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).

Write a new lc-3 trap subroutine (i. e. a subroutine that will be invoked via the trap instruction) that will receive a numeric digit entered at the keyboard (i. e. an ascii character), echo it to the screen, and return in r0 the corresponding numeric value: so if the user types the digit '7', the character '7' will appear on the screen, but the value returned in r0 will be b0000 0000 0000 0111 (#7) you may not use any trap calls in your code - you must implement the "polling" code that interrogates the keyboard status and data registers. ; getnum_tsr ; a subroutine for obtaining a numeric value ; given ascii numeric digit input to keyboard. ; the numeric digit is echoed to the console (e. g. '7' = b0000 0000 0011 0111), ; but the value returned in r0 is the actual numeric value ; corresponding to the digit (e. g. b0000 0000 0000 0111 =
