Question 2 [5 points) State if each of the below statements is True or False 1 2 3 The Compiler skips comments. A function can return a value of type array. An array index starts with 1. Pass by value is the default in CH, except when passing arrays as arguments to function The default storage class for local variables is static. A pointer provides an indirect means of accessing the value of a particular data item The logical operators...
Consider the following mergeSortHelper method, which is part of an algorithm to recursively sort an array of integers. /** Precondition: (arr.length == 0 or 0 <= from <= to <= arr.length) * arr.length == temp.length */ public static void mergeSortHelper(int[] arr, int from, int to, int[] temp) { if (from < to) { int middle = (from + to) / 2; mergeSortHelper(arr, from, middle, temp); mergeSortHelper(arr, middle + 1, to, temp); merge(arr, from, middle, to, temp); } } The merge method...

Design a program that allows you to experiment with different sort algorithms in Java. This program should allow you to easily plug-in new sort algorithms and compare them. Assume that input data is generated randomly and stored in a text file (have no less than 2000 items to sort). Do not restrict your program to only one data type, or to one ordering relationship. The data type, ordering relationship, and the sorting method must be input parameters for your program....
QUESTION 1 Using the following declarations and a member of the Array class, int [ ] bArray = new int [10]; int location; Using a method in the Array class, write a statement that would change the order of the elements in the bArray array. The contents of the first cell should hold what was in the last cell. The second cell should hold what was in the next to last cell. __________________________ HINT: You must write the full statement...
A method called linearSearch(), which takes as parameters an array of int followed by three values of type int, and returns a value of type int. The first int parameter represents a key, the second int parameter represents a starting position, and the third int parameter represents an end position. If the key occurs in the array between the start position (inclusive) and the end position (exclusive), the method returns the position of the first occurrence of the key in...
