Section 7.2.4 presented various ways of defining negatively correlated patterns. Consider Definition 3: "Suppose that itemsets X and Y are both frequent, that is, sup(X) ≥ min sup and sup(Y ) ≥ min sup, where min sup is the minimum support threshold. If (P(X|Y )+P(Y |X))/2 < ϵ, where ϵ is a negative pattern threshold, then pattern X ∪ Y is a negatively correlated pattern." Design an efficient pattern-growth algorithm for mining the set of negatively correlated patterns.

This program reads a file called 'test.txt'. you are required to write two functions that build a wordlist out of all of the words found in the file and print all of the unique words found in the file. remove punctuations using 'string.punctuation' and 'strip()' before adding words to the wordlist. write a function build_wordlist() that takes a 'file pointer' as an argument and reads the contents, builds the wordlist after removing punctuations, and then returns the wordlist. another function find_unique() will take this wordlist as a parameter and return another wordlist comprising of all unique words found in the wordlist. example: contents of 'test.txt': test file another line in the test file output: ['another', 'file', 'in', 'line', 'test', 'the']

Consider the following function main: int main() { int alpha[20]; int beta[20]; int matrix[10][4]; . . } a. write the definition of the function inputarray that prompts the user to input 20 numbers and stores the numbers into alpha. b. write the definition of the function doublearray that initializes the elements of beta to two times the corresponding elements in alpha. make sure that you prevent the function from modifying the elements of alpha. c. write the definition of the function copyalphabeta that stores alpha into the first five rows of matrix and beta into the last five rows of matrix. make sure that you prevent the function from modifying the elements of alpha and beta. d. write the definition of the function printarray that prints any onedimensional array of type int. print 15 elements per line. e. write a c11 program that tests the function main and the functions discussed in parts a through d. (add additional functions, such as printing a two-dimensional array, as needed.)
