Which of the following is top-down parser Mcq?
Which one of the following is a top-down parser? Explanation: Recursive Descent also known as top down parsing also known to be LL(1).
Which of the following is top-down parsing?
Recursive descent parsing is an example of top-down parsing.
Which of the following is a top-down parser operator precedence operator shift reduce parser recursive descent parser LR K parser?
(C) An LR(k) parser. Explanation: Recursive Descent parsing is LL(1) parsing which is top down parsing.
What does a top-down parser generates?
The top-down parser is the parser that generates parse for the given input string with the help of grammar productions by expanding the non-terminals i.e. it starts from the start symbol and ends on the terminals. It uses left most derivation.
Which of the following is top down approach Mcq?
Explanation: Product design is top down approach.
What is top down approach Mcq?
Solution(By Examveda Team)
Top down approach is used for development. A top-down approach (also known as stepwise design and in some cases used as a synonym of decomposition) is essentially the breaking down of a system to gain insight into its compositional sub-systems in a reverse engineering fashion.
Which of the following is top-down approach?
The top-down approach to management is one such strategy, in which the decision-making process occurs at the highest level and is then communicated to the rest of the team. This style can be applied at the project, team, or even the company level, and can be adjusted according to the particular group’s needs.
Is used in top-down parsing Mcq?
Top down parser uses the left most derivation to generate the string. Semantic analysis: Semantic analysis is the task of ensuring that declarations and statements of a program are semantically correct. For this, it uses type casting.
What is top-down parsing explain the limitations of top-down parser?
The process of constructing the parse tree which starts from the root and goes down to the leaf is Top-Down Parsing. Top-Down Parsers constructs from the Grammar which is free from ambiguity and left recursion. Top-Down Parsers uses leftmost derivation to construct a parse tree.
What are the different types of top-down parsing techniques?
Some of the parsers that use top-down parsing include:
- Definite clause grammar parsers.
- Recursive descent parser.
- Predictive parser.
- Earley parser.
How many types of parsing are there Mcq?
The way the production rules are implemented (derivation) divides parsing into two types : top-down parsing and bottom-up parsing.
What is top-down parsing in automata?
In top-down parsing, the parse tree is generated from top to bottom, i.e., from root to leaves & expand till all leaves are generated. It generates the parse tree containing root as the starting symbol of the Grammar. It starts derivation from the start symbol of Grammar & performs leftmost derivation at each step.
Which derivation is generated by the bottom-up parser Mcq?
right-most derivation in reverse
Explanation: A bottom-up parser generates right-most derivation in reverse.
Which of the following method is top-down method for nanomaterials Mcq?
Which of the following is an example of top-down approach for the preparation of nanomaterials? Explanation: Mechanical grinding is an example of top-down approach for the preparation of nanomaterials.
Which of the following is true about top-down design process Mcq?
Which of the following is true about top-down design process? Explanation: Top-down design is an approach for deriving a modular design in which the overall design.
Which one of the following is top-down approach in nanomaterial preparation?
Explanation: mechanical grinding is an example of top-down approach for the preparation of nanomaterials.
Which of the following approaches is also known as the bottom-up approach Mcq?
B. C. D. Explanation: colloidal dispersion is an example of bottom up approach in the synthesis of nano particles.
Which of the following is a top-down approach to design a database?
A top down approach is used to create a new database. You model the objects at a logical level, then you apply the objects to a physical database design. For example, a relational database would need the objects to be mapped to tables.
Which of the following Cannot be a structure member Mcq?
Which of the following cannot be a structure member? Explanation: None.
What are the disadvantages of top-down approach?
Disadvantages of the top-down approach include: Low participation (this is likely to influence the implementation of the plans in a negative way). Requires a lot of knowledge at the top level. Does not use specialized knowledge which may be present in the lower echelons of the organization.
