The following program includes 10 cities that two people have visited. Write a program that creates:
1. A set all cities that contains all of the cities both people have visited.
2. A set same_cities that contains only cities found in both person1_cities and person2_cities.
3. A set different_cities that contains only cities found in only person1_cities or person2_cities.
Sample output for all cities:
['Accra', 'Anaheim', 'Bangkok', 'Bend', 'Boise', 'Buenos Aires', 'Cairo', 'Edmonton', 'Lima',
'London', 'Memphis', 'Orlando', 'Paris', 'Seoul', 'Tokyo', 'Vancouver', 'Zurich']

Expert Solution
Algorithm

1.  Create two sets person1_cities and person2_cities
2.  Create a set all_cities by combining person1_cities and person2_cities using the union() method
3.  Create a set same_cities by finding common elements between person1_cities and person2_cities using the intersection() method
4.  Create a set different_cities by finding the difference between person1_cities and person2_cities using the difference() method
5.  Sort all_cities, same_cities, and different_cities
6.  Print all_cities, same_cities, and different_cities
