**11.18** Java Solve (ArrayList of Character) Using the following header, create a method that produces an array list of characters from a string: toCharacterArray public static ArrayListCharacter> (String s) ToCharacterArray("abc"), for example, returns an array list containing the characters 'a', 'b', and 'c'.
8) Write a Java code segment to sum (total) only the positive (greater than zero) values contained in a one dimensional array of integers named intArr that has already been filled with a variety of values (from -250 to +250, for example) and print the final total of the positive contents with an appropriate message.
6.28 In Python, Write a program that replaces words in a sentence. The input begins with word replacement pairs (original and replacement). The next line of input is the sentence where any word on the original list is replaced. Ex: If the input is: automobile car manufacturer maker children kids The automobile manufacturer recommends car seats for children if the automobile doesn't already have one. the output is: The car maker recommends car seats for kids if the car doesn't already have one. You can assume the original words are unique. END WITH A NEW LINE

iv) Write a JAVA program to merge two sorted arrays into a single sorted array. Take the sample arrays given below and print the result in the output. The time complexity of the program should be O(N+M) where N and M are the sizes of both the arrays. int []arr1 = {1, 6, 10, 14} int []arr2 = {2, 4, 5, 11, 16, 19} Print the merged array in the output.

Using C++, Write a program (without using void) to produce the first 100 Fibonacci numbers. A Fibonacci number is one that is the product of the prior two generated numbers. The sequence is seeded with the values of 0 and 1, so that the sequence starts off as 0 1 1 2 3 ... Fibonacci numbers are used in computing hash table locations for file management systems
9.5.1: Use the addChoice method to add any needed instance variables. Provide a different implementation of ChoiceQuestion. Instead of storing the choices in an array list, the addChoice method should add the choice to the question text. For this purpose, an addLine method has been added to the Question class. ChoiceQuestion.java: /** A question with multiple choices.*/public class ChoiceQuestion extends Question{ // Add any needed instance variables, but don't store the choices // The choices should be added to the text of the superclass /* Your code goes here */ /** Constructs a choice question with a given text and no choices. @param questionText the text of this question */ public ChoiceQuestion(String questionText) { /* Your code goes here */ } /** Adds an answer choice to this question. @param choice the choice to add @param correct true if this is the correct choice, false otherwise */ public void…
