- For the Assignment 5 (Part 2), Routes v.2 at the end of this module you will create a Route class that has a member a "bag" of Leg objects. The bag is to use a vector of pointers, but since all the objects in the bag are to be Leg s, it's okay to use Leg* instead of void* in the bag's declaration. You wrote its first constructor in a previous exercise. Now write a second one. (You may refer to the Assignment page to refer to the completed class declarations of Leg and Route classes). Assume that class Leg has data member C strings const char* const beginCity; and const char* const endCity; that are available to Route by a friend relationship. Write a constructor function for a Route class that takes exactly two parameters: a constant Route object reference to an already-existing Route , and a constant Leg object reference to be appended to the end of that Route to form the new Route . Here's the algorithm: Copy the first parameter's bag into the host object's bag. If the endCity of…Is it feasible to quickly access frequently used operators while dealing with enumeration types, such as the arithmetic operators and the stream operators? Is it possible to get a satisfying outcome by, say, overloading these operators? What are the benefits and drawbacks of this approach?In the C (and therefore C++) language, there is a `union` type. For example typedef union { struct{unsigned int red:8, green:8, blue:8}; unsigned int rgb:24 } color; creates a new data type for color, so if `color C = {255, 0, 0}` then `C.red==255` and `C.rgb==0×FF0000`. In essence, the memory associated with the color components has two different names. This is an example of: O Data Types Simplicity Aliasing Syntax Design Expressivity Exception Handling O Orthogonality O Support for Abstraction Type Checking
- Is it possible to quickly access frequently used operators while dealing with enumeration types, such as the arithmetic operators and the stream operators? Is it possible to get a satisfying outcome by, say, overloading these operators? What are the benefits and drawbacks of this approach?Consider a system with the four access operations read, write, grant, and revoke. You can use grant not only to give other subjects read and write access, but also to grant them the right to grant access to the objects you own. Which data structure and algorithm would you use to implement the grant and revoke operation so that you can revoke all access to an object you own?Explore the role of generics in conjunction with the Comparable interface. How do generics enhance type safety when sorting collections of objects?
- This is supposed to test your understanding of Java streams and lambda expressions. Specifically how to create a nonparallel and parallel stream. Intermediate operations, such as map, flatMap, and filter. The terminal operation collect. How to work with java lambda functions with these operations. And efficient programming. This assignment is not meant to be exhausting, in the ideal situation, you will only have to write 25 lines of code to complete this entire assignment. You are to fill in the code in the StreamsHomeWork.java file. You may find a description of what is to be performed for each function below or in that java file provided. Please keep in mind that all the functions have a timelimit in the milliseconds, the exact time for each function is documented below. Please fill in the functional code in the StreamsHomeWork.java file and submit the StreamsHomeWork.java file to Grader Than. Note: The last two functions of the assignment can be used to help you select winning…Implement the code for below assignment Map (the mapper function) EmitIntermediate(the intermediate key,value pairs emitted by the mapper functions) Reduce (the reducer function) Emit (the final output, after summarization from the Reduce functions)We provide you with a single system, single thread version of a basic MapReduce implementation. Task The input is a number of test cases with two matrices each. A single test case will look like: The required output is to print the product of the two matrices in the format shown. The code for the MapReduce class, parts related to IO etc. has already been provided. However, the mapper and reducer functions are incomplete. Your task is to fill up the mapper and reducer functions appropriately, such that the program works, and outputs the product of the two matrices, in row-wise manner. Also, this program outputs certain information to the error stream. This information has been logged to help beginners gain a better understanding of the the…An “inverted file” is a critical data structure for implementing applications like the index of a book, or a web search engine. Given a document D (which can be viewed as an unordered, numbered list of words), an inverted file is an ordered list of words L such that for each word W in L, we store the indices of the places in D where W appears. Write a C# program (from scratch please, written by yourself (ask instructor if you are stuck), not borrowed from any other sources) that reads in a list of words separated by spaces from a text file, then uses an efficient O(N) algorithm to create the inverted file index (hint: consider the topic of this chapter, consider using a Dictionary/hashtable to help you), and writes this index out to another file or prints it to the screen. Each line of the output file should start with the next word (the words should be listed in alphabetical order, and this sorting does not have to be part of the O(N) runtime complexity, e.g. you can use regular…
- you are to design a printer queue that is responsible for handling the printing requests coming from different users. You have to take into consideration that users have different levels of priorities. Each user has an identification number and a password, in addition to printing priorities. One good idea is to design the queue using an array or pointers while preserving the first-in first-out concept of the queue. For every printing request received, the program should check the priorities of that request and whether it can be moved forward in the queue to be served by the printer prior to serving the other requests. Using the programming language of your choice (preferably C++), write the printer queue that would handle the user request. The program must allow for requests coming from different users or from one user. Note: I need a working C++ code for this problem, and i need priorities.Answer this question please.Write three static comparators for the Point2D data typeof page 77, one that compares points by their x coordinate, one that compares them bytheir y coordinate, and one that compares them by their distance from the origin.
