Story of a bug

Debugging is of course a major part of programming. Arguably most of the time it’s not the most satisfying part of the job, it’s an unfortunate necessity rather than the goal itself. Moreover, I think that most of the bugs I make aren’t interesting (e.g. typos, wrong usage of a library function, nullptr dereferences, off-by-one errors etc.).

Wyra┼╝enia regularne a algorytm Floyda-Warshalla

Kr├│tka notatka o fajnym po┼é─ůczeniu mi─Ödzy dwoma ┼Ťwiatami

Na jednych z pierwszych zaj─Ö─ç JFiZO zosta┼é przedstawiony konstruktywny dow├│d na r├│wnowa┼╝no┼Ť─ç si┼éy wyra┼╝e┼ä regularnych oraz deterministycznych automat├│w sko┼äczonych (DFA). Pokazanie, ┼╝e dla ka┼╝dego regexa istnieje r├│wnowa┼╝ny DFA jest proste, sprawa komplikuje si─Ö w drug─ů stron─Ö. Tak mi si─Ö przynajmniej na pocz─ůtku wydawa┼éo, ale im d┼éu┼╝ej o tym my┼Ťla┼éem, tym bardziej odczuwa┼éem wra┼╝enie, ┼╝e gdzie┼Ť ju┼╝ ten dow├│d widzia┼éem.

Tutaj mo┼╝na sobie zobaczy─ç moje notatki z JFiZO i nie tylko.
