1. A problem can be solved recursively if it can be broken down into successive smaller problems that are unique within the overall problem. a. True
b. False

2. It always is possible to replace a recursion by an iteration and vice versa.
a. True
b. False

3. A recursive method without a base case leads to infinite recursion.
a. True
b. False

4. Since iterative solutions often use loop variables and recursive solutions do not, the recursive solution is usually more memory efficient (uses less memory) than the equivalent iterative solution.
a. True
b. False

5. Some problems are easier to solve recursively than iteratively.
a. True
b. False

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 =
