Question 2 Get the Array ADT implementation from your textbook to work. Demonstrate that your code works as specified in the ADT. You are free to change internal names so that you can make better sense of the code provided in the textbook. You will need this code for later exercises Your implementation must provide _str_() and repr_() methods, in addition to the methods implemented in the textbook. The output of these methods must return each value separated with a comma in a string. For example, if the array has values 10, 12, 14, 16, and 18, these methods must return the string "10, 12, 14, 16, 18" Your code should support following operations: import random array = Array ( 100 ) for i in range( len( array ) ): # array[i] = random.random() # Print individual values in the array. # for value in array: # print(value) # Print the entire array. # print(array )

In writing a general-purpose sort method in Java, the sort method needs to compareobjects. There are two ways to give the sort method the code to compare objects,implementing the interfaces Comparable and Comparator respectively. Extend Article class toimplement Comparable interface so that the default sorting of the Articles is by its volume
Nonscalar types, such as arrays, records (structures), and variant records (unions) also contain information. The rules for information flow classes for these data types are built on the scalar types. Consider the array a: array 1 .. 100 of int; First, look at information flows out of an element a[i] of the array. In this case, information flows from a[i] and from i, the latter by virtue of the index indicating which element of the array to use. Information flows into a[i] affect only the value in a[i], and so do not affect the information in i. Thus, for information flows from a[i], the class involved is lub{ a[i], i }; for information flows into a[i], the class involved is a[i]. Above is the infromation flow security mechanism for arrays similarly write one for structures/Records. Below is the small info on Structures. The structure consists of several fields, each of which acts like a variable. Say you have a structure with two integer fields, x and y. You want to assign the value…

Make a BST implementation that uses three arrays to represent the BST: an array for keys, an array for left and right array indices, and an array for right array indices. The maximum size supplied in the constructor should be preallocated to the arrays. Compare the performance of your programme to that of the typical implementation.
Java (Sort, IComparable) The librarian wants to sort the media in the ArrayList by title. For this purpose, the Medium class should implement the Comparable interface. Implement a Method compareTo (...) in the abstract class Medium. Then sort the Media in the ArrayList. Implement the sort method in the Zettelkasten class.This should, by Parameters can be selected, the media contained in descending ("A" → "Z") or ascending ("Z" → Sort "A") by title. Please do not implement your own sorting algorithm, but rather simply use a suitable method of the ArrayList class. Increase the efficiency of the note box. The note box should remember whether the The media contained therein are already sorted, e.g. by calling sort earlier. In this case, re-sorting should be omitted.
