Create a program that simulates a slot machine. When the program runs, it should do the following:

1. Asks the user to enter the amount of money he or she wants to enter into the slot machine.

2. Instead of displaying images, have the program randomly select a word from the following list:

Cherries, Oranges, Plums, Bells, Melons, Bars

To select a word, the program can generate a random number in the range of 0 through 5. If the number is 0, the selected word is Cherries, if the number is 1, the selected word is Oranges, and so forth. The program should randomly select a word from this list three times and display all three of the words.

3. If none of the randomly selected words match, the program informs the user that he or she has won $0. If two of the words match, the program informs the user that he or she has won two times the amount entered. If three of the words match, the program informs the user that he or she has won three times the amount entered.

4. The program asks if the user wants to play again. If so, these steps are repeated. If not, the program displays the total amount of money entered into the slot machine and the total amount won.

In addition, there are two additional requirements.

1. Create a UML diagram for the program.

2. Provide a list of tests to prove that the program works correctly. There should be at least 8 test cases.
