. List Comprehensions: Write a List Comprehensions for the following: Given a list of words 'words', write a list comprehension that compares the first and last character of each a word and creates a new list with the smallest character in each element (you may assume all words are lowercase). For example: words = ['sandbox', 'portabello','lion', 'australia', 'salamander'] should give you ['s','o','1','a', 'r'] Given an adjacency matrix (list of lists) 'm', write a list comprehension that looks for a vertex 'i' and produces a list of all of its neighbours. For example: [[0,1,1,0], [1,0,1,1], [1,1,0,0], [0,1,0,0]] If i = 0, your list comprehension should return [1,2] If i = 1, your list comprehension should return [0,2,3] m
