I'm not sure how to write a copy constructor that would construct a copy that would append rather than push, such that the result isn't backwards. Below is a provided main.h file for context purposes main.h: #pragma once #include <iostream> class Node { public: char letter; Node* down; Node(char c) : letter(c), down(nullptr) {} }; class Stack { private: Node* top_ = nullptr; public: Stack() = default; void push(char c); char top(); void pop(); bool isEmpty(); void clear(); friend std::ostream& operator<<(std::ostream& os, Stack const& s); ~Stack(); Stack& operator=(Stack other); Stack(Stack const& other); void Stack::append(char c); };
In C++, you are going to write a program that implements a doubly linked list. The data must be read from the files and you can put the file names in your program. Letters.txt contains 26 English Letters: Copy the following exactly as it is into own .txt file to test: ABCDEFGHIJKLMNOPQRSTUVWXYZ Sequence.txt contains a list of numbers. Copy the following exactly as is into another .txt file3,-3,19,-19,18,1,-2,3,-18,17,1,-3,-13,14 You need to 1. Create a doubly linked list by reading the 26 letters from Letters.txt. 2. Sequence.txt file contains a sequence of relative letter positions. The initial position is at the beginning of the list which is ‘A’. The first number in the sequence is ‘3’. So the current position will move forward for three steps. Then the first letter to output is ‘D’ and now the current position is at ‘D’ as well. The second number in the sequence is ‘-3’. Then the second letter to output is the third element backward from the current position which is ‘A’. You…
Write a program in C/C++ that reads N number of nonnegative decimal numbers from a user and creates a hash table to store the numbers. The output of the program displays the order of the numbers in the hash table. The program then prompts the user to enter a target value. The program searches the target value to the hash table, and displays the search outcome. For simplicity, let’s assume that N = 6 and the size of the hash table is 10. Use this hash function in your code h(k) = 2k+3 where k is the key value. Use linear probe method for collision resolution. Example test run Test Run 1: Enter 6 elements: 3 2 9 6 11 13 Hash table order: 13 9 - - - 6 11 2 - 3 Enter the target: 1111 is located at index: 6 Test Run 2: Enter 6 elements: 3 2 9 6 11 13 Hash table order: 13 9 - - - 6 11 2 - 3 Enter the target: 1515 is not in the table

Write a program that takes as input an arithmetic expression. The program outputs whether the expression contains matching grouping symbols (brackets and parentheses). For example, the arithmetic expressions {25 + (3 – 6) * 8} and 7 + 8 * 2 contains matching grouping symbols. However, the expression 5 + {(13 + 7) / 8 - 2 * 9 does not contain matching grouping symbols. You must use a stack and/or queue. USE THE FOLLOWING DATA FILE //Header file: stackADT.h #ifndef H_StackADT#define H_StackADT template <class Type>class stackADT{public:virtual void initializeStack() = 0;//Method to initialize the stack to an empty state.//Postcondition: Stack is emptyvirtual bool isEmptyStack() const = 0;//Function to determine whether the stack is empty.//Postcondition: Returns true if the stack is empty,// otherwise returns false.virtual bool isFullStack() const = 0;//Function to determine whether the stack is full.//Postcondition: Returns true if the stack is full,// otherwise returns…
A Lo Shu Magic Square is a grid with 3 rows and 3 columns. Create a Lo Shu Magic Square in Python with these properties:-A grid that contains the numbers 1-9.-The sum of each row, each column, and each diagonal all adding up to the same number.-Simulate the magic square using a two-dimensional list.-It must throw an exception if any character other than 1 – 9 is selected.-The program must give an message explaining that wrong input has been provided.-The program has to prompt the user until the condition has been satisfied. It should prompt the user to enter a number from 1-9.-The program can only use each number once.-When the program starts, it must explain how to play the game. Those who have never heard of it should be able to play. The directions should be clear.-Show an example of a Lo Shu Magic Square after each game.-The program must allow users to play the game until they choose to quit.It also must keep track of wins and losses.The user should be given a choice to choose a…
