Expert Solution & Answer
Chapter 4, Problem 5RQ
Explanation of Solution
Three building approaches of a lexical analyzer:
The main function of a lexical analyzer is to separate tokens from the input program and to check it syntax validity. The three main approaches to build a lexical analyzer are:
- As lexical analysis involves pattern matching, patterns of the tokens are to be formally described using a language related to regular expression. These formal descriptions for patterns are inputted to an automated software tool which generates a lexical analyzer.
- The second approach is to design a state transition diagram which describes the token patterns...

Contrast the application of a normalized histogram. Is it okay to have a normalized histogram but not its non-normalized counterpart?
