Exercise 4.2.3: Design grammars for the following languages: a) The set of all strings of 0 s and 1 s such that every 0 is immediately followed by at least one 1 .

Answers

Answer 1

To design a grammar for the set of all strings of 0s and 1s such that every 0 is immediately followed by at least one 1, we need to start by defining the language's rules.


Let's start with the basic elements of the language: 0s and 1s. We can define them as terminals in our grammar, represented by the symbols '0' and '1.'

Next, we need to define the rules for constructing strings in our language. We want to ensure that every 0 is immediately followed by at least one 1. We can accomplish this by creating a rule for constructing a sequence of 0s and 1s.

Our grammar could look something like this:

S -> 0T | 1S
T -> 1S | 0T

Here, S is the start symbol, and T is a nonterminal symbol used to generate a sequence of 0s and 1s. The first rule for S says that we can start with a 0 and then generate a sequence using T, or we can start with a 1 and generate a sequence using S. The rule for T says that we can add a 1 and generate a new sequence using S, or we can add another 0 and generate a longer sequence of 0s followed by 1s.

Using this grammar, we can generate strings like "101," "1001," "10001," and so on, but we cannot generate strings like "110" or "001" since they violate the rule that every 0 must be immediately followed by at least one 1.

In conclusion, designing a grammar for a language that only includes strings of 0s and 1s such that every 0 is immediately followed by at least one 1 requires defining rules that ensure the proper sequence of symbols. By using nonterminal symbols to generate sequences of 0s and 1s, we can create a grammar that generates only valid strings in this language.

Answer 2

To design a grammar for the set of all strings of 0s and 1s such that every 0 is immediately followed by at least one 1, we can use the following rules:

S → 0A | 1S | ε

A → 1S

Here, S is the start symbol, and A is a non-terminal symbol that helps enforce the constraint that every 0 must be followed by at least one 1.

The rules can be read as follows:

S can produce either a 0 followed by A (which will produce a 1), or a 1 followed by S, or nothing (ε).

A must produce a 1 followed by S.

Starting with S and applying the rules, we can generate strings in the language as follows:

S → 0A

S → 01S

S → 011S

S → 0111S

...

This generates strings such as "0111", "01011", "001111", etc. which satisfy the condition that every 0 is followed by at least one 1.

I need help writing the algorithm I know how to do the flow chart for the first one but I’m not sure if the second question is a for loop

Answers

Answer:

The algorithm is as follows:

(a) Sales and commission

1. Start

2. Input Sales

3. Commission = 0.30 * Sales

3. If sales >= 4000.00 then

3.1   Commission = 0.60 * Sales

4. End If

5. Print Commission

6. Stop

(b) Amount of Rainfall

1. Start

2. Days = 1

3. Total = 0.0

4. While Days <= 31

4.1. Input Rainfall

4.2. Total = Total + Rainfall

4.3. Days = Days + 1

4.4. End If

5. Print Total

6. Stop

See attachment for flowchart

Explanation:

(a) Sales and commission

This begins the algorithm

1. Start

This gets sales from the user

2. Input Sales

This calculates the commission based on 30% (i.e. for sales < 4000)

3. Commission = 0.30 * Sales

This checks if sales is greater than or equal to 4000

3. If sales >= 4000.00 then

This calculates the commission as 60% of Sales

3.1   Commission = 0.60 * Sales

This ends the if condition

4. End If

This prints the calculated commission

5. Print Commission

This ends the algorithm

6. Stop

(b) Amount of Rainfall

This begins the algorithm

1. Start

This initializes the number of days to 1

2. Days = 1

This initializes total rainfall to 0

3. Total = 0.0

The following while loop is repeated until day 31st

4. While Days <= 31

This gets input for Rainfall from the user

4.1. Input Rainfall

This calculates the total rainfall

4.2. Total = Total + Rainfall

This increments the number of days

4.3. Days = Days + 1

This ends the if statement

4.4. End If

This prints the total rainfall

5. Print Total

This ends the algorithm

6. Stop

Coke has experimented with different formulations of its popular Coca Cola product, including the failed New Coke iteration. The aim is to achieve the best tasting product that customers like.

