Oh No！Wrong Bus！

My list ‘all persons' is used to store the generated villains. Because the number of generated people is random, I need to use a unified method to turn everyone into a whole. 

I use a loop to generate two random sets of a specific number of person objects, and add each newly created Person to the 'allPersons' list. 

In the logic of person leaving the bus, I also used a loop to select a random number of person objects.
