Answer:

Relative greedy algorithm is not optimal

Explanation:

Proving that Relative’s greedy algorithm is not optimal.

This can be further proved by the following example.

Let us assumethe friends to be invited be Ali, Bill, David, Dennis, Grace, Eemi, and Sam.

The enemy list of each friend is shown below:

• Ali: Bill. David, Dennis

• Bill: Ali, Grace, Eemi, Sam

• David: Ali, Grace, Eemi, Sam

• Dennis: Ali, Grace, Eemi, Sam

• Grace: Bill. David, Dennis. Eemi . Sam

• Eemi: Bill, David, Dennis, Grace, Sam

• Sam: Bill, David, Dennis, Eemi, Grace

From the enemy list, the one with fewer enemies is Ali.

If we invite Ali, then Bill, David, and Dennis cannot be invited.

Next person that can be invited is one from Grace, Eemi, and Sam

If we choose any one of them we cannot add any other person.

For example, if we choose Grace, all other members are enemies of Ali and Grace. So only Ali

and Grace can only be invited.

So we get a list of two members using relative’s greedy algorithm.

This is not the optimal solution.

The optimal solution is a list of 3 members

• Bill, David, and Dennis can be invited to the party.

Hence, it is proved that relative’s greedy algorithm is not optimal, where the maximum number of friends is not invited to the party.

Write a program that uses nested loops to collect data and calculate the average rainfall over a period of years. The program sh

babunello [35]

Answer:

In Python:

year = int(input("Years: "))

while year<1:

year = int(input("Invalid. Enter 1 or greater: "))

total = 0

for i in range(1,year+1):

for j in range(1,13):

month = int(input("Year "+str(i)+", Month "+str(j)+": "))

while month<0:

month = int(input("Invalid. Enter 0 or greater: "))

total+=month

ave = total/(12*year)

print("Months: "+str(12 * year))

print("Total: "+str(total))

print("Average: "+str(ave))

Explanation:

This gets the number of years

year = int(input("Years: "))

This loop validates the number of years

<em>while year<1:</em>

<em> year = int(input("Invalid. Enter 1 or greater: "))</em>

<em />

This initializes total to 0

total = 0

This iterates through the years

for i in range(1,year+1):

This iterates through the month of each year

for j in range(1,13):

This gets the rainfall for each month

month = int(input("Year "+str(i)+", Month "+str(j)+": "))

This loop validates the amount of rainfall

<em> while month<0:</em>

<em> month = int(input("Invalid. Enter 0 or greater: "))</em>

This calculates the total rainfall

total+=month

This calculates the average rainfall

ave = total/(12*year)

This prints the number of month

print("Months: "+str(12 * year))

This prints the calculated total amount of rainfall

print("Total: "+str(total))

This prints the calculated average amount of rainfall

print("Average: "+str(ave))

Flauer [41]

The subsection which Frank is preparing for the SRS document that specifies data formats, data integrity, and storage capabilities is Logical Database Requirements.

<h3>What is SRS document?</h3>

SRS document of the software requirement specification document is the document which describes the function of a software and its procedure to perform a particular function.

Different types of requirement-

A. External Interface Requirements- This includes the interface of used, such as layout of screen, button etc.
B. Design Constraints- This includes the subcomponent of the system, such as performance requirement.
C. Inverse Requirements- It defines that what a system can not do.
D. Logical Database Requirements- Data of the user are saved in this such as profile, massage,data formats, data integrity, and storage capabilities etc.
E. Non-Functional Requirements-This includes attributes of system, performance, security etc.

Frank is preparing a subsection of the SRS document that specifies data formats, data integrity, and storage capabilities.

Thus, the subsection which Frank is preparing for the SRS document that specifies data formats, data integrity, and storage capabilities is Logical Database Requirements.
