Suppose that each country completely specializes in the production of the good in which it has a comparative advantage, producing only that good. In
this case, the country that produces rye will produce million bushels per week, and the country that produces jeans will produce
million pairs per week.
Answer:
In this case, the country that produces rye will produce 24 million bushels per week, and the country that produces jeans will produce 64 million pairs per week.
Explanation:
Total labor hour = 4 million hour
Number of bushes produce in 1 hour = 6
⇒total bushes produce = 6*4 = 24 million
∴ we get
The country that produces rye will produce 24 million bushels per week
Now,
Total labor hour = 4 million hour
Number of pairs produce in 1 hour = 16
⇒total bushes produce = 16*4 = 64 million
∴ we get
The country that produces jeans will produce 64 million pairs per week.

Write a program named BinaryToDecimal.java that reads a 4-bit binary number from the keyboard as a string and then converts it into decimal. For example, if the input is 1100, the output should be 12. (Hint: break the string into substrings and then convert each substring to a value for a single bit. If the bits are b0, b1, b2, b3, then decimal equivalent is 8b0 4b1 2b2 b3)
Answer:
import java.util.*;
public class BinaryToDecimal
{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String binaryNumber;
int decimalNumber = 0;
System.out.print("Enter the binary number: ");
binaryNumber = input.nextLine();
for(int i=0; i<binaryNumber.length(); i++){
char c = binaryNumber.charAt(binaryNumber.length()-1-i);
int digit = Character.getNumericValue(c);
decimalNumber += (digit * Math.pow(2, i));
}
System.out.println(decimalNumber);
}
}
Explanation:
Create a Scanner object to be able to get input from the user
Declare the variables
Ask the user to enter the binaryNumber as a String
Create a for loop that iterates through the binaryNumber. Get each character using charAt() method. Convert that character to an integer value using Character.getNumericValue(). Add the multiplication of integer value and 2 to the power of i to the decimalNumber variable (cumulative sum)
When the loop is done, print the decimalNumber variable
A year with 366 days is called a leap year. Leap years are necessary to keep the calendar in sync with the sun, because the earth revolves around the sun once very 365.25 days. As a result, years that are divisible by 4, like 1996, are leap years. However, years that are divisible by 100, like 1900, are not leap years. But years that are divisible by 400, like 2000, are leap years. Write a program named leap_year.py that asks the user for a year and computes whether that year is a leap year.
Answer:
Follows are the code to this question:
y = int(input("Enter a year: "))#input year value
if((y%4==0) and (y%100==0) or y%400==0):#defining if block for check leap year condition
print("Given year {0}, is a leap year".format(y))#print value
else:#else block
print("Given year {0}, is not a leap year".format(y))#print value
Output:
Enter a year: 1989
Given year 1989, is not a leap year
Explanation:
In the python code, the y variable uses the input method for input the value from the user-end. In the next step, if a conditional block is used, that's checks the leap-year condition. if the condition is true it will print leap year value with the message, otherwise, it will go to else block that prints not a leap year message.

magine that you are designing an application where you need to perform the operations Insert, DeleteMaximum, and Delete Minimum. For this application, the cost of inserting is not important, because itcan be done off-line prior to startup of the time-critical section, but the performance of the two deletionoperations are critical. Repeated deletions of either kind must work as fast as possible. Suggest a datastructure that can support this application, and justify your suggestion. What is the time complexity foreach of the three key operations
Answer:
Use the stack data structure with both best-case and worst-case time complexity of O(1) for insertion and deletion of elements.
Explanation:
The stack data structure is used in programs to hold data for which the last data in the stack is always popped out first when retrieving the data sequentially, that it, first-in, last-out.
The elements in the stack are located in an index location, which means that they can be retrieved directly by choice with constant time complexity of 1 or O(1) for best and worst-case.
So inserting, and deleting the minimum and maximum elements in the stack data structure executes at a speed of the constant 1 (big-O notation, O(1) ).

