Describe how lexical analyzer generators are used to translate regular expressions into deterministic finite automata?

Lexical analyzer generators translate regular expressions (the lexical analyzer definition) into finite automata (the lexical analyzer).
For example, a lexical analyzer definition may specify a number of regular expressions describing different lexical forms (integer, string, identifier, comment, etc.). The lexical analyzer generator would then translate that definition into a program module that can use the deterministic finite automata to analyze text and split it into lexemes (tokens).

What is the difference between 'stochastic' and 'deterministic'?
These words are used to describe ways of modeling or understanding the world. "Stochastic" means that some elements of the model or description are thought of as being random. (The word "Stochastic" is derived from an ancient Greek word for random.) A model or description that has no random factors, but conceivably could, is called "deterministic." For example, the equation Q = VC where Q = charge, V = voltage, and C = capacitance, is a deterministic physical model. One stochastic version of it would be Q = VC + e where e is a random variable introduced to account for or characterize the deviations between the actual charges and the values predicted by the deterministic model.

Describe how multiplication and division of rational expressions can be done?
Suppose X1 = N1/D1 and X2 = N2/D2 are two rational expressions, where the numerators N1 and N2 and denominators D1 and D2 are simpler expressions. Then X1 * X2 = (N1*N2)/(D1*D2) and X1 / X2 = (N1*D2)/(D1*N2).

What you think is you theme of lesson on the face explain?
The theme of a lesson on the face could be understanding facial features, expressions, and emotions. Students could learn how to identify and describe different facial features, interpret emotions based on facial expressions, and explore the role of the face in nonverbal communication.
