Functions

A list is sorted in ascending order if it is empty or each item except the last one is less than or equal to its successor. Define a function isSorted that expects a list as an argument and returns True if the list is sorted, or returns False otherwise. (Hint : For a list of length 2 or greater, loop through the list and compare pairs of items, from left to right, and return False if the first item in a pair is greater.)
