Аз си ходя на лекции. А това за идентацията няма да го коментирам...

Всъщност ще го коментирам...

Не че незнам как трябва да го идентирам Ходя на работа по 9 часа на ден и през цялото време си пиша така, като дойда събота сядам да си го направя това домашно, и като почна да спазвам тази Ruby идентация, която искате,кода ми става супер нечетими ми и НЕпрегледен и ми отнема 2-пъти повече време. Ако имам времем след като напиша домашното ще го форматирам, ако нямам - взимаите ми точки
