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.
Answers
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.

Imagine 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 operation
Answers
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.
Write a program that rolls two dice until the user gets snake eyes. You should use a loop and a half to do this. Each round you should roll two dice (Hint: use the randint function!), and print out their values. If the values on both dice are 1, then it is called snake eyes, and you should break out of the loop. You should also use a variable to keep track of how many rolls it takes to get snake eyes.
Sample Run:
Rolled: 6 5
Rolled: 5 2
Rolled: 3 6
Rolled: 6 2
Rolled: 1 2
Rolled: 5 3
Rolled: 1 4
Rolled: 1 1
It took you 8 rolls to get snake eyes.
I have most of the code but when it prints it say you rolled 0 times every time.
import random
# Enter your code here
num_rolls = 0
import random
# Enter your code here
while True:
roll_one = random.randint(1,6)
roll_two = random.randint(1,6)
print ("Rolled: " +str(roll_one) +"," + str(roll_two))
if (roll_one == 1 and roll_two == 1):
print ("it took you " + str(num_rolls) + " rolls")
break
output:
Rolled: 3,5
Rolled: 6,4
Rolled: 2,4
Rolled: 3,6
Rolled: 5,2
Rolled: 1,1
it took you 0 rolls
suppose to say:
It took you (however many rolls) not 0
Answers
import random
num_rolls = 0
while True:
r1 = random.randint(1, 6)
r2 = random.randint(1, 6)
print("Rolled: " + str(r1) + "," + str(r2))
num_rolls += 1
if r1 == r2 == 1:
break
print("It took you "+str(num_rolls)+" rolls")
I added the working code. You don't appear to be adding to num_rolls at all. I wrote my code in python 3.8. I hope this helps.
The program uses loops and conditional statements.
Loops perform repetitive operations, while conditional statements are statements used to make decisions
The program in Python where comments are used to explain each line is as follows:
#This imports the random module
import random
#This initializes the number of rolls to 0
num_rolls = 0
#The following loop is repeated until both rolls are 1
while True:
#This simulates roll 1
roll_one = random.randint(1,6)
#This simulates roll 2
roll_two = random.randint(1,6)
#This prints the outcome of each roll
print ("Rolled: " +str(roll_one) +"," + str(roll_two))
#This counts the number of rolls
num_rolls+=1
#When both rolls are the 1
if (roll_one == 1 and roll_two == 1):
#This exits the loop
break
#This prints the number of rolls
print ("it took you " + str(num_rolls) + " rolls")

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
Answers
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;

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.

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

What is the time complexity foreach of the three key operations
Answers
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) ).

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.

Cloud computing can be defined as a type of computing that requires shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives.
Generally, cloud computing offers individuals and businesses a fast, effective and efficient way of providing services.
Cloud computing comprises of three (3) service models and these are;
1. Platform as a Service (PaaS).
2. Software as a Service (SaaS).
3. Infrastructure as a Service (IaaS).
An Infrastructure as a service (IaaS) provides virtualized computing resources for end users over the internet. For example, the provisioning of On-demand computing resources such as storage, network, virtual machines (VMs) etc., so as to enable the end users install various software applications or programs, database and servers.
Hence, the cloud service model in which virtual machines are provisioned is IaaS.
Output values below an amount
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.

while numC > 3:
numC = numC / 2
numC =
The initial numC value = 12
Condition : while numC is greater than 3 ; 12 > 3 (condition met)
The expression numC / 2 is evaluated
numC / 2 = 12 / 2 = 6
numC then becomes 6 ;
Condition : while numC is greater than 3 ; 6 > 3 (condition met)
numC / 2 = 6 /2 = 3
numC = 3
Condition : while numC is greater than 3 ; 3 > 3 (condition not met)
Loop terminates
numC = 3
