consider the following class, which uses the instance variable balance to represent a bank account balance.
public class BankAccount {
private double balance;
public double deposit(double amount) {
/* missing code */
}
}
The deposit method is intended to increase the account balance by the deposit amount and then return the updated balance. Which of the following code segments should replace /* missing code */ so that the deposit method will work as intended?
a.
amount = balance + amount;
return amount;
b.
balance = amount;
return amount;
c.
balance = amount;
return balance;
d.
balance = amount;, , return balance;,
balance = balance + amount;
return amount;
e.
balance = balance + amount;
return balance;
Answer:
e.
balance = balance + amount;
return balance;
Explanation:
Required
Code to update account balance and return the updated balance
The code that does this task is (e).
Assume the following:
[tex]balance = 5000; amount = 2000;[/tex]
So, code (e) is as follows:
balance = balance + amount; [tex]\to[/tex]
[tex]balance = 5000 + 2000[/tex] [tex]\to[/tex]
[tex]balance = 7000[/tex]
Here, the updated value of balance is 7000
So: return balance
will return 7000 as the updated account balance
Other options are incorrect
Horizontal Navigation List Styles
Go to the Horizontal Navigation List Styles section. Karen has added a second navigation list that she wants to display horizontally. For all list items within the horizontal navigation list, create a style rule that displays the items as blocks with a width of 12.5% floated on the left margin.
Here is my code:
/* Horizontal Navigation List Styles */
.horizontal li {
display: block;
width: 12.5%;
float: left;
}
It's coming through as just a line and I have no idea how to fix it, please help!
Answer:
Explanation:
The best way to do this would be to use the following line of code
clear: left;
This would make sure that there are no floating elements (li's in this scenario) on the left side of each element. Which in this navigation list would be each individual element, causing it to move each element underneath the previous element. Therefore the entire CSS code would be
.horizontal li {
display: block;
width: 12.5%;
float: left;
clear: left;
}
An example can be seen in the attached picture below.

High-level modulation is used: when the intelligence signal is added to the carrier at the last possible point before the transmitting antenna. in high-power applications such as standard radio broadcasting. when the transmitter must be made as power efficient as possible. all of the above.
Answer:
Option d (all of the above) is the correct answer.
Explanation:
Such High-level modulation has been provided whenever the manipulation or modification of intensity would be performed to something like a radio-frequency amplifier.Throughout the very last phase of transmitting, this then generates an AM waveform having relatively high speeds or velocity.Thus the above is the correct answer.
write short notes about monitor printer and speaker
Answer:
A computer monitor is an electronic device that shows pictures for computers. Monitors often look similar to televisions. The main difference between a monitor and a television is that a monitor does not have a television tuner to change channels. Monitors often have higher display resolution than televisions.
A printer is a device that accepts text and graphic output from a computer and transfers the information to paper, usually to standard size sheets of paper. Printers vary in size, speed, sophistication, and cost. In general, more expensive printers are used for higher-resolution color printing.
Speakers receive audio input from the computer's sound card and produce audio output in the form of sound waves. Most computer speakers are active speakers, meaning they have an internal amplifier which allows you to increase the volume, or amplitude, of the sound.
A buffer is filled over a single input channel and emptied by a single channel with a capacity of 64 kbps. Measurements are taken in the steady state for this system with the following results:
Average packet waiting time in the buffer = 0.05 seconds
Average number of packets in residence = 1 packet
Average packet length = 1000 bits
The distributions of the arrival and service processes are unknown and cannot be assumed to be exponential.
Required:
What are the average arrival rate λ in units of packets/second and the average number of packets w waiting to be serviced in the buffer?
Answer:
a) 15.24 kbps
b) 762 bits
Explanation:
Using little law
a) Determine the average arrival rate ( λ ) in units of packets/s
λ = r / Tr --- 1
where ; r = 1000 bits , Tr = Tw + Ts = 0.05 + (( 1000 / (64 * 1000 )) = 0.0656
back to equation 1
λ = 1000 / 0.0656 = 15243.9 = 15.24 kbps
b) Determine average number of packets w to be served
w = λ * Tw = 15243.9 * 0.05 = 762.195 ≈ 762 bits
