Write a computer program to add three new links greedily in an N-node string topology network (see Figure 5.17(a) for a reference). Note that the greedy global decision–based link addition should optimize the average path length of the network after addition of each link. Also, there are no self-loops or parallel edges in the network (before or after new link addition).

Which of the following statements is false?
a. The following code uses a list comprehension to create a list of 600 random die values, then uses NumPy’s unique function to determine the unique roll values (guaranteed to include all six possible face values) and their frequencies: rolls = [random.randrange(1, 7) for i in range(600)] values, frequencies = np.unique(rolls, return_counts=True) b. The NumPy library provides the high-performance ndarray collection, which is typically much faster than lists. c. If you pass a list (like rolls) into np.unique, NumPy converts it to an ndarray for better performance. d. Specifying the keyword argument return_counts=True tells unique to count each unique value’s number of occurrences.
