A two-dimensional array myArray is to be created with the following contents. {{0, 0, 3},

{0, 0, 0},

{7, 0, 0}}

Which of the following code segments can be used to correctly create and initialize myArray ?

I. int myArray[][] = new int[3][3];
myArray[0][2] = 3;
myArray[2][0] = 7;

II: int myArray[][] = new int[3][3];
myArray[0][2] = 7;
myArray[2][0] = 3;

III: int myArray[][] = {{0, 0, 3}, {0, 0, 0}, {7, 0, 0}};

A) I only.

B) II only.

C) III only.

D) I and III.

E) II and III.

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 =