Which of the following code segments would correctly set the first two elements of array arr to 10 so that the new value of array arr will be {10, 10, 3, 4, 5} ?
a. arr[0] = 10;
arr[1] = 10;
b. arr[1] = 10;
arr[2] = 10;
c. arr[0, 1] = 10;
d. arr[1, 2] = 10;
e. arr = 10, 10, 3, 4, 5;
Answer:
A.)
arr[0] = 10;
arr[1] = 10;
Explanation:
Given the array:
arr = {1,2,3,4,5}
To set the first two elements of array arr to 10.
Kindly note that ; index numbering if array elements starts from 0
First element of the array has an index of 0
2nd element of the array has an index of 1 and so on.
Array elements can be called one at a time using the array name followed by the index number of the array enclosed in square brackets.
arr[0] = 10 (this assigns a value of 10 to the index value, which replace 1
arr[1] = 10 (assigns a value of 10 to the 2nd value in arr, which replaces 2
g n this program, you will prompt the user for three numbers. You need to check and make sure that all numbers are equal to or greater than 0 (can use an if or if/else statement for this). You will then multiply the last two digits together, and add the result to the first number. The program should then start over, once again asking for another three numbers. This program should loop indefinitely in this way. If the user enters a number lower than 0, remind the user that they need to enter a number greater than or equal to 0 and loop the program again.
Answer:
In Python:
loop = True
while(loop):
nm1 = float(input("Number 1: "))
nm2 = float(input("Number 2: "))
nm3 = float(input("Number 3: "))
if (nm1 >= 0 and nm2 >= 0 and nm3 >= 0):
result = nm2 * nm3 + nm1
print("Result: "+str(result))
loop = True
else:
print("All inputs must be greater than or equal to 0")
loop = True
Explanation:
First, we set the loop to True (a boolean variable)
loop = True
This while loop iterates, indefinitely
while(loop):
The next three lines prompt user for three numbers
nm1 = float(input("Number 1: "))
nm2 = float(input("Number 2: "))
nm3 = float(input("Number 3: "))
The following if condition checks if all of the numbers are greater than or equal to 0
if (nm1 >= 0 and nm2 >= 0 and nm3 >= 0):
If yes, the result is calculated
result = nm2 * nm3 + nm1
... and printed
print("Result: "+str(result))
The loop is then set to true
loop = True
else:
If otherwise, the user is prompted to enter valid inputs
print("All inputs must be greater than or equal to 0")
The loop is then set to true
loop = True

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, which indicates a threshold. Output all integers less than or equal to that last threshold value.
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.
Answer:
Explanation:
The following code is written in Python and it is a function called filter, which takes in the requested inputs. It then places the threshold in its own variable and pops it out of the array of inputs. Then it loops through the array comparing each element with the threshold and printing out all of the ones that are less than or equal to the threshold.
def filter():
num_of_elements = input("Enter a number: ")
count = 0
arr_of_nums = []
while count <= int(num_of_elements):
arr_of_nums.append(input("Enter a number: "))
count += 1
threshold = arr_of_nums[-1]
arr_of_nums.pop(-1)
print(threshold)
for element in arr_of_nums:
if int(element) < int(threshold):
print(element)
else:

In Cloud9, create a new file called function.cpp. If you aren't sure how to create a new .cpp file in the Cloud9 environment, refer Slide 24 of the Cloud9SetUpSlides (Links to an external site.). In this new file write a function called swapInts that swaps (interchanges) the values of two integers that it is given access to via pointer parameters. Write a main function that asks the user for two integer values, stores them in variables num1 and num2, calls the swap function to swap the values of num1
Answer:
#include <iostream>
using namespace std;
void swapInts(int* x, int* y) {
*x = *x + *y;
*y= *x - *y;
*x = *x - *y;
}
int main(){
int num1, num2;
cout << "Before swap:";
cin>>num1; cin>>num2;
swapInts(&num1, &num2);
cout<<"After swap:"<<num1<<" "<<num2;
}
Explanation:
The function begins here:
This line defines the function
void swapInts(int* x, int* y) {
The next three line swap the integer values
*x = *x + *y;
*y= *x - *y;
*x = *x - *y;
}
The main begins here:
int main(){
This line declares two integer variables
int num1, num2;
This line prompts the user for inputs before swap
cout << "Before swap:";
This line gets user inputs for both integers
cin>>num1; cin>>num2;
This line calls the function
swapInts(&num1, &num2);
This prints the numbers after swap
cout<<"After swap:"<<num1<<" "<<num2;

When dealing with Java syntax you always need to initialize an ArrayList object with its constructor. From the options listed the only correct option would be B: new ArrayList(). This would correctly initialize the ArrayList object but is not necessarily the recommended way of doing this. The truly recommended way would be the following
ArrayList<Thing> a = new ArrayList<Thing>()
ArrayLists are simply resizable array.
The statement that can replace the missing code is (b) new ArrayList();The statements that can replace the missing code is (c) I and III onlyThe syntax to create an ArrayList is:
ArrayList<Type> str = new ArrayList<Type>();
Another possible syntax is:
ArrayList var_name= new ArrayList();

What is the time complexity foreach of the three key operation
Answer:
A stack data structure should be used. The time complexity of the insert, delete minimum and maximum operation is O(1).
Explanation:
The stack data structure is an indexed structure that holds data in an easily retrievable way. Data is held in a first-in last-out method as elements in the structure are popped out from the end of the stack when retrieved sequentially.
The worst-case time complexity of getting the minimum and maximum elements in a stack and deleting it is O(1), this is also true for inserting elements in the stack data structure.
