Write a assembly program that performs a reflex test. First the program displays a greeting message (e.g. "This is a reflex test program. When displays „push a key now!”, press a key as fast as you can. Press a key to start it."). After it the program displays "press a key now" and it stores the elapsed time between displaying the text, and pushing a key. Than it repeats 9 times (displays the sentence again under the previous string, in the next line), and summarize the time peroids. After it, the program displays the value, and rate the user speed: For example: 0-40 -> „excellent”, 41-80 -> „very good”, … 160-200 -> „it sholud be better", aobve 200 -> „too slow!”

use this as a base code:
