Write a program in a lc-3 simulator use assembly language:

the program should accept an ascii character string, terminated by a carriage return. Echo the characters as they are typed in, then, on a new line, print out the string in reverse. Implement your program using a stack, by writing Push and Pop subroutines and calling them to do the work. The test string will not be longer than 40 characters. You do not need to handle a stack overflow condition.

Sample input: Reverse This String...

Desired Output: ...gnirtS sihT esreveR

If user tries to enter more than 40 characters, stack overflow is detected by the PUSH subroutine and the message "stack overflow" is displayed after echoing the 40 characters entered before the stack overflow event.
