Suppose you design a banking application. The class CheckingAccount already exists and implements interface Account. Another class that implements the Account interface is CreditAccount. When the user calls creditAccount.withdraw(amount) it actually makes a loan from the bank. Now you have to write the class OverdraftCheckingAccount, that also implements Account and that provides overdraft protection, meaning that if overdraftCheckingAccount.withdraw(amount) brings the balance below 0, it will actually withdraw the difference from a CreditAccount linked to the OverdraftCheckingAccount object. What design pattern is appropriate in this case for implementing the OverdraftCheckingAccount class
Answer:
Strategy
Explanation:
The strategic design pattern is defined as the behavioral design pattern that enables the selecting of a algorithm for the runtime. Here the code receives a run-time instructions regarding the family of the algorithms to be used.
In the context, the strategic pattern is used for the application for implementing OverdraftCheckingAccount class. And the main aspect of this strategic pattern is the reusability of the code. It is behavioral pattern.
At a coffee shop, a coffee costs $1. Each coffee you purchase, earns one star. Seven stars earns a free coffee. In turn, that free coffee earns another star. Ask the user how many dollars they will spend, then output the number of coffees that will be given and output the number of stars remaining. Hint: Use a loop
Answer:
Explanation:
The following is written in Python, no loop was needed and using native python code the function is simpler and more readable.
import math
def coffee():
dollar_amount = int(input("How much money will you be using for your purchase?: "))
free_coffees = math.floor(dollar_amount / 7)
remaining_stars = dollar_amount % 7
print("Dollar Amount: " + str(dollar_amount))
print("Number of Coffees: " + str(dollar_amount + free_coffees))
print("Remaining Stars: " + str(remaining_stars))

Write a SELECT statement that returns these columns from the Orders table: The CardNumber column The length of the CardNumber column The last four digits of the CardNumber columnWhen you get that working right, add the column that follows to the result set. This is more difficult because the column requires the use of functions within functions. A column that displays the last four digits of the CardNumber column in this format: XXXX-XXXX-XXXX-1234. In other words, use Xs for the first 12 digits of the card number and actual numbers for the last four digits of the number.selectCardNumber,len(CardNumber) as CardNumberLegnth,right(CardNumber, 4) as LastFourDigits,'XXXX-XXXX-XXXX-' + right(CardNumber, 4) as FormattedNumberfrom Orders
Answer:
SELECT
CardNumber,
len(CardNumber) as CardNumberLength,
right(CardNumber, 4) as LastFourDigits,
'XXXX-XXXX-XXXX-' + right(CardNumber, 4) as FormattedNumber
from Orders
Explanation:
The question you posted contains the answer (See answer section). So, I will only help in providing an explanation
Given
Table name: Orders
Records to select: CardNumber, length of CardNumber, last 4 digits of CardNumber
From the question, we understand that the last four digits should display the first 12 digits as X while the last 4 digits are displayed.
So, the solution is as follows:
SELECT ----> This implies that the query is to perform a select operation
CardNumber, ---> This represents a column to read
len(CardNumber) as CardNumberLength, -----> len(CardNumber) means that the length of card number is to be calculated.
as CardNumberLength implies that an CardNumberLength is used as an alias to represent the calculated length
right(CardNumber, 4) as LastFourDigits, --> This reads the 4 rightmost digit of column CardNumber
'XXXX-XXXX-XXXX-' + right(CardNumber, 4) as FormattedNumber --> This concatenates the prefix XXXX-XXXX-XXXX to the 4 rightmost digit of column CardNumber
as FormattedNumber implies that an FormattedNumber is used as an alias to represent record
from Orders --> This represents the table where the record is being read.

Is there SUM in Small basic?
Answer:
no
Explanation:
Chris recently received an array p as his birthday gift from Joseph, whose elements are either 0 or 1. He wants to use it to generate an infinite long superarray. Here is his strategy: each time, he inverts his array by bits, changing all 0 to 1 and all 1 to 0 to get another array, then concatenate the original array and the inverted array together. For example, if the original array is [0,1,1,0] then the inverted array will be [1,0,0,1] and the new array will be [0,1,1,0,1,0,0,1]. He wonders what the array will look like after he repeat this many many times.
He ask you to help him sort this out. Given the original array pp of length ????n and two indices a,b (????≪????≪????, means much less than) Design an algorithm to calculate the sum of elements between a and b of the generated infinite array p^, specifically, ∑????≤????≤????p????^. He also wants you to do it real fast, so make sure your algorithm runs less than O(b) time. Explain your algorithm and analyze its complexity.

