Write a program that reads a list of words. Then, the program outputs those words and their frequencies. The input begins with an integer indicating the number of words that follow. Assume that the list will always contain fewer than 20 words. Ex: If the input is: 5 hey hi Mark hi mark the output is: hey- 1 hi - 2 Mark 1 hi - 2 mark Hint: Use two vectors, one vector for the strings and one vector for the frequencies. 390596.2449804.qx3zay7 LAB ACTIVITY I 8 9 10 보호 1 #include 2 #include 3 #include 1 12 5.18.1: LAB - Word frequencies 11 } using namespace std; int main() { /* Type your code here. */ return 0; main.cpp Load default template...

Write a "Python" program that reads coefficients and the right-hand side vector of a linear equation system from a given file (input.txt). The last row of the "input.txt" file is the right-hand side vector of a linear equation system. The coefficients of the linear equation will be integer as shown below. 4x0 +x1 = 3 2x0 +5x1 = 1 The content of "input.txt" will be: Size=2 4 1 25 31 (a) Print the given matrix to the "output.txt" file as shown below: The content of the "output.txt" file: +4x0 +1x1 = 3 +2x0 +5x1 = 1 (b) solve the given linear equation system using the Gauss Elimination and Jacobi methods. Print the solutions to the "output_results.txt". The content of the "output_results.txt" file should be (the 4th digit after the decimal point will be rounded): The solution of the system by Gauss Elimination: x1=0.7778 x2=-0.1111 The solution of the system by Jacobi Method: x1=0.7778 x2 -0.1111 Note: Please write your code by writing functions one for Gauss Elimination Method, one for…

Complete the rotate_text() function that takes 2 parameters, a string data and an integer n. If n is positive, then the function will shift all the characters in data forward by n positions, with characters at the end of the string being moved to the start of the string. If n is 0 then the text remains the same. For example: rotate_text('abcde', rotate_text('abcde', rotate_text('abcde', 1) would return the string 'eabcd' 3) would return the string 'cdeab' 5) would return the string 'abcde' rotate_text('abcde', 6) would return the string 'eabcd' ... and so on. If n is negative, then the function will shift the characters in data backward by n positions, with characters at the start of the string being moved to the end of the string. For example: rotate text('abcde', -1) would return the string 'bcdea'
Using c++ Contact list: Binary Search A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes as input an integer N that represents the number of word pairs in the list to follow. Word pairs consist of a name and a phone number (both strings). That list is followed by a name, and your program should output the phone number associated with that name. Define and call the following function. The return value of FindContact is the index of the contact with the provided contact name. If the name is not found, the function should return -1 This function should use binary search. Modify the algorithm to output the count of how many comparisons using == with the contactName were performed during the search, before it returns the index (or -1). int FindContact(ContactInfo contacts[], int size, string contactName) Ex: If the input is: 3 Frank 867-5309 Joe…

Add 3 to the values of x that are even. d. Set the values of x that are less than the mean to zero. e. Set the values of x that is greater than the mean to their difference with the mean.
PYTHON Complete the function below, which takes two arguments: data: a list of tweets search_words: a list of search phrases The function should, for each tweet in data, check whether that tweet uses any of the words in the list search_words. If it does, we keep the tweet. If it does not, we ignore the tweet. data = ['ZOOM earnings for Q1 are up 5%', 'Subscriptions at ZOOM have risen to all-time highs, boosting sales', "Got a new Mazda, ZOOM ZOOM Y'ALL!", 'I hate getting up at 8am FOR A STUPID ZOOM MEETING', 'ZOOM execs hint at a decline in earnings following a capital expansion program'] Hint: Consider the example_function below. It takes a list of numbers in numbers and keeps only those that appear in search_numbers. def example_function(numbers, search_numbers): keep = [] for number in numbers: if number in search_numbers(): keep.append(number) return keep def search_words(data, search_words):

Javascript Use a for/of loop to iterate over the array of students. For each student, use a template literal to print out their name, age, and major in a formatted string. (e.g. John is 18 years old and is studying Computer Science.) Within the template literal, use object dot notation to access the name, age, and major properties of the student object. Use a console.log() to print out the formatted string for each student. Test the code by running it and verifying that it prints out the details of each student in a formatted string.============================================================================== const students = [ { name: "John", age: 18, major: "Computer Science" }, { name: "Newton", age: 19, major: "Mathematics" }, { name: "Barry", age: 20, major: "Physics" }, ]; // Iterate through the array of objects students using for/of // Print a message to the console that includes the student's name, age, and major // Example: John is 18 years old and…
