Given this Hasse diagram, which of the following statements is false? d b g d and a are comparable. a and f are incomparable. d is the only maximal element. a and f are minimal elements.

Discuss the repetition constructs. Give an illustrative example for each one of them.

Using C++  Please add the specific explanation. Thanks. Huffman coding is used to compress data. The idea is straightforward: represent more commonlonger strings with shorter ones via a basic translation matrix. The translation matrix is easilycomputed from the data itself by counting and sorting by frequency.For example, in a well-known corpus used in Natural Language Processing called the "Brown"corpus (see nltk.org), the top-20 most frequent tokens, which are words or punctuation marksare listed below associated with frequency and code. The word "and" for example requireswriting three characters. However, if I encoded it differently, say, using the word "5" (yes, Icalled "5" a word on purpose), then I save having to write two extra characters! Note, the word"and" is so frequent, I save those two extra characters many times over!Token Frequency Codethe 62713 1, 58334 2. 49346 3of 36080 4and 27932 5to 25732 6a 21881 7in 19536 8that 10237 9is 10011 10was 9777 11for 8841 12`` 8837 13''…

Write a procedure called STRUCTURE-TO-MATRIX that takes an adjacency structure as its only parameter, and returns an equivalent adjacency matrix. Assume there is a procedure MAKE-MATRIX(m, n) that returns an m × n integer matrix, where m ≥ 0 and n ≥ 0. The integers in this matrix are undefined.

PLEASE help with part A,B, AND C(which is like part c and d because theres two parts to C)! Please if possible, give an explanation along with the solution so I can understand why the answer is what it is.

C PROGRAMMING Implement dijkstras alorithm  Check that the Graph graph, and starting node, id, are valid• Create the set S containing all the networks (vertices) except the source node (you might wantto use an array for this.• Create an array to represent the table D and initialise it with the weights of the edges from thesource node, or infinity if no edge exists. You should use the constant DBL_MAX to representinfinity.• Create an array to represent the table R and initialise it with the next hops if an edge existsfrom the source, or 0 otherwise.• Then repeatedly follow the remaining rules of Dijkstra’s algorithm, updating the values in D andR until S is empty.• Each of the values required to complete the above can be found by calling the variousfunctions (get_vertices(), get_edge(), edge_destination(), edge_weight(), etc.)in the supplied graph library.• Once Dijkstra’s algorithm has run, you will need to create the routing table to be returned byallocating enough memory for the…

(a)  Give a regular expression that describes all strings accepted by the automaton. (b)  Use a subset construction to construct DFA that accepts the same language. Clearly specify the transition table and the start and accepting states. (c) Explain concisely how you can use reachability in the graph to reduce the number of states as much as possible. You might need to draw the unreduced DFA first (for yourself, no need to submit) to better see what is going on. How many states do you end up with? Draw the resulting DFA (with the reduced number of states).

1) why is it a good idea to separate the first (entry) node from any looping nodes? and (2) why is it a good idea to have JUST ONE alternative direction, given an operation? [For instance if X < Y we go from node 3 to node 4 ONLY and no other node]. And, (3) Is there a better way to do all of this? A better way to represent logic flow than these types of diagrams (either the manual ones like we used in chapter 6 or the ones we saw from the Node Generator for instance)???

If f:A->B and g:B->C, does there exist a function h:B->A such that f•k=g (composition)?

I need a reference page for this question that was answered below. What is the difference between a singly-linked list and a doubly-linked list? In what situation would you use a singly-linked list over a doubly-linked list? In what situation would you use a doubly-linked list over a singly-linked list?   If a node is in a linked list with N nodes, how many nodes will be traversed during a search for the node? Explain the best- and worst-case search scenarios. Explain why a singly-linked list defines a RemoveAfter() function, while a doubly-linked list defines a Remove() function. Could a RemoveAfter() function also be defined for a doubly-linked list? Explain why or why not. Could a Remove() function also be defined for a singly-linked list? Explain why or why not.
