Romil is practising his typing skills since his current typing speed is very low. He uses a training application that displays some words one by one for Romil to type. When typing a word, Romil takes 0.2 seconds to type the first character; for each other character of this word, he takes 0.2 seconds to type this character if it is written with a different hand than the previous character, or 0.
