You are correct, it has the same functionality. Perhaps the instructor just wanted to include the exercise, for example, as we, as beginners, were invariably asked to code the function max(), even though it is available as a builtin. Perhaps they wanted to leave room for some additional functionality in the future (maybe a log of deleted nodes, I don’t know… )
