30.1 Problem

In this exercise your job is to write a terminal based application that measures your (touch) typing speed. The end result should resemble the one presented in the GIF below.

Your program should:

• mark the characters (in)correctly typed
• allow to delete the (incorrectly) typed characters
• display some basic summary of the speed (like WPM - words per minute)

To make it easier, you may assume it to always operate on a short line of text (let’s say up to 50 characters long) composed only of the characters from the standard Latin alphabet encoded by ASCII.
