Problem $3$: Write an ARMv$7$ assembly program that reverses a given list of integer value which terminates with $0.$

Requirements:

$1.$ Assume the input list is stored in memory, starting at a label called $`$input$\_$list$`.$

$2.$ The list is terminated by $0$ at the end.

$3.$ The program must reverse the list in memory $($e$.$g$.,1,2,3,4,5,0$ will become $\backslash (5,4,3,2,1,0\backslash ))$

$4.$ Use a loop and LDR$/$STR command to accomplish the reversal.

$5.$ Assume the only zero value will be end of this list

Example:

Define the list in the memory like this: input$\_$list dcd $1,2,3,4,5,6,7,0$

After this line the memory should look something like this:

Extra Credit Assignment

After reversing this above list the memory should something like below:

Here you can see that the list list is now reserved in the same memory location for the input$\_$list.

Hints:

$-$ Use a register to point to the start of the string.

$-$ Use another register to find the end of the string by searching for the $0.$

$-$ Swap characters from the start and end of the string until they meet in the middle.

$-$ Ensure your program exits cleanly after completing the reversal.
