Program Plan Intro
Sets:
- • In Python, a set is defined as an unordered collection of unique data.
- • No two elements in the set can have same value.
- • The data type of each element can be different.
- • Set is a mutable object since elements can be added or removed from the set.
- • Each element in the set is immutable, which means it cannot be changed.
- • Use of indexing elements in the set cannot be accessed.
Method “union()”:
- • The union of two sets creates a set that contains the members of both the sets.
- • The “union” method in Python is called to find the union of two sets.

- Scrambled Codewords C++ 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. Start with input for an integer seed for the random number generator. There is no need to put a prompt before the cin operation. 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. INPUT VALIDATION: Make sure the user has typed either y, Y, n, or N Create a variable to keep track of the number of guesses the user has made.

Note: Save text below as the file to use and name it forChap12.txt file for this assignment. Text: No one is unaware of the name of that famous English shipowner, Cunard. In 1840 this shrewd industrialist founded a postal service between Liverpool and Halifax, featuring three wooden ships with 400-horsepower paddle wheels and a burden of 1,162 metric tons. Eight years later, the company's assets were increased by four 650-horsepower ships at 1,820 metric tons, and in two more years, by two other vessels of still greater power and tonnage. In 1853 the Cunard Co., whose mail-carrying charter had just been renewed, successively added to its assets the Arabia, the Persia, the China, the Scotia, the Java, and the Russia,…arrow_forwardFinding the common members of two dynamic arrays: Write a program that first reads two arrays and then finds their common members (intersection). The program should first read an integer for the size of the array and then should create the two arrays dynamically (using new) and should read the numbers into array1 and array2 and then should find the common members and show it. Note: The list of the common members should be unique. That is no member should be listed more than once. Tip: A simple for loop is needed on one of the arrays (like array1) and one inner for loop for on array2. Then for each member of array1, if we find any matching member in array2, we record it. Sample run: Enter the number of elements of array 1: 7 Enter the elements of array 1: 10 12 13 10 14 15 12 Enter the number of elements of array 2: 5 Enter the elements of array 2: 17 12 10 19 12 The common members of array1 and array2 are: 12 10arrow_forwardPyhton code please help, indentation would be greatly appreciatedarrow_forward
