In the second part of your project, you need to develop a mathematical worksheet graphical interface for elementary school students. The worksheet consists of 10 questions of operations between two random numbers. The operations are defined randomly from the set {+, -, *, /}. The GUI uses a text field to enter the maximum value of random numbers. A button with the caption "Check Answers" should be added to the GUI, and when clicked, a correct icon () should appear in front of the correct answer and an incorrect icon

- switch_player(): we will allow the players to choose their own names, but for our purposes, it is easier to think of them as number (0 and 1, for indexing purposes). We will display their names to them on the screen, but in the background, we will keep track of them based on their number. This function should take 1 argument, an integer (either 0 or 1) representing the player and should return the opposite integer (1 if 0 is entered and 0 if 1 is entered). This is a simple function, but it will make our code cleaner later. Use your constants!
