I have been working on this python program for a hour now, and I am trying to figure out what I an doing wrong in the loop. I have attached the code and screenshot of my work. I need help to figure out how to loop the rest of the years for a calculation. The calculation has looped the same result for all years.
This is the assignment:
In 2017, the tuition for a full time student is $6,450 per semester. The tuition will be going up for the next 7 years at a rate of 3.5% per year. Write your python program using a loop that displays the projected semester tuition for the next 7 years. You should display the actual year (2018, 2019, through 2024) and the tuition amount per semester for that year.
Here is my code:
# declare global constant variables
startingTuition = 6450.00;
starting_tuitionYear = 2018;
ending_tuitionYear = 2025;
increment = 1;
rate = .035;
tuition = 0;
tuitionRate = 0;
#loop for the next 7 years
for year in range(starting_tuitionYear, ending_tuitionYear, increment):
# calculate rate per year
tuitionRate = (rate)*startingTuition;
# add rate per year to the tuition fee
tuition = startingTuition + tuitionRate;
print('Tuition for the year of ' + str(year)+ ' is ' + str(tuition));
Answers
Answer:
The correct loop is as follows:
for year in range(starting_tuitionYear, ending_tuitionYear, increment):
tuition = startingTuition + rate * startingTuition
startingTuition = tuition
print('Tuition for the year of ' + str(year)+ ' is ' + str(tuition));
Explanation:
Required
The correction to the attached program
Some variables are not needed; so, I've removed the redundant variables.
The main error in the program is in the loop;
After the tuition for each year has been calculated, the startTuition of the next year must be set to the current tuition

Python question
The following code achieves the task of adding commas and apostrophes, therefore splitting names in the list. However, in the case where both first and last names are given how would I "tell"/write a code that understands the last name and doesn't split them both. For example 'Jack Hansen' as a whole, rather than 'Jack' 'Hansen'.
names = "Jack Tomas Ponce Ana Mike Jenny"
newList = list(map(str, names.split()))
print(newList) #now the new list has comma, and apostrophe
Answers
Answer:
You can use regular expressions to match patterns in the names and split them accordingly. One way to do this is to use the re.split() function, which allows you to split a string based on a regular expression.
For example, you can use the regular expression (?<=[A-Z])\s(?=[A-Z]) to match a space between two capital letters, indicating a first and last name. Then use the re.split() function to split the names based on this regular expression.
Here is an example of how you can use this approach to split the names in your list:
(Picture attached)
This will give you the output ['Jack', 'Tomas', 'Ponce', 'Ana', 'Mike', 'Jenny', 'Jack Hansen']. As you can see, the name "Jack Hansen" is not split, as it matches the pattern of first and last name.
It's worth noting that this approach assumes that all first and last names will have the first letter capitalized and the last names capitalized too. If this is not the case in your data, you may need to adjust the regular expression accordingly.

In this lab, you use what you have learned about searching an array to find an exact match to complete a partially prewritten C program. The program uses an array that contains valid names for 10 cities in Michigan. You ask the user to enter a city name; your program then searches the array for that city name. If it is not found, the program should print a message that informs the user the city name is not found in the list of valid cities in Michigan. The file provided for this lab includes the input statements and the necessary variable declarations. You need to use a loop to examine all the items in the array and test for a match. You also need to set a flag if there is a match and then test the flag variable to determine if you should print the the Not a city in Michigan. message. Comments in the code tell you where to write your statements. You can use the previous Mail Order program as a guide. Instructions Ensure the provided code file named MichiganCities.cpp is open. Study the prewritten code to make sure you understand it. Write a loop statement that examines the names of cities stored in the array. Write code that tests for a match.

The pre-written code; though missing in this question, can be found online.
The explanation of the added lines of code is as follows:
This iterates through the array

This checks if the city exists in the array
if(inCity == citiesInMichigan[i]){
If yes, foundIt is updated to true
foundIt = true;
And the loop is exited

The are two schools of ____________ are Symmetry and Asymmetry.
Answers
The two schools of design that encompass symmetry and asymmetry are known as symmetrical design and asymmetrical design.
Symmetrical design is characterized by the balanced distribution of visual elements on either side of a central axis. It follows a mirror-like reflection, where the elements on one side are replicated on the other side, creating a sense of equilibrium and harmony.
Symmetrical designs often evoke a sense of formality, stability, and order.
On the other hand, asymmetrical design embraces a more dynamic and informal approach. It involves the intentional placement of visual elements in an unbalanced manner, without strict adherence to a central axis.
Asymmetrical designs strive for a sense of visual interest and tension through the careful juxtaposition of elements with varying sizes, shapes, colors, and textures.
They create a more energetic and vibrant visual experience.
Both symmetrical and asymmetrical design approaches have their merits and are employed in various contexts. Symmetry is often used in formal settings, such as architecture, classical art, and traditional graphic design, to convey a sense of elegance and tradition.
Asymmetry, on the other hand, is commonly found in contemporary design, modern art, and advertising, where it adds a sense of dynamism and creativity.
In conclusion, the schools of symmetry and asymmetry represent distinct design approaches, with symmetrical design emphasizing balance and order, while asymmetrical design embraces a more dynamic and unbalanced aesthetic.

