Question

- Given a sample sentence and an explanation of its language, produce a BNF grammar for the language.
- Convert a BNF grammar into an EBNF grammar.

Answer #1

The example of a language sentence and bnf is given as follows:

Example:

Sample sentence:

K1N 6N5 M5W 2E4 X0A 1A1

BNF for the sample:

<postalcode> ::= <letter> <number> <letter> <number> <letter> <number>

To convert from BNF to EBNF:

Extended Backus-Naur form (EBNF) is a collection of extensions to Backus-Naur form.

Changing from BNF to EBNF require different rules for different types but the for the above simple example the EBNF remains the same.

Convert an example EBNF grammar into a BNF grammar. For an
example BNF grammar, determine if it is ambiguous.Rewrite an
ambiguous grammar so that it is unambiguous.

Write a BNF grammar for a new language called 4040. It should
include the following rules:
Variable definitions should start with var.
There must be only single space after var.
Variable names should come after the var and single space.
Variable names should start with a letter or underscore(_).
Starting with a digit is not allowed.
Variable names can have digits after the first letter.
There can be multiple variable names separated by comma.
Between variables, spaces are allowed.
There...

For the given language descriptions below, write a context-free
grammar.
Assume that your alphabet is ∑ = {?, ?, ?}, define a grammar
that generates a string
cmanbanck, where ‘m’,
‘k’, and ‘n’ represents the amount of a character. Assume that m, k
≥ n and m, k, n ≥ 0.

Using R programming language, complete the following.
1. Generate the bivariate normal sample of size 100 with
parameters
a. marginal mean of X equal to 1,
b. marginal mean of Y equal to 2,
c. marginal variance of X equal to 3,
d. marginal variance of Y equal to 4,
e. correlation between X and Y equal to -1/2.
You can use the function mvrnorm(), first installing its package by
the code

There is a design methodology called rapid prototyping,
which has been used successfully in software engineering.
Given similarities between software design and instructional
design, we argue that rapid prototyping is a viable method for
instructional design, especially for computer-based
instruction.
