Explanation:

Design Pattern

Design Pattern is defined as how the structure is coded across design - functionality , data abstraction , and leaving space for the future inclusions.

The future inclusions are the business logic which are subjected to change .

DLL - is the interface similar named in java language which specifies the contract of what the product or code is going to perform without exposing the underlying complexities of the implementation .

Example :

Calculator is an example of DLL class which contains - add , multiply, subtract , divide methods. The implementation class implements the calculator and write the implementation of the add, multiply methods.

There can be another class that implements this calculator contract and implement scientific calculation logic. In this way you have different choices or flavors of the same contract .

How to write a program that prompts the user to input two POSITIVE numbers — a dividend (numerator) and a divisor (denominator).

fomenos

Answer:

num1 = int(input("Numerator: "))

num2 = int(input("Denominator: "))

if num1 < 1 or num2<1:

print("Input must be greater than 1")

else:

print("Quotient: "+str(num1//num2))

print("Remainder: "+str(num1%num2))

Explanation

The next two lines prompts the user for two numbers

num1 = int(input("Numerator: "))

num2 = int(input("Denominator: "))

The following if statement checks if one or both of the inputs is not positive

if num1 < 1 or num2<1:

print("Input must be greater than 1")-> If yes, the print statement is executed

If otherwise, the quotient and remainder is printed

else:

print("Quotient: "+str(num1//num2))

print("Remainder: "+str(num1%num2))

How do you fix this windows 7 screen

tensa zangetsu [6.8K]

Try restarting it. If you can’t restart because the screen is frozen maybe just turn it off and back on. If you already tried restarting and it still didn’t fix the problem, just give it some time. The computer will reset itself eventually which should fix the problem.

Given the function F (X, Y , Z)=Σm(0,1, 2 , 4 , 6)

Mnenie [13.5K]

Answer:

(1)Minterms complement = XYZ (2) Compliment of Minterms = Σm(0,1, 2 , 4 , 6) (3) (X+Y+Z) (4) Minimized SOP = Z + XY

Manterms = πM

Explanation:

Solution

Recall that:

Given the function F (X, Y , Z)=Σm(0,1, 2 , 4 , 6)

(1) Canonical Disjunctive Normal Form: In boolean algebra, the boolean function can be expressed as Canonical Disjunctive form known as minterms

In Minterm we assign 'I' to each uncomplimented variable and '0' to each complemented/complementary variable

For the given question stated we ave the following:

Minterms = XYZ, XYZ, XYZ, XYZ, XYZ.

(2) Canonical Conjunctive Normal Form: In boolean algebra, the boolean function can be expressed as Canonical Disjunctive form known as maxterms.

In Maxterms we assign '0' to each uncomplimented variable and '1' to each complemented/complementary variable

Compliment of Minterms = Σm(0,1, 2 , 4 , 6)

Maxterms = πM

Note: Kindly find an attached copy of the complete solution to this question below.
