Exercise 7 has been solved correctly.
Here, I have also attempted to solve exercise 8. However, it is not correct and requires to be changed. Please take a look at it @Tomiyosi-Bola
I am closing this pull request as I went ahead with the Milestone 2 project and corrected Exercise 8 as well. I will create another pull request that will have my corrections from both Exercise 7 and 8.
