Consider a dash system for which there are n video versions (at n different rates and qualities) and n audio versions (at n different rates and qualities). suppose we want to allow the player to choose at any time any of the n video versions and any of the n audio versions. a. if we create files so that the audio is mixed in with the video, so server sends only one media stream at given time, how many files will the server need to store (each a different url)? b. if the server instead sends the audio and video streams separately and has the client synchronize the streams, how many files will the server need to store?

This program reads a file called 'test. txt'. you are required to write two functions that build a wordlist out of all of the words found in the file and print all of the unique words found in the file. remove punctuations using 'string. punctuation' and 'strip()' before adding words to the wordlist. write a function build_wordlist() that takes a 'file pointer' as an argument and reads the contents, builds the wordlist after removing punctuations, and then returns the wordlist. another function find_unique() will take this wordlist as a parameter and return another wordlist comprising of all unique words found in the wordlist. example: contents of 'test. txt': test file another line in the test file output: ['another', 'file', 'in', 'line', 'test', 'the']
