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'] NOTE: Because sets are unordered, they are printed using the sorted() function here for comparison.

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
