Given a partial main.py and PlaneQueue class in PlaneQueue.py, write the push() and pop() instance methods for PlaneQueue. Then complete main.py to read in whether flights are arriving or have landed at an airport.

An "arriving" flight is pushed onto the queue.
A "landed" flight is popped from the front of the queue.
Output the queue after each plane is pushed or popped. Entering -1 exits the program.

Click the orange triangle next to "Current file:" at the top of the editing window to view or edit the other files.

Note: Do not edit any existing code in the files. Type your code in the TODO sections of the files only. Modifying any existing code may result in failing the auto-graded tests.

Important Coding Guidelines:

Use comments, and whitespaces around operators and assignments.
Use line breaks and indent your code.
Use naming conventions for variables, functions, methods, and more. This makes it easier to understand the code.
Write simple code and do not over complicate the logic. Code exhibits simplicity when it’s well organized, logically minimal, and easily readable.
Ex: If the input is:

arriving AA213
arriving DAL23
arriving UA628
landed
-1
the output is:

Air-traffic control queue
Next to land: AA213

Air-traffic control queue
Next to land: AA213
Arriving flights:
DAL23

Air-traffic control queue
Next to land: AA213
Arriving flights:
DAL23
UA628

AA213 has landed.
Air-traffic control queue
Next to land: DAL23
Arriving flights:
UA628
code:
from PlaneQueue import PlaneQueue
from PlaneNode import PlaneNode

if __name__ == "__main__":
plane_queue = PlaneQueue()

# TODO: Read in arriving flight codes and whether a flight has landed.
# Print the queue after every push() or pop() operation. If the user
# entered "landed", print which flight has landed. Continue until -1
# is read.

Based on your instructions, I assume the array containing the valid names for 10 cities in Michigan is named michigan_cities, and the user input for the city name is stored in a string variable named city_name.

#include <iostream>

#include <string>

int main() {

   std::string michigan_cities[10] = {"Ann Arbor", "Detroit", "Flint", "Grand Rapids", "Kalamazoo", "Lansing", "Muskegon", "Saginaw", "Traverse City", "Warren"};

   std::string city_name;

   bool found = false;  // flag variable to indicate if a match is found

   std::cout << "Enter a city name: ";

   std::getline(std::cin, city_name);

   for (int i = 0; i < 10; i++) {

       if (city_name == michigan_cities[i]) {

           found = true;

           break;

       }

   }

   if (found) {

       std::cout << city_name << " is a city in Michigan." << std::endl;

   } else {

       std::cout << city_name << " is not a city in Michigan." << std::endl;

   }

   return 0;

}

In the loop, we compare each element of the michigan_cities array with the user input city_name using the equality operator ==. If a match is found, we set the found flag to true and break out of the loop.

After the loop, we use the flag variable to determine whether the city name was found in the array. If it was found, we print a message saying so. If it was not found, we print a message saying it's not a city in Michigan.

When the program is executed with the given input, the output should be:

Enter a city name: Chicago

Chicago is not a city in Michigan.

Enter a city name: Brooklyn

Brooklyn is not a city in Michigan.

Enter a city name: Watervliet

Watervliet is a city in Michigan.

"The Future Doesn't Need Us" is an essay by computer scientist and author Bill Joy, published in 2000 in Wired magazine. In the essay, Joy expresses his concern about the potential dangers of emerging technologies such as nanotechnology, robotics, and artificial intelligence.

Joy argues that while these technologies have the potential to solve many of the world's problems, they also pose significant risks, such as the possibility of self-replicating machines that could cause widespread destruction. Joy suggests that these risks may outweigh the benefits, and that we should proceed with caution when developing these technologies.

Joy also expresses concern about the potential loss of human control over technology. He argues that as machines become more advanced and intelligent, they may become capable of making decisions without human input, leading to a loss of control over our own creations.

Overall, Joy's essay suggests that we need to carefully consider the implications of emerging technologies, and that we should not blindly pursue technological progress without considering the potential risks and consequences.
