I'm running a 5-star restaurant and I can only have the best items on my menu. My menu offers 6 items, each represented by a number from 1-6. If an item on my menu does not sell or does not sell that much compared to others, I must act and replace it with something that sells! Identify which dishes do not sell. If every dish sells, print the set of dishes that were ordered least. Input: A single line containing the dish number that were ordered. Treat as one number. INPUT: 156356231 Output: The list of dishes not ordered in numerical order. If every dish sells, print the set of dishes that were ordered least. Separate each number with a new line. OUTPUT: 4

ONLY IF STATEMENTS ALLOWED!!!! NO RANGE FUNCTION, NO SETS, NO LISTS, NO LOOPS, ETC Angela loves reading books. She recently started reading an AI generated series called “Harry Trotter”. Angela is collecting books from the series at her nearest bookstore. Since the series is AI generated, the publishers have produced an infinite collection of the books where each book is identified by a unique integer. The bookstore has exactly one copy of each book. Angela wants to buy the books in the range [l,r], where l ≤ r. As an example, the range [−3,3] means that Angela wants to buy the books − 3, − 2, − 1, 0, 1, 2, and 3. Dan also loves the series (or maybe annoying Angela – who knows, really), and he manages to sneak into the bookstore very early to buy all of the books in the range [d,u], where d ≤ u. When Angela later visits, sadly she will not find those books there anymore. For example, if Angela tries to buy books [−2,3] and Dan has bought books [0,2], Angela would only receive books…
