*This must be completed using PEP8 code.

The purpose of these exercises is to give you practice of the following:

• mnemonics and labels
• .EQUATE (constant)
• trace tags (practice using these in EACH program)

You will recognize these programs, they are taken from Test1, but now you need to do them in assembly language, using symbols and trace tags. Also use .equate where necessary.

1. Write a program to input three characters and output them in reverse (so if the input is pat, the output will be tap) DO NOT leave spaces in the input, if you do pep8 will take the space as the second character.
2. Write a program to input an integer. Add 2 to the number and output the result. Use .EQUATE for the 2.
3. Write a program to input a string of three lowercase characters and output a string of these characters in uppercase. For example, if the input is abc, output will be ABC. Use .EQUATE for the constant you need to subtract
4. Input two decimal numbers and then subtract the second from the first. Output the result.