How many GPRs (General purpose registers) are in ATMEGA?
Answer:
There are 32 general-purpose 8-bit registers, RO-R31 All arithmetic and logic operations operate on those registers; only load and store instructions access RAM. A limited number of instructions operate on 16-bit register pairs.
Suppose that a computer has three types of floating point operations: add, multiply, and divide. By performing optimizations to the design, we can improve the floating point multiply performance by a factor of 10 (i.e., floating point multiply runs 10 times faster on this new machine). Similarly, we can improve the performance of floating point divide by a factor of 15 (i.e., floating point divide runs 15 times faster on this new machine). If an application consists of 50% floating point add instructions, 30% floating point multiply instructions, and 20% floating point divide instructions, what is the speedup achieved by the new machine for this application compared to the old machine
Answer:
1.84
Explanation:
Operation on old system
Add operation = 50% = 0.5
Multiply = 30% = 0.3
Divide = 20% = 0.2
T = total execution time
For add = 0.5T
For multiplication = 0.3T
For division = 0.2T
0.5T + 0.3T + 0.2T = T
For new computer
Add operation is unchanged = 0.5T
Multiply is 10 times faster = 0.3T/10 = 0.03T
Divide is 15 times faster = 0.2T/15= 0.0133T
Total time = 0.5T + 0.03T + 0.0133T
= 0.54333T
Speed up = Old time/ new time
= T/0.54333T
= 1/0.54333
= 1.84

Write a function named printPattern that takes three arguments: a character and two integers. The character is to be printed. The first integer specifies the number of times that the character is to be printed on a line (repetitions), and the second integer specifies the number of lines that are to be printed. Also, your function must return an integer indicating the number of lines multiplied by the number of repetitions. Write a program that makes use of this function. That is in the main function you must read the inputs from the user (the character, and the two integers) and then call your function to do the printing.
Answer:
import java.util.Scanner;
public class Main
{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
char c;
int n1, n2;
System.out.print("Enter the character: ");
c = input.next().charAt(0);
System.out.print("Enter the number of times that the character is to be printed on a line: ");
n1 = input.nextInt();
System.out.print("Enter the number of lines that are to be printed: ");
n2 = input.nextInt();
printPattern(c, n1, n2);
}
public static int printPattern(char c, int n1, int n2){
for (int i=0; i<n2; i++){
for (int j=0; j<n1; j++){
System.out.print(c);
}
System.out.println();
}
return n1 * n2;
}
}
Explanation:
*The code is in Java.
Create a function named printPattern that takes one character c, and two integers n1, n2 as parameters
Inside the function:
Create a nested for loop. Since n2 represents the number of lines, the outer loop needs to iterate n2 times. Since n1 represents the number of times that the character is to be printed, the inner loop iterates n1 times. Inside the inner loop, print the c. Also, to have a new line after the character is printed n1 times on a line, we need to write a print statement after the inner loop.
Return the n1 * n2
Inside the main:
Declare the variables
Ask the user to enter the values for c, n1 and n2
Call the function with these values
. Suppose an instruction takes 1/2 microsecond to execute (on the average), and a page fault takes 250 microseconds of processor time to handle plus 10 milliseconds of disk time to read in the page. (a) How many pages a second can the disk transfer? (b) Suppose that 1/3 of the pages are dirty. It takes two page transfers to replace a dirty page. Compute the average number of instructions between page fault that would cause the system to saturate the disk with page traffic, that is, for the disk to be busy all the time doing page transfers.
Answer:
a. 100.
b. 31500.
Explanation:
So, we are given the following data which is going to help in solving this particular question.
The time required to execute (on the average) = 1/2 microsecond , a page fault takes of processor time to handle = 250 microseconds and the disk time to read in the page = 10 milliseconds.
Thus, the time taken by the processor to handle the page fault = 250 microseconds / 1000 = 0.25 milliseconds.
The execution time = [ 1/2 microseconds ]/ 1000 = 0.0005 milliseconds.
The number of Pages sent in a second by the disc = 1000/10 milliseconds = 100.
Assuming U = 1.
Hence, the disc transfer time = [2/3 × 1 } + [ 1/3 × 0.25 milliseconds + 15 ] × 2.
=0.667 + 15.083.
= 15.75 millisecond.
Average number of instruction = 15.75/0.0005 = 31500.
It should be noted that the number of pages in a second will be 100 pages.
From the information given, it was stated that the instruction takes 1/2 microsecond to execute and a page fault takes 250 microseconds of processor time to handle plus 10 milliseconds of disk time to read the page.
Therefore, the execution time will be:
= 0.5/1000
= 0.0005
Therefore, the number of pages will be:
= 1000/10
= 100
Also, the disc transfer time will be;
= (2/3 × 1) + (1/3 × 0.25 + 15) × 2
= 0.667 + 15.083
= 15.75
Therefore, the average number of instructions will be:
= 15.75/0.0005
= 31500

