I'm writing a function that returns the total number of ways a cashier can make change given the `amount` of change that the customer needs and an array of `coins` from which to create the change. My solution conceptually works but it actually does not return the results I am expecting because I cannot create a Set of Map<A, B> in JavaScript. I'm also somewhat sure that InterviewCake is expecting a less computationally expensive answer. |
