It is well documented that it is physically impossible for a college student to have enough time to get good grades, have a social life, and get enough sleep: at most two of the three goals can be achieved. therefore, any student that does appear to have all three things must be using dark magic. write a function wizards(grades, life, sleep) that takes in three lists of student names (strings), where grades represents students who get good grades, life represents students who have a social life, and sleep represents students who get enough sleep. you can assume that all lists are in alphabetical order. the function must return a list of all students who are clearly wizards (because they appear in all three lists).
