Solve the following in C## Run Length Encode Manytimes,certaindatafiletypescanconsistoflarge amounts of repeated data. For instance, images can have large runs of the same color. This can be easily compressed using a technique called run length encoding. With run length encoding, large amounts of repeated data are stored as the repeated data and the number of times to repeat it. CreateaclassRunLengthEncodethatcontainsthemethod encode which takes one argument: a String to be encoded as described below. ThereturnvalueshouldbeaStringwhichhasbeenencoded with the following algorithm: Ifanycharacterisrepeatedmorethan4times,theentire set of repeated characters should be replaced with a slash '/', followed by a 2-digit number which is the length of the set of characters, and the character. For example, "aaaaa" would be encoded as "/05a". Runs of 4 or less characters should not be replaced since performing the encoding would not decrease the length of the string. Notes Letters are…

Computer Science Assume you are part of a project to develop a novel customized online standalone chatting application for a company. The chat is supposed to support text, audio, video messages; it is also intended to support video and audio streaming. Your role in the project is to coordinate the networking team (efficient data transmission). Other teams handle other parts, such as interface and video capture. Your team's target is also to create your own proprietary library, not relying on other proprietary or open libraries, except the socket API. (i) Describe the structure of your application in general. Will it be a client-server or P2P application? How do clients find the server or each other? Do clients need to connect to the server or each other? (ii) What type(s) of sockets do you need to use in your application? Justify your answer and give example(s). (iii) Do chat media require reliable, in-order packet transfers? If yes, which types of media from the description need it?…

API Actions: - Create a wishlist of books that belongs to user. The books must haveunique names- Add a book to a user’s wishlisht- Remove a book from a user’s wishlist and place a book into the user’sshopping cart- List the book in a user’s wishlist

Computer Science Can someone help me create a program that is a library management system? So, the program will manage a library collection of books, allowing the user to add books, check them out, and return them. possibly use data structures such as linked lists or hash tables which will keep track of the availability of the books. demonstrate its function and discuss your experiences in creating it. Topics worthy of discussion include details of the implementation itself (language choice, class design, etc), difficulties that you faced in implementing it (learning new techniques, significant errors encountered, etc), and maybe a project post-mortem discussing whether or not you would do anything differently, knowing what you do about it at the end (e.g. using a linked list instead of an array). c++
