Design a DFA that differentiates between valid identifiers and keywords in a programming language. The DFA should accept identifiers that start with a letter or underscore, are followed by letters, digits, or underscores, while keywords like 'if', 'else', and 'while' are always accepted as keywords.
💡 Hint: Consider how to structure the states for keywords and identifiers distinctly.
Create a detailed transition diagram for a DFA that recognizes the pattern of a floating-point number, which includes an optional sign, digits before a decimal, a decimal point, and digits after the decimal.
💡 Hint: Make sure to account for optional signs and the decimal point in your transition diagram.
