Question
Consider the following sequence of tokens: not 4 Select true or false for each of the following statements about the given sequence of tokens: It is an invalid atomic expression because it does not start with an identifier token or a literal token or a keyword reference token fTrue, False, None, or a parenthesis. It is an invalid binary expression because a binary expression requires at least three tokens. It is an atomic expression. The first token in the sequence is a keyword token, which is being used as a unary operator token. It is a unary expression. The second token in the sequence matches a path from the start state to the identifier token terminal accepting state Choose Choose.. | Choose...- Choose Choose Choose...Explanation / Answer
Given sequence of tokens - not 4
It is an invalid atomic expression because it does not start with an identifier token or a literal token or a keyword reference token {True, False, None}, or a parenthesis. - TRUE
It is an invalid binary expression because a binary expression requires at least three tokens.- TRUE
It is an atomic expression. - FALSE
The first token in the sequence is a keyword token, which is being used as a unary operator token. - TRUE
It is a unary expression. - TRUE
The second token in the sequence matches a path from the start state to the identifier token terminal accepting state. - FALSE
The simplest form of expression is called an atomic expression. - TRUE
A transition is represented by an arrow in the syntax diagram and the direction of the arrow defines the path through the diagram. - TRUE
Start state, terminal state, non-terminal state and accepting state are kinds of states that are parts of a syntax diagram. - TRUE
If state is part of a syntax diagram, and transition is part of a syntax diagram, then we can infer that transition is part of a state. - FALSE
A state that represents a single token from a set of tokens is called a non-terminal state. - FALSE
A state that does not represent a single token from a set of tokens is called a terminal state, and requires its own syntax diagram. - FALSE
