Derek is working with a 230-page master document. Yesterday he autogenerated a table of contents, and today he wrote multiple new paragraphs in different chapters of the document. He also moved some paragraphs from one
chapter to another. However, he did not change any of the chapter titles or any of the subsection headers.
What should Derek do to most efficiently update the table of contents?
O autogenerate a new table of contents
update page numbers only
update the entire table
O manually edit the page numbers

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 =
