Challenge: Given a two-dimensional array of integers, return the flattened version of the array with all the integers in the sorted (ascending) order. Example: Given [[3, 2, 1], [4, 6, 5], [], [9, 7, 8]], your function should return [1, 2, 3, 4, 5, 6, 7, 8, 9]. Solution: def flatten_and_sort(array): arr = [] for i in array: arr.extend(i) return sorted(arr) Other Solution: from itertools import c..
