Using Stack Automatons for String Matching
1:28:50 - 1:40:50 (11:59)
The stack automaton is introduced as a machine that recognizes a language where the strings of the language are of length n in any amount of time. It is explained that this automaton can solve certain string matching problems efficiently while regular computers struggle with them.
