Question 4Question 4 (6 marks)Not yetLet twoD be a two-dimensional array, for example, as follow:answeredMarked out ofint [][] twoD = {{2, 3, 4}, {5, 6, 7, 8}, {2, 4, 6}, {1, 2, 3, 4, 5}};6.00Write Java code fragment to process the elements of each row. In each row, we wish to extractthe odd integers, multiply by them, and display the result. Note that you need to use lambda andstream to process each row.P Flag questionIf you insert the 2D array and your code fragment in main method, you should produce thefollowing output: (you can see row 3 has no odd integer, a blank line is displayed)25 491 9 25Write a complete Java program to test your design.

def analyze_file (filename: str, pos_words: List [str], neg_words: List [str]) -> Given the name of a file, a list of positive words (all in lowercase), and a list of negative words (all in lowercase), return some interesting data about the file in a tuple, with the first item in the tuple being the positivity score of the contents of this file, and the rest of the item: being whatever else you end up analyzing. (Helper functions are highly encouraged here.) How to calculate positivity score: For every word that is pos itive in the file (based on the words in the list of positive words) add 1 to the score. For every negative word (based on the list of negative words), subtract 1 from the score. Any neutral words (those that do not appear in either list) do not affect the score in any way. pass
Q1. The last post didnt include the items in the database. Need a different function for the python program display_ticket below: def display_tickets():t = Texttable()tickets=cur.execute('''SELECT * FROM tickets''')for i in tickets:t.add_rows([['tid', 'actual_speed','posted_speed','age','violator_sex'],list(i)])print()print(t.draw())print() Q2. Also need a different function for the python program add_ticket below: def add_tickets():actual_speed=int(input("enter actual speed:"))posted_speed=int(input("enter posted speed:"))age=int(input("enter age:"))sex=input("Male or Female:")cur.execute('''INSERT INTO tickets(actual_speed,posted_speed,age,violator_sex) VALUES(?,?,?,?)''',(actual_speed,posted_speed,age,sex))con.commit() If you'd like to see what thousands of traffic tickets look like, check out this link: https://www.twincities.com/2017/08/11/we-analyzed-224915-minnesota-speeding-tickets-see-what-we-learned/
Write a loop that sets newScores to oldScores shifted once left, with element 0 copied to the end. Ex: If oldScores = {10, 20, 30, 40}, then newScores = {20, 30, 40, 10}.Note: These activities may test code with different test values. This activity will perform two tests, both with a 4-element array (int oldScores[4]). See "How to Use zyBooks".Also note: If the submitted code tries to access an invalid array element, such as newScores[9] for a 4-element array, the test may generate strange results. Or the test may crash and report "Program end never reached", in which case the system doesn't print the test case that caused the reported message. import java.util.Scanner; public class StudentScores { public static void main (String [] args) { Scanner scnr = new Scanner(System.in); final int SCORES_SIZE = 4; int[] oldScores = new int[SCORES_SIZE]; int[] newScores = new int[SCORES_SIZE]; int i; for (i = 0; i < oldScores.length; ++i) { oldScores[i] = scnr.nextInt(); } for (i = 0; i…

Here is the iterative implementation of binary search: For each call to binary_search below, indicate how many times the code inside the while loop will execute. animals = ["aardvark", "cat", "dog", "elephant", "panda"] 1. binary_search("elephant", animals) 2. binary_search("dog", animals) 3. binary_search("anteater", animals)

In python: student_dict is a dictionary with students' name and pedometer reading pairs. A new student is read from input and added into student_dict. For each student in student_dict, output the student's name, followed by "'s pedometer reading: ", and the student's pedometer reading. Then, assign average_value with the average of all the pedometer readings in student_dict..
//From what I can tell, the answer provided does not answer my question. Asking again. Please read. Write a Java program that implements both Linear Search and Binary Search. The program willtake a collection of objects (generic type data) as input and print the number of comparisons neededto find a target element within that collection.You will create the following two Java classes:1. SearchCombo.java : Code for both linearSearch and binarySearch will be in this class. Youmay take help from the textbook Chapter 9, Section 9.1. However, note that the design require-ments are different from the textbook code.•Both search methods must use the Comparable<T> interface and the compareTo() method.•Your program must be able to handle different data types, i.e., use generics.•For binarySearch, if you decide to use a midpoint computation formula that is different fromthe textbook, explain that formula briefly as a comment within your code. 2.
