2. lambda
3. cons, car, cdr, list, list?, append, empty?, length, equal?
4. and, or, not
5. if, cond
6. map, append-map, andmap, ormap, filter
7. +, -, /, *
8. Functions you implement

Implement the following Racket functions:

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?

Implement the following Racket functions: Symmetric? Input: a list of pairs, L. Interpreting L as a binary relation, Symmetric? returns #t if L is a symmetric relation and #f otherwise. Examples: (display "Symmetric?\n") (Symmetric? '((a a) (a b) (b a) (b c) (c b))) ---> #t (Symmetric? '((a a) (a b) (a c) (c a))) ---> #f (Symmetric? '((a a) (b b))) ---> #t (Symmetric? '()) ---> #t
Write a python 3 program for the following: Comparing large numbers Write a program which checks whether a given relation is true for a given pair of numbers. Input You are provided with an unknown number of test cases. Each test case consists of a natural number, which is followed by a white space, relational operator (==, !=, >= or <=), white space. and another natural number All test cases are separated with a new line character. You can assume that no number has more than 1000 digits. Output A binary sequence should appear on the output. ith element of the sequence should be equal to 1 or 0, depending on whether the corresponding relation is true or false. All elements of the sequence should be separated with a new line character. Example Input: 100 == 200 200 <= 100 200 >= 100 Output: 0 0 1
The following java function executes an SQL query based on the inputs from the combo boxes and text box from the screen shown and is supposed to return a list of items that match the query. The input string is a string of the field, operator and criteria text from the boxes separated by commas. However, the method is not currently functional and must be modified to enact the query. Modifiy the function so that it works properly. An image of the database schema has also been attached as well as the product class. public List<Product> getProductByCriteria(String criteria) { if (openConnection()) { try { List<Product> items = new ArrayList<>(); Product temp = null; String[] fields = criteria.split(","); String query = "SELECT * FROM products WHERE " + fields[0] + fields[1] + fields[2]; stmt = conn.prepareStatement(query); ResultSet rs = stmt.executeQuery(); while…

Part 1: autocomplete term. Write an immutable data type Term.java that represents an autocomplete term-a query string and an associated integer weight. You must implement the following API, which supports comparing terms by three different orders: lexicographic order by query string (the natural order); in descending order by weight (an alternate order); and lexicographic order by query string but using only the first r characters (a family of alternate orderings). The last order may seem a bit odd, but you will use it in Part 3 to find all query strings that start with a given prefix (of length r). public class Term implements Comparable { // Initializes a term with the given query string and weight. public Term (String query, long weight) // Compares the two terms in descending order by weight. public static Comparator byReverseWeight0rder () // Compares the two terms in lexicographic order, // but using only the first r characters of each query. public static Comparator…
This assignment needs to be done in c++ languageCase study:An event company asks you to design the data structure and program prototype for theirrunning event system. The participant for the running event is expected to reach more than1000 in various categories. You decided to use hashing function method to store theinformation for each participant’s BIB number in the hash table. To begin the problem solving, suppose that 10 registered runners need to be stored in a hashtable, HT, with a size of 13. The sample BIB number of the runners are: 101, 102, 103, 104, 107,111, 121, 217, 157, and 185.Furthermore, you set the hash function to determine the index of the participant in the HT as:hash(BIB) = BIB % table size (or 13)However, if the hash index given by hash(BIB) is already occupied (collision), the linear probinghash function will be used as:hash(BIB) = (Hash(BIB)+1) % 17and, further collision with hash function:hash(BIB) = (Hash(BIB)+2) % 17or, hash(BIB) = (Hash(BIB) + n) % 17,…

A transaction database is a set of transactions completed in a supermarket database. Each transaction is a set of items. For example, consider the following transaction database. It contains 5 transactions (t1, t2, ..., t5) and 5 items (1,2, 3, 4, 5). For example, the first transaction represents the set of items 1, 3 and 4. It is important to note that an item is not allowed to appear twice in the same transaction and that items are assumed to be sorted by lexicographical order in a transaction. Transaction id Items t1 {1, 3, 4} t2 {2, 3, 5} t3 {1, 2, 3, 5} t4 {2, 5} t5 {1, 2, 3, 5} What is the output of the Apriori algorithm run on the previous transaction database with a minimum support of 40 % (2 out of 5 transactions)?
Computer Science Done in Perl. Someone gave me a wrong/incomplete answer. Write a function, hashsum, which takes a hash reference as its first argument and an array reference as its second argument. The function should take the elements of the array and use them as keys in the hash. The values in the hash corresponding to the keys in the array should be totaled, and the sum should be returned to the user. If a key passed in the array does not exist in the hash, ignore it. Write a sample program to call this function.
