Python Coding Questions Given a list of customer orders where each order contains multiple dishes, find the pair of dishes that appear together in the highest number of orders. Example: If dishes A and B appear together in multiple orders, return the pair with the maximum co-occurrence count. Given a list containing duplicate numbers (e.g., [2, 2, 5, 7, 5]), return only the distinct elements. Using list comprehension, generate the squares of the first 10 positive integers. Expected output: [1, 4, 9, 16, 25, 36, 49, 64, 81, 100] Given a paragraph and a list of banned words, find the most frequent word that is not banned.
