A supper market has long checkout lines and the customers are not happy as the lines are blocking movement of other customers. And it's getting dangerous when the customers are constantly moving from a longer line to a shorter line. The owner intends to put physical barriers for each checkout line, but he does not know how long each barrier would be, i.e. how many customers can be accommodated by each barrier. He can gave you a list of two week-long of actual times it take to check out a customer, and the rates of which the customers arrived at the checkout area. Describe which data structure you would use to simulate this problem and solve it to give the owner a good barrier length. Justify your answer in details.
