Expert Solution & Answer
Chapter 4, Problem 16RQ
Explanation of Solution
FIRST set for a given grammar and sentential form:
We can define FIRST for a non-terminal A in a grammar as a set which contains terminals that can occur as the first terminal symbol in a string which is derivable from A. FIRST is computed based on the RHSs of the non-terminal in the given grammar...
