Expert Solution & Answer
Chapter 4, Problem 22RQ
Explanation of Solution
Mathematical machine on which both top-down and bottom up parsers:
- PDA can be considered as a mathematical machine which scans the input symbols from left to right.
- Since it uses a pushdown stack as the memory and hence the name.
- PDA is used to recognize languages of a context free grammar. That is it can determine whether the input string is a sentence of the context free language...
