Introduction

<标题>In this assignment you will perform a parallel breadth-first search (BFS) of the 4×3 Sliding Tile state space. The result of this search will be that the distance of every state in the state space from the initial configuration will be stored in an array. In C++ you can only access items in an array using an integer offset. Thus, we cannot directly map between our Sliding Tile puzzle class and an element in the depth array. Luckily, there is a 1-to-1 mapping between states in the puzzle and integers between 0 and 12!/2. We can perform this mapping using what are called “Ranking” and “Unranking” functions. A ranking function will convert a state into an integer, and an unranking function will convert an integer into the corresponding state. T

<标题>Project 2: Integer Arithmetic Expression Evaluator

<标题>Project Objective:

<标题>1. get familiar with the process of completing a programming project.

2. learn how to use and manipulate arrays.

3. understand precedence and associative rules.

4. use program selection: if, if-else, switch statements.

<标题>5. use basic loops (while, do-while, for) for repetition.

Project Description:

<标题>In this project, you will design and implement a program to evaluate an arithmetic

expression. The arithmetic expression will contain only integers, both positive and negative, and

<标题>the following six basic binary operators +, -, %, /, *, and ^ as well as parentheses ().

Your program should read in the expression from an input file. The input file has a

<标题>specific format, which is described below. After reading the expression, you first will need to

evaluate all the negative operands in the expression; next you will evaluate the expression inside

<标题>the parentheses; followed by the power operator ^, then *, /, and % operators, and f

Design and implement your own reusable implementations of the stack and queue ADTs in Java. The purpose of this question simply is to help you get the feel for the design of reusable classes. Thus the actual data structure programming is fairly straightforward, and you have been given most of the structure of the code. Read the following description ofDouble Ended Queues.

A?doubly-ended queue?is often called a?deque. The interface for a deque is the following (which is slightly different than the one given in the textbook):

<标题>public interface Deque { public int size(); public boolean isEmpty(); public void insertFirst(Object o); public void insertLast(Object o); public Object removeFirst() throws EmptyStructureException; public Object removeLast() throws EmptyStructureException; public Object firstElement() throws EmptyStructureException; public Object la

<标题>C++多線程程序作業代寫，實現多線程任務分配

<标题>In this lab you’ll implement a program which uses multiple threads to divide up a simple problem

<标题>into independent sub-tasks. Source code for this lab is supplied in Lab11Source.zip .

<标题>Write the function ThreadedSum which is declared as:

You’ll find an empty function definition in main.cpp in the supplied source code. This function

should :

1. Allocate an array on the heap of type double with arraySize elements . This may get too large

<标题>for the stack, so make sure you allocate it on the heap (free store).

<标题>2. Run numThreads threads, each of which initializes an approximately equal portion of the

array. For example, if numThreads is 8, each thread should initialize 1?8 of the array. Make

sure you handle round-off correctly if arraySize is not an even multiple of numThreads. Each

element of the array should be initialized to the square root of the index of the element.

<标题>3. Wait for all of the initialization threads to complete,

In this lab you will convert your templated LList class to a SharedQueue class (you may adapt your own code or use the Lab 9 Solution). The shared queue can be safely used by many different threads without causing memory corruption. You can download the source code for this lab from Lab12Source.zip<标题>. Create a project called Lab12 and add the source code from t
