Expert Solution & Answer
Chapter 4, Problem 3RQ
Explanation of Solution
Lexemes:
The input to the lexical analyzer is a sequence of characters (a long string) from which the analyzer identifies a substring which matches with a valid pattern. That is, it collects the characters and groups them into logical groups according to the pattern matching rules. These logical groupings are called as lexemes...
