A bag is a very similar construct to a set except that duplicates are allowed in a bag. What changes would have to be made toextend a TreeSet to create an implementation of a bag?
What will be an ideal response?
The primary change would be to remove the duplicate restriction in the add method. Since the addAll method, and then indirectly the union method, use the add method, this one change will allow duplicates. The definitions of other methods would need to be examined as well. For example, should the remove method delete the first occurrence of an element or all occurences of an element?

Use the similarity matrix in Table 8.1 to perform single and complete link hierarchical clustering. Show your results by drawing a dendrogram. The dendrogram should clearly show the order in which the points are merged.
(b) Do both sets of centroids represent stable solutions; i.e., if the K-means
algorithm was run on this set of points using the given centroids as the
starting centroids, would there be any change in the clusters generated?
(c) What are the two clusters produced by single link?
(d) Which technique, K-means or single link, seems to produce the “most
natural” clustering in this situation? (For K-means, take the clustering
with the lowest squared error.)
(e) What definition(s) of clustering does this natural clustering correspond
to? (Well-separated, center-based, contiguous, or density.)
(f) What well-known characteristic of the K-means algorithm explains the
previous behavior?

What is the “two-deep” rule relative to optical networking?
a. The horizontal distribution to the work floor can have only two 8P8C connections. b. The horizontal distribution to the work floor can have only two ST connections to the fiber patch panel. c. This is no longer an issue with high-speed single-mode fiber and wave division multiplexing equipment. d. A building should have only the main distribution and the intermediate distribution that feeds the horizontal distribution to the work area.
