a) Write a program that asks user to enter number of vertices in a directed graph and then the adjacency matrix representing the directed graph. The program, then, must display the node with the highest outdegree. Assume that nodes are named as 0, 1, 2 and so on. You will find a sample run of the program below. Enter number of vertices: 4 Enter adjacency matrix: 0 1 1 1 0 0 0 0 0 0 0 0 0 1 1 0 Node with the highest outdegree: 0

Python question Analysis: Invariants (Q16-17) For each of the following functions, identify the loop invariant, exit condition and post condition. Question 16 (Invariant 1) This function returns the list of integers that are multiples of both 3 and 7 that occurs within a given list. Identify the loop exit condition, the loop post-condition, and the loop invariant at the end of the loop, which shows the algorithm’s correctness. def multiples_count(lst): """ Input: a list of integers, lst Output: the list of integers in lst that are multiples of both 3 and 7 """ res = [] for i in range(len(lst)): if lst[i]%3 == 0 and lst[i]%7 == 0: res.append(lst[i]) # Identify the loop invariant here return res Question 17 (Invariant 2) This function checks if a given list (of comparable elements) is sorted in ascending order.