A company that is operating a factory or assembly line may experiment with different methods of arranging the assembly line or with different production methods. Each time the production process is changed, this is a different iteration. Each time the order of operations and procedures are changed, this is a different iteration. The goal is to achieve the fastest, best and most optimal method of creating a product.

A musician may start with one version of a song and refine it, making changes to a note here and there or changing the tempo and speed. Many different iterations of a song may be created this way until the optimal finished product has been created that sounds and works the best.

A cook may experiment with a recipe, tweaking the ingredients or changing different steps of the process slightly until the food tastes as good as it possibly can.

Answers

Answer:

Rapid Application Development (RAD)

Explanation:

Software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications.

RAD is an acronym for rapid application development and it is a model that is typically based on the concepts of prototyping and iterative development technique with minimal documentation or planning involved.

In the RAD model, more priority is given to the development of the software while minimal attention is given to documentation or planning. Therefore, it focuses on developing softwares within a short period of time and using prototypes (working modules) such as templates, codes, processes, tools, etc.

Basically, the RAD model comprises of five (5) phases and these includes;

I. Business modeling.

II. Data modeling.

III. Process modeling.

IV. Application generation.

V. Testing and turnover.

In conclusion, the RAD model allows software application to be delivered with a demo of the working software at every stage of development for continuous customer interaction.

Explanation:

The schematic diagram below shows three machines in a production unit connected to a 240 volt supply.
The layout uses different types of wire for the main wire, wire 1, wire 2, and wire 3.
Calculate the maximum current that can flow through each type of wire. The diameter of a wire is related to the maximum amount of current it
can safely carry. Use Internet resources to find the most suitable gauge of wire for each part of the wiring in the circuit. List the highest American
Wire Gauge (AWG) number that you can use for each type of wire. (Hint: For the main wire, consider how the current through it relates to the
currents through each of the machines.)
Also, state how you can protect the wiring from damage If any of the machines exceeds its maximum power rating because of a malfunction.

Answers

Answer:

[tex]\begin{array}{ccc}Wire \ Number &Maximum\ \ Current \ (A)& AWG\\&&\\Main \ Wire&16\frac{5}{6} &9\\&&\\Wire \ 1&9\frac{1}{6} &12\\&&\\Wire \ 2&5&14\\&&\\Wire \ 3&2.5&17\end{array}[/tex]

Explanation:

The given parameters of the circuit are;

The voltage applied to the circuit = 240 volt

The types of wire in the circuit are Main wire, wire 1, wire 2, and wire 3

The maximum current that can flow through each type of wire is given by the max power of the machine powered by the wire

Power, P = Voltage, V × Current, I

∴ I = P/V

The maximum power of the machine powered by wire 1 = 2,200 W

The current flowing through wire 1, I₁ = 2,200 W/(240 V) = 55/6 A = [tex]9\dfrac{1}{6} \, A[/tex]

The maximum power of the machine powered by wire 2 = 1,200 W

The current flowing through wire 2, I₂ = 1,200 W/(240 V) = 5 A

The maximum power of the machine powered by wire 3 = 600 W

The current flowing through wire 3, I₃ = 600 W/(240 V) = 2.5 A

Therefore, Kirchhoff's current law, we have;

The current that the main wire can carry, I = I₁ + I₂ + I₃

∴ I = 55/6 A + 5 A + 2.5 A = 50/3 A = 16.[tex]\overline 6[/tex] A

The current that the main wire can carry, I = 16.[tex]\overline 6[/tex] A

The highest American Wire Gauge (AWG) that can be used for each type of wire are listed as follows;

[tex]\begin{array}{ccc}Wire \ Number &Maximum\ \ Current \ (A)& AWG\\&&\\I&16\frac{5}{6} &9\\&&\\I_1&9\frac{1}{6} &12\\&&\\I_2&5&14\\&&\\I_3&2.5&17\end{array}[/tex]

Therefore, we have;

[tex]\begin{array}{ccc}Wire \ Number &Maximum\ \ Current \ (A)& AWG\\&&\\Main \ Wire&16\frac{5}{6} &9\\&&\\Wire \ 1&9\frac{1}{6} &12\\&&\\Wire \ 2&5&14\\&&\\Wire \ 3&2.5&17\end{array}[/tex]