In this exercise, you are going to build a hierarchy to create instrument objects. We are going to create part of the orchestra using three classes, Instrument, Wind, and Strings. Note that the Strings class has a name very close to the String class, so be careful with your naming convention!We need to save the following characteristics:Name and family should be saved for all instrumentsWe need to specify whether a strings instrument uses a bowWe need to specify whether a wind instrument uses a reedBuild the classes out with getters and setters for all classes. Only the superclass needs a toString and the toString should print like this:Violin is a member of the String family.Your constructors should be set up to match the objects created in the InstrumentTester class.These are the files givenpublic class InstrumentTester{public static void main(String[] args){/*** Don't Change This Tester Class!** When you are finished, this should run without error.*/Wind tuba = new Wind("Tuba", "Brass", false);Wind clarinet = new Wind("Clarinet", "Woodwind", true); Strings violin = new Strings("Violin", true);Strings harp = new Strings("Harp", false); System.out.println(tuba);System.out.println(clarinet); System.out.println(violin);System.out.println(harp);}}////////////////////////////public class Wind extends Instrument{}///////////////////////////public class Strings extends Instrument{ }/////////////////////////public class Instrument{ }
Answer:
Explanation:
The following code is written in Java and creates the classes, variables, and methods as requested.

Answer:
They are set up manually
Explanation:
BGP neighbor relationships formed "They are set up manually."
This is explained between when the BGP developed a close to a neighbor with other BGP routers, the BGP neighbor is then fully made manually with the help of TCP port 179 to connect and form the relationship between the BGP neighbor, this is then followed up through the interaction of any routing data between them.
For BGP neighbors relationship to become established it succeeds through various phases, which are:
1. Idle
2. Connect
3. Active
4. OpenSent
5. OpenConfirm
6. Established
Goal: The campus squirrels are throwing a party! Do not ask. They need you to write a method that will determine whether it will be successfull (returns true) or not (returns false). The decision will be based on int values of the two parameters "squirrels" and "walnuts" representing respectively the number of squirrels attending the party and the numbers of walnuts available to them. The rules for making that determination are detailed below. Variables declarations & initialization: Boolean variable named "result", initialized to false. Steps for the code: First, if less than 1 squirrel attends, then "result" is assigned false. Else, we consider the following conditions: If we have less than, or exactly, 10 squirrels attending: Then: If we have less than 15 walnuts, Then: "result" is set to false. Else: if we have less than, or exactly, 30 walnuts Then: "result" is set to true. Else: "result" is set to false. Else: If less than, or exactly, 30 squirrels are attending Then: If the number of walnuts is more or equal to twice the number of squirrels attending Then: "result" is set to true Else: "result" is set to false Else: If the number of walnuts is equal to 60 plus the number of squirrels attending minus 30 Then: "result" is set to true Else: "result" is set to false
Answer:
Following are the code to the given question:
#include<iostream>// header file
using namespace std;
int main()//main function
{
int squirrels, walnuts;//defining integer variable
bool result = false; //defining a bool variable that holds a false value
cout<<"Enter the number of squirrels"<<endl;//print message
cin>>squirrels; // input integer value
cout<<"Enter the number of walnuts"<<endl;//print message
cin>>walnuts; // input integer value
if(squirrels < 1)//use if variable that checks squirrels value less than 1
{
result = false;//use result variable that holds false value
}
else//defining else block
{
if(squirrels <= 10)//use if variable that checks squirrels value less than equal to 10
{
if(walnuts < 15) //use if variable that checks walnuts value less than 15
result = false;//use result variable that holds false value
else if(walnuts <= 30)//use elseif block that checks walnuts less than equal to 30
result = true; //use result variable that holds true value
else //defining else block
result = false;//use result variable that holds false value
}
else if(squirrels <= 30)//use elseif that checks squirrels value less than equal to 30
{
if(walnuts >= 2*squirrels) //use if block to check walnuts value greater than equal to 2 times of squirrels
result = true; //use result variable that holds true value
else//defining else block
result = false;//use result variable that holds false value
}
else if(walnuts == 60 + squirrels - 30)//using elseif that checks walnuts value equal to squirrels
result = true;//use result variable that holds true value
else //defining else block
result = false;//use result variable that holds false value
}
if(result)//use if to check result
cout<<"True";//print True as a message
else //defining else block
cout<<"False";//print False as a message
return 0;
}
Output:
Enter the number of squirrels
10
Enter the number of walnuts
30
True
Explanation:
In this code, two integer variable "squirrels and walnuts" and one bool variable "result" is declared, in which the integer variable use that input the value from the user-end, and inside this the multiple conditional statements is used that checks integer variable value and use the bool variable to assign value as per given condition and at the last, it uses if block to check the bool variable value and print its value.
