Create function createPlates() to meet the conditions below:

# - Accepts a list of 3-letter strings, and a list of 4-digit strings
# - add a docstring
# - returns a new list representing all possible combinations of EACH
# - 3-letter string and EACH 4-digit numbers with a dash ('-') in between
# --- Example 1: create_plates(["ZQQ", "AEE"], [1234, 4567])
# --- returns the list ["ZQQ-1234","ZQQ-4567","AEE-1234"," AEE-4567"]
# --- Example 2: create_plates(["ZQQ", "BRP", "AEE"], [1234, 4567])
# --- final list:
# --- ["ZQQ-1234","ZQQ-4567","BRP-1234", "BRP-4567","AEE-1234","AEE-4567"] # - return the result

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 =
