Consider a dictionary that maps integers to other integers. Each key within the dictionary has a value which could or could not be another key within the dictionary. We can “walk” through this dictionary by taking a key’s value and using that value as the next key to check until either we return to a key we previously visited or we reach a key that doesn’t exist within the dictionary. If we find a key which eventually gets back to a previously seen key, we call this a cycle. Implement the function has_cycle function, which takes in this dictionary format and checks if there are any cycles within the dictionary. If there is, return True. Otherwise, return False. {0: 1, 1: 2, 2: 1, 4: 5} should return True as 0 goes to 1, goes to 2, 2 goes back to 1. {0: 1, 1: 2, 2: 3, 8: 0} should return False as there are no keys which eventually revisit a seen key. {0: 1, 1: 2, 2: 3, 4: 4} should return True as 4 goes to itself. {} doesn’t have anything, so it always should be False.