The 0-1 knapsack problem is the following. A thief robbing a store finds n items. The ith item is worth vi dollars and weighs wi pounds, where vi and wi are integers. The thief wants to take as valuable a load as possible, but he can carry at most W pounds in his knapsack, for some integer W . Which items should he take?
Answers
Step by step Explanation:
Based on what we could deduce from the above statement, the items he should take are:
must either take one single item or must leave the other behind,and only a whole amount of an item must be taken,in which an item cannot be taken more than once into his knapsack.Hence, the thief needs to carefully determine items with an optimal value which still falls within his specified weight (W).
In this exercise, we examine how pipelining affects the clock cycle time of the processor. Problems in this exercise assume that individual stages of the datapath have the following latencies:
IF ID EX MEM WB
250ps 350ps 150ps 300ps 200ps
Also, assume that instructions executed by the processor are broken down as follows:
alu beq sw sw
45% 20% 20% 15%
1. What is the clock cycle time in a pipelined and non-pipelined processor?
2. What is the total latency of an LW instruction in a pipelined and non-pipelined processor?
3. If we can split one stage of the pipelined datapath into two new stages, each with half the latency of the original stage, which stage would you split and what is the new clock cycle time of the processor?
4. Assuming there was are no stalls or hazards, what is the utilization of the data memory?
5. Assuming there are no stalls or hazards, what is the utilization of the write-register port of the "Registers" unit?
6. Instead of a single-cycle organization, we can use a multi-cycle organization where each instruction takes multiple cycles but one instruction finishes before another is fetched. In this organization, an instruction only goes through stages it actually needs (e.g., ST only takes 4 cycles because it does not need the WB stage). Compare clock cycle times and execution times with single-cycle, multi-cycle, and pipelined organization
Answers
The clock cycle time in a pipelined and non-pipelined processor will be 350ps and 1250ps respectively.
1. The clock cycle time in a pipelined processor will be the slowest instruction decode which is 350ps. The clock cycle time in a non-pipelined processor will be:
= 250 + 350 + 150 + 300 + 200
= 1250ps
2. The total latency of an LW instruction in a pipelined processor will be:
= 5 × 350 = 1750ps.
The total latency of an LW instruction in a non-pipelined processor will be:
= 250 + 350 + 150 + 300 + 200
= 1250ps
3. Based on the information asked, the stage to be split will be the cycle time. Now, the new cycle time will be based on the longest stage which will be 300ps.
4. It should be noted that the store and load instruction is used for the utilization of memory. The load instruction is 20% of the time while the store instruction is 15% of the time. Therefore, the utilization of data memory will be:
= 20% + 15% = 35%
5. The utilization of the write-register port of the "Registers" unit will be:
= 20% + 45% = 65%
6. The multi cycle execution time will be:
= (5 × 20%) + [4 × (45% + 20% + 15%)]
= (5 × 0.2) + (4 × 0.8)
= 1 + 3.2
= 4.2
The single cycle execution time will be:
= Cycle time non-pipeline / Cycle time pipeline
= 1250/350
= 3.5

Answers
In the given syntax, the column "I-city" in the "where" clause is the best candidate for an index.
What is the explanation for the above response?The selectivity of an index refers to the percentage of rows in the table that match a specific value in the indexed column. Since the query filters by the value of the "I-city" column, creating an index on this column would improve the query's performance by allowing the database to quickly locate and retrieve the matching rows.
In this case, if a significant portion of the Instructors table has a "Houston" value in the "I-city" column, creating an index on this column would result in a high selectivity, making it a good candidate for indexing.

A backup operator wants to perform a backup to enhance the RTO and RPO in a highly time- and storage-efficient way that has no impact on production systems. Which of the following backup types should the operator use?
A. Tape
B. Full
C. Image
D. Snapshot
Answers
In this scenario, the backup operator should consider using the option D-"Snapshot" backup type.
A snapshot backup captures the state and data of a system or storage device at a specific point in time, without interrupting or impacting the production systems.
Snapshots are highly time- and storage-efficient because they only store the changes made since the last snapshot, rather than creating a complete copy of all data.
This significantly reduces the amount of storage space required and minimizes the backup window.
Moreover, snapshots provide an enhanced Recovery Time Objective (RTO) and Recovery Point Objective (RPO) as they can be quickly restored to the exact point in time when the snapshot was taken.
This allows for efficient recovery in case of data loss or system failure, ensuring minimal downtime and data loss.
Therefore, to achieve a highly time- and storage-efficient backup solution with no impact on production systems, the backup operator should utilize the "Snapshot" backup type.
