- Data structures find_color(colors:set, values:list) -> list The function will have two parameters. The first parameter is a set of strings known as Colors. A second parameter is a list of tuple-2 known as Values. Colors will contain a set of randomly selected colors. Values will contain a list of tuples of size 2. Each tuple will contain color (str) and a number (int). The function should look at each tuple in Values. For each tuple, add the number (the second value in the tuple) to a list of numbers if the color in the tuple (the first value in the tuple) is in Colors. In other words, find all tuples that have a color in the Colors and add the tuples numbers to a list. Finally, the function should return the list of numbers collected in the order they are found in the values list. Example: Colors: {'black', 'pink', 'yellow'} values: [('green', 100), ('yellow', 13), ('red', 6)] Expected: [13] Colors: {'yellow'} values: [('black', 54), ('pink', 5)] Expected: [] Colors: {'black',…C++ Programing Create an application to keep track of a list of students and their grades in a data structures course using a linked list. You should use the C++ STL library. You need to create a class called student that contains 2 data members: name and grade and then create a linked list of objects of this class. The application should allow the user to add a student, remove a student, update the grade for a student, and search for a student.Homework Assignment-1Topics: Functions, Dictionary, ImportProblem description: Write a python application to simulate an online clothing system. Thepurpose of this assignment is to gain experience in Python dictionary structure, create basicPython functions and import a module.Design solution: The template file contains a list of clothes item sold, each item in the listcontains the item id, name of the item and the prices. The program will generate an items_dictwhere each key is the item id of the cloth and the values will be a list of item name and priceinformation. A customer will be presented with a main menu with 4 different options: displayall items, add an item to cart, checkout and exit the program. A customer can buy an item byentering the ID of the item. This program implements a dictionary called cart, where each key isthe item id and the values are the list of name, price and quantity that user chooses topurchase. The program keeps repeating by displaying the main menu to…

The elements in the returned list must be in the same order that they were found in the list the function received. A duplicate element is an element found more than one time in the specified list.
