1. Use a below-given starter code. Use StackInterface.(h), and ArrayStack.(h,cpp). You will write your own StackDriver.cpp application file. IT'S IN C++Also...If the class that you create is Star, remember that you will declare your stack as follows:ArrayStack<Star> myStarStack;and you will push, pop, and peek Star objects.2. Create your own class definition. I should have at least one attribute, a constructor, and set and get methods for each attribute in your class.NOTE: If your class is offensive your lab will be rejected and you will receive a score of zero. I'm sorry I have to say this but there is a history of this happening and it is not appropriate.3. Write a driver program that exercises the Stack class from the downloaded starter code. Create multiple instances of your own class and demonstrate the stack operations: push, pop, and peek. ( you write your own class that you will put on the stack and you will write a driver that pushes, peeks, and pops your class items…
write in C your own static library for dynamic allocation of memory (library should allocate and deallocate) using freelists and mmap and commands for executing this in Linux?
What is the best way to implement a stack or a queue so that it can hold an arbitrary number of elements? Select one: a. Using an array, and throwing an exception when the stack or queue is full. b. By creating a bigger array when the stack or queue is full, and copying the elements from the original array. c. Using linked lists to store the collection of elements.
The question should be done in C++, please give explanation and running result. 1. For this question, we need to provide more information about where the mismatch of the text file is happening. Write a recursive function called list_mismatched_lines that takes 2 filenames as input arguments and displays to the screen all mismatched lines in those files. This function should use hashing techniques and shall not compare strings to detect mismatch. The signature of this function should be: void list_mismatched_lines(std::string file1, std::string file2); In file1.txt, it contains "My dear C++ class. I hope that you enjoy this assignment. " In file2.txt, it contains "My dear C++ class. I hope that you like this assignment. " Example: Running the following line of code, should print to the screen the mismatched lines only, from both files. list_mismatched_lines(file1, file2); The following output should be seen on the screen: file1.txt: I hope that you enjoy this assignment.file2.txt:…
Need help making a java file that combines both linearSearch and binarySearch •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. //code from textbook //linearSearch public static <T> boolean linearSearch(T[] data, int min, int max, T target) { int index = min; boolean found = false; while (!found && index <= max) { found = data [index].equals(target); index++; } return found; } //binarySearch public static <T extends Comparable<T>> boolean binarySearch(T[] data, int min, int max, T target) { boolean found = false; int midpoint = (min + max)/2; if (data[midpoint].compareTo(target)==0)…
Design and implement a service that simulates PHP loops. Each of the three loop variants should be encapsulated in an object. The service can be controlled via a parameter and execute three different simulations. The result is returned as JSON. The input is an array consisting of the letters $characters = [A-Z]. -The For loop should store all even letters in an array.-The Foreach loop simulation is to create a backward sorted array by For loop, i.e. [Z-A] .-The While loop should write all characters into an array until the desired character is found. Interface:-GET Parameter String: loopType ( possible values: REVERSE, EVEN, UNTIL )-GET parameter String: until (up to which character) Output:JSON Object: {loopName: <string>, result: <array> }
Implement a password cracker using C++ Source code must be well documented (comments). You will be provided with an unsalted hashed password file that contains password hashes for different users. Also, you will be provided with a dictionary file(in clear text) containing the most common passwords. You should implement the offline dictionary attack by trying SHA1 and SHA2 algorithms. Also, your program should brute force all possible alphanumeric(only small cases) passwords from 1 to 4 characters using SHA1 and SHA2 algorithms against all hashed passwords left from the offline dictionary attack (if any).

What would be a way in implementing the Josephus problem in C++ using a vector or a list? That takes in three parameters, one the number of knights for the knight parameter. The second parameter, "skip", is the number of knights to skip and to execute the next night. Then the third parameter "start", is the index of the knight to execute first.
