Exercise 2: Write a program that reads n values from an input screen and stores them in a list T1, then fills another list T2 with values from T1 where any consecutive duplicated values appears only one time, i.e. removes consecutive duplicated values. If you run your program with the following input data: 4 7 3 3 3 6 14 14 10 5 7 7 7 7 2 2 4 4 4 10. Your output should be as follows: Number of elements in T1: 20 T1: 4 7 3 3 3 6 14 14 10 5 7 7 7 7 2 2 4 4 4 10 Number of elements in T2: 11 T2: 4 7 3 6 14 10 5 7 2 4 10 Your program should have at least these 3 functions: 1. main():displays the original list T1, the number of elements of T2 and list T2 2. readData(():reads data from input screen into a list 3. removeConsecutiveDuplicates(): takes a list and remove any consecutive duplicated numbers

18. The mean of a set of numbers is the average computed by dividing the sum of the numbers by the quantity of the numbers. Complete method getMean below. // precondition: // postcondition: list is a non-empty array of integers. getMean returns the mean of the integers stored by list. public static double getMean(int[] list) {

3. Complete the program Student Records that simulates a student records system. The program reads a list of student ids, names, and GPAS from a file exam.txt, and stores the information in parallel array lists ids, names, and gpas. Sample input (exam.txt): 132 Woody 4.1 465 Buzz 3.1 443 Rex 2.8 124 Hamm 3.3 337 Jessie 4.2 Your program will display a GPA report. You must include a method named reportByGPA (...) that accepts the required array lists and minimum GPA and displays the list of students that meet the criteria. Sample output: Enter the minimum GPA: 4.0 Students with GPA of 4.0 or higher 132 Woody, GPA: 4.1 337 Jessie, GPA: 4.2 end of program import java.util.ArrayList; import java.util.Scanner; import java.io.File; import java.io.FileNotFoundException; public class Student Records { public static void main(String[] args) throws FileNotFoundException ( Scanner f = new Scanner (new File ("exam.txt")); Scanner kb = new Scanner (System.in); ArrayList ids = new ArrayList ();…

Q2: a. Write an algorithm that searches a sorted list of n items by dividing it into three sublists of almost n/3 items. This algorithm finds the sublist that might contain the given item and divides it into three smaller sublists of almost equal size. The algorithm repeats this process until it finds the item or concludes that the item is not in the list. Dry run the above algorithm to find the value 240. A[] = {10,15,20,60,65,110,150,220,240,245,260,290,300,460,470,501}

Python please: Given the input file input1.csv write a program that first reads in the name of the input file and then reads the file using the csv.reader() method. The file contains a list of words separated by commas. Your program should output the words in a sorted list. The contents of the input1.csv are: hello,cat,man,hey,dog,boy,Hello,man,cat,woman,dog,Cat,hey,boy Example: If the input is input1.csv the output is: ['Cat', 'Hello', 'boy', 'boy', 'cat', 'cat', 'dog', 'dog', 'hello', 'hey', 'hey', 'man', 'man', 'woman'] Note: There is a newline at the end of the output.

Array List: Write a program that reads in words and prints them out in reverse order. Complete this code.

The function interleave_lists in python takes two parameters, L1 and L2, both lists. Notice that the lists may have different lengths. The function accumulates a new list by appending alternating items from L1 and L2 until one list has been exhausted.  The remaining items from the other list are then appended to the end of the new list, and the new list is returned. For example, if L1 = ["hop", "skip", "jump", "rest"] and L2 = ["up", "down"], then the function would return the list: ["hop", "up", "skip", "down", "jump", "rest"]. HINT: Python has a built-in function min() which is helpful here.    Initialize accumulator variable newlist to be an empty list Set min_length = min(len(L1), len(L2)), the smaller of the two list lengths Use a for loop to iterate k over range(min_length) to do the first part of this function's work. On each iteration, append to newlist the item from index k in L1, and then append the item from index k in L2 (two appends on each iteration). AFTER the loop…

Write a function that will accept a list of integers and return the sum of the contents of the list(……if the list contains 1,2,3 it will return 6…..)

Binary Search of Strings1. Write a version of the selection sort algorithm presented in the unit, which is usedto search a list of strings.2. Write a version of the binary search algorithm presented in the unit, which isused to search a list of strings. (Use the selection sort that you designed aboveto sort the list of strings.)3. Create a test program that primes the list with a set of strings, sorts the list, andthen prompts the user to enter a search string. Your program should then searchthe list using your binary search algorithm to determine if the string is in the list.Allow the user to continue to search for strings until they choose to exit theprogram
