CS1-FULL-FALL2021 459 Sorting 460 why study sorting? Sorting is a classic subject in computer science. There are three reasons for studying sorting algorithms. • First, sorting algorithms illustrate many creative approaches to problem solving and these approaches can be applied to solve other problems. • Second, sorting algorithms are good for practicing fundamental programming techniques

Slide 1 Algorithms and Decision Procedures for Context-Free Languages Chapter 14 Decision Procedures for CFLs Membership: Given a language L and a string w, is w in L? Two approaches: ● If L is context-free, then there exists some context-free grammar G that generates it. Try derivations in G and see whether any of them

Slide 1 Pushdown Automata Chapter 12 We need a device similar to an FSM except that it needs more power. The insight: Precisely what it needs is a stack, which gives it an unlimited amount of memory with a restricted structure. Example: Bal (the balanced parentheses language) (((())) Recognizing Context-Free Languages Definition of a Pushdown
