Computer Science must be in c++ 1. Write a program that can extract the duplicate names of a file using the set template class. A file with duplicate names (duplnames.txt) is read and each line is entered into a set.

1. The codewords will be scrambled words. You will read the words used for the codes from a file and store it into an array. There are 60 words in the file that range in size from 3 characters to 7 characters. The file is called wordlist.txt and can be found attached to the assignment in IvyLearn.2. Start with input for an integer seed for the random number generator. There is no need to put a prompt before the cin operation.3. Ask the Player if they are ready to play and only proceed if they type a Y or y. If the user types an N or n then the program should finish. a. INPUT VALIDATION: Make sure the user has typed either y, Y, n, or N4. Create a variable to keep track of the number of guesses the user has made.5. Use the random number generator to pick a word from the list of words.6. Once you have chosen a word as the codeword you will need to scramble the letters to make it into a code. You should use the random number generator to help you mix up the letters.7. Display to the user…

Suppose names is an ABList containing 10 elements. The call names.add(0, "George") results in: A. an exception being thrown. B. a 10-element list with "George" as the first element. C. an 11-element list with "George" as the first element. D. a single element list containing "George". E. None of these is correct.

Filename: runlength_decoder.py Starter code for data: hw4data.py Download hw4data.py  Download hw4data.pyYou must provide a function named decode() that takes a list of RLE-encoded values as its single parameter, and returns a list containing the decoded values with the “runs” expanded. If we were to use Python annotations, the function signature would look similar to this:def decode(data : list) -> list: Run-length encoding (RLE) is a simple, “lossless” compression scheme in which “runs” of data. The same value in consecutive data elements are stored as a single occurrence of the data value, and a count of occurrences for the run. For example, using Python lists, the initial list:     [‘P’,‘P’,‘P’,‘P’,‘P’,‘Y’,‘Y’,‘Y’,‘P’,‘G’,‘G’] would be encoded as:     ['P', 5, 'Y', 3, ‘P’, 1, ‘G’, 2] So, instead of using 11 “units” of space (if we consider the space for a character/int 1 unit), we only use 8 “units”.  In this small example, we don’t achieve much of a savings (and indeed the…
