Identify possible objects in the following system and develop an object-oriented design for them. You may make reasonable assumptions about the systems when deriving the design. A group calendar and time management system is intended to support the scheduling of meetings and appointments across a group of co-workers. When an appointment is to be made that involves a number of people, the system finds a common slot in each of their schedules and arranges the appointment for that time. If no common slots are available, it interacts with the user to rearrange his or her personal schedule to make room for the appointment.

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']

Design a pos circuit that displays the letters a through j on a seven-segment indicator. the circuit has four inputs w, x, y, and z which represent the last 4 bits of the uppercase ascii code for the letter to be displayed. thus, if wxyz = 0001 then "a" will be displayed. (any answer with 22 or fewer gates and inverters, not counting any for the inputs, is acceptable)
