- 1. Given a global list of users and password like the following, write a function (called login) that takes a user name and password and logs in the user if login is successful:- the user exists in the list- and the password is correct The function should return a True/False users = {'Jane': 'Password123@', 'John': 'Password123!'} 2. Write a function called register that takes a user name and password and adds the user to the list if the user does not already exist in the listThe function should return a True/False Put it all together: 3. Write a showmenu function that shows the following options and reads the choice from user and returns it: 1: register 2: login 0: logout 3. In the main section, based on the user's selected option, ask the required input (user name, passwords) and perform the requested operation. 4. Repeat the above until the user enters 0. (keep showing the menu that asks for another option)Write this program in C programming language. Also provide a screenshot that it is working.Here is the question:Write a program that determines the three largest elements among inputed numbers.Please use C++ Extend and implement the Dynamic Programming Algorithm in the last example of the relevant slides so that it prints a parenthesized expression yielding the goal or “No parenthesization possible.” if no such parenthesization exists. Input format (no need to check its validity): The first line contains a positive integer (say n). The symbols: The second line contains at least n characters (if it contains more, only the first n are relevant). These characters are the symbols of the alphabet. The last symbol is the “goal”. The operation: The following n lines contain at least n characters each (if a line contains more characters, only the first n are relevant). This is an nxn matrix containing the results of the operations. Expression: The last line of the input contains a sequence of characters, consisting of the valid symbols for which you have to seek for a parenthesization. A sample input: 3 abc aac baa caa caaccb and corresponding possible outputs (not exhaustive):…
