Answer:
Create a dynamic-sized circularly-linked list to hold a tuple of the adverts and the count. As the program runs, the sum of the counts is used to calculate the fixed advertisement time which is saved in a variable time_slot. Then a loop statement should be used to traversal the linked list continuously until the count sum is exhausted for the day.
Explanation:
A circularly-linked list is a linked list with both ends joined together. With this data structure, the continuous traversal of the list is easier and faster. A conditional statement is used in the algorithm to check and decrement the count of each advert and when all is zero or false, the program ends.
