1. The notation for the cardinality (number of elements) of a set is |A|. For example, for set A = {a,b,c} we can write: |A| = 3 because A has 3 elements. Determine the cardinality of the following sets and explain how you got it: 1. A=(3, 4, 5, 17} 2. B = {n is an Integer | 4 <= n <= 196} 3. C = (n = 2k with k Integer | 0 <= n <= 100} 4. Suppose |X| = 5, |Y| = 5 and IX n Y| = 7, what is IX U YI? 5. Suppose IX = 8, Y| = 6 and IX n Y| = 6, what is IX U YI?

In the following problems ((f) - (j)) you are given the description of a set. Your task is to write down the set in the formal language of set theory by specifying the membership condition of the set. There are many possible answers here, but make sure that the condition you specify actually determines which elements belong to that set. (h) Assume the numbers in this set are natural numbers N. {0, 10, 20, 30, 40, 50, . . . } (i) Ecin U (j) The intersection of Ecin U and F.
Please help. How to solve this on Java language by using only Dynamic Programming? Thank you. We are given a set A of integers. Check whether we can partition A into three subsets with equal sums. It is important to note that all elements should be included in the equally divided subsets; no element should be left out, and none of the elements should be repeated in the subsets.For example: A={4,7,6,2,10,7,10,2} has such a partition: {4,2,10}, {7,7,2},{6,10}Input: A set, A, of integersOutput: if we can partition A into three subsets with equal sums, print subsets otherwise present a suitable message.
Consider the set A of all strings of letters a-f of length 6. A few elements of this set are dcebac, ebaafe, and abeafa. What is the cardinality of each of the following sets? Please indicate which of the principles of multiplication, addition, or inclusion-exclusion you have used in each part. Part A The set A itself Part B The set B a subset of A of strings of length 6 in which no elements are repeated Part C The set C a subset of A of strings which contain the substring fab Part D The set D a subset of A of strings which contain the substring fab or the substring feebb (or both) Part E The set E of strings which contain either the substring fab or the substring baff (or both)
Directions: Use the set- roaster notation to write the following sets, and determine the number of elements that are in a set. 1. Let A={ 1,2,3 }, B={ 3,1,2 },and C={ 1,1,2,3,3,3 }. What are the elements of A? B? and C? How are A, B and C related? 2. Let A={ w,x,y,z } and B= { a,b }. Find AxB? And BxB?
Implement the following Racket functions: You must use recursion, and not iteration. You may not use side-effects (e.g. set!). Transitive? Input: a list of pairs, L. Interpreting L as a binary relation, Transitive? returns #t if L is a transitive relation and #f otherwise. Examples: (display "Transitive? \n") (Transitive? '((a b) (b c) (a c))) ---> #t (Transitive? '((a a) (b b) (c c))) ---> #t (Transitive? '((a b) (b a))) ---> #f (Transitive? '((a b) (b a) (a a))) ---> #f (Transitive? '((a b) (b a) (a a) (b b))) ---> #t (Transitive? '())---> #t

In this exercise we will be processing some data stored as a list of dictionaries in order to be able to answer queries on the data. In our case we simply have a list of student records, where each record is a dictionary that has the student's name and their GPA. An example of the data set is below: students = [{'name': 'Alice', 'gpa': 4.0}, {'name': 'Bob', 'gpa': 3.5}, {'name': 'Cody', 'gpa': 3.75}, {'name': 'David', 'gpa': 3.65}] Your task is to create a function called topStudent which takes in a list of students of the form shown above and finds the name of the student with the highest GPA. For this assignment you can assume that no two students will have the same GPA. where you'll find a class roster of 100 students. Below that is the topStudent function, which you need to complete. roster = [{'name': 'Archy', 'gpa': 3.39}, {'name': 'Nadia', 'gpa': 2.39}, {'name': 'Cesya', 'gpa': 3.34}, {'name': 'Kellie', 'gpa': 2.32}, {'name': 'Jordana', 'gpa': 3.64}, {'name': 'Wilton',…
Transcribed Image Text Let N be the set of all ounting numbers: 1, 2, 3,.... Consider these set definitions: A = {z € N| (4 < =) A (z < 5)} and B- {{4, 5}} Is the equality A = B true? O Yes, it is true. O No, it is not true. o We need more information in order to decide. Not counting N, are we dealing with two sets or one set in this problem? o One set. O Two sets.
In this assignment, you will do an implementation of the Huffman Code. If you have the Data Structures book for this class, on pages 415-421 is the theory for encoding a String using the Huffman Code. There is also a PDF of these pages on the class website. Your task is to develop a proof of concept of the Huffman Code and demonstrate it by taking a String and encoding it. The Huffman Code requires knowledge of a few data structure concepts discussed in class: Priority Queues Binary Trees Recursion Arrays and/or Linked Lists In your program, you will demonstrate an understanding of all these concepts by developing your own priority queue, node, binary tree, array and/or linked list, and use of recursion to support the Huffman Code encryption algorithm. Read through the theory of the Huffman Code in the text and then write a program that can take a String and encrypt it. For example, given a String “Hello World”, the program should apply the Huffman Code algorithm on that…
Implement the following Racket functions: Reflexive? Input: a list of pairs, L and a list S. Interpreting L as a binary relation over the set S, Reflexive? returns #t if L is a reflexive relation over the set S and #f otherwise. Examples: (display "Reflexive?\n") (Reflexive? '((a a) (b b) (c c)) '(a b c)) ---> #t (Reflexive? '((a a) (b b)) '(a b c)) ---> #f (Reflexive? '((a a) (a s) (b b) (c c)) '(a b c)) ---> #f (Reflexive? '() '()) ---> #t You must use recursion, and not iteration. You may not use side-effects (e.g. set!).
implemented a system for maintaining rental contracts for a small parking lot. With our knowledge of ordered structures, we now return to that example to incorporate a new feature—an alphabetical listing of contracts. As customers rent spaces from the parking office, contracts are added to a generic list of associations between renter names and lot assignments. We now change that structure to reflect a better means of keeping track of this information—an ordered list of comparable associations.
Define function p:cat represents set concatenation ◦, which concatenates every pair of strings from both sets using racket. We can specify set concatenation as p1 ◦ p2 = {u · v | u ∈ p1 ∧ v ∈ p2}. Alternatively, we give an inductive specification: ∅ ◦ p2 = ∅ p1 ◦ p2 = prefix(u, p2) ∪ (p'1◦ p2) if p1={u} ∪ p'1.
