А това дето викаш че не работи даже с примера е странно, помня че го тествах и работеше преди да го кача. 🤔

Хах ами дискретните не са ми сила ама изобщо и учих regex-и от вашата презентация за точно един цял ден. Та няма какво да се очаква XD. То и сега съм на ски и не мога да го видя да го оправя. Като се върна в софия ще го погледна защо не работи.

Много ми се иска и на теб да дам бонус точка, но на другите с фейлващи тестове им липсва някоя скоба, някой интервал. При теб прекарах 10-тина минути да фиксвам _(не да го пренаписвам, това убива смисъла в упражнението)_ и пак е трудно да се доближа до коректен match. Некст гейм е некст гейм, дет' вика Ицата...

То даже с примера не работи, буквално всеки път връща празен списък. ;(

Утре ще се опитам да го докарам до one liner :^)
