Program Plan Intro
Percentage Calculation
Program Plan:
ADT interface filename: “Percent.h”
- Include required header files.
- Define a class “Percent”.
- Declare function for overload operator “==” and “<”.
- Declare default constructor for “Percent” class.
- Declare a constructor for “Percent” class with one integer parameter.
- Declare function for input overload operator and output overload operator.
- Declare function for binary overload operators “+”, “-” and “*”.
- Declare a member variable “value”.
ADT implementation filename: “Percent.cpp”
- Include required header files.
- Define default constructor for “Percent” class.
- Here assign the value of “value” to “0”.
- Define constructor for “Percent” class with one integer parameter “percentValue”.
- In this constructor, assign “value” to “percentValue”.
- Define a function for overload operator “<”.
- This function is used to check whether the first percent is less than second percent or not.
- Define a function for overload operator “==”.
- This function is used to check whether the two percent’s are equal or not.
- Define a function for input operator “>>”.
- Define a function for input operator “<<”.
- Define a function for binary overload operator “+” to compute the sum of two percentages.
- In this function, create an object “sum”.
- Then compute the addition of two percent’s.
- Finally returns the result of addition.
- Define a function for binary overload operator “-” to compute the subtraction of two percentages.
- In this function, create an object “s”.
- Then compute the subtraction of two percent’s.
- Finally returns the result of subtraction.
- Define a function for binary overload operator “*” to compute the multiplication of one percent and an integer value.
- In this function, create an object “m”.
- Then compute the multiplication of one percent and an integer value.
- Finally returns the result of multiplication.
Application filename: “main.cpp”
- Include required header files.
- Define main function.
- Create two objects “percent1” and “percent2” from “Percent” class.
- Create an object “percent3” with one integer parameter “10”.
- Declare an integer variable “intValue”.
- Read the percentage 1 and percentage 2 from user.
- Check the two percentages using “==” operator.
- Check the two percentages using “<” operator.
- Create an object “sumPercent” from “Percent” class.
- Then compute and display sum of two percentages.
- Create an object “subPercent” from “Percent” class.
- Then compute and display difference of two percentages.
- Display percentage 3 from assigned value.
- Read an integer from user to multiply with a percentage 3.
- Finally compute and display the multiplication of “percent3” and a user entered integer value.

I need help in construct a matlab code to find the voltage, the currents, and the watts based on that circuit.
Objective
Implement Bottom-Up Iterative MergeSort and analyze its efficiency compared to
recursive MergeSort. Unlike the recursive approach, which involves multiple function
calls and stack overhead, the bottom-up version sorts iteratively by merging small
subarrays first, reducing recursion depth and improving performance.
Task
1. Implement Bottom-Up Iterative MergeSort
о Start with single-element subarrays and iteratively merge them into larger
sorted sections.
Use a loop-based merging process instead of recursion.
○ Implement an efficient in-place merging strategy if possible.
2. Performance Analysis
Compare execution time with recursive MergeSort on random, nearly
sorted, and reversed datasets.
○ Measure and plot time complexity vs. input size.

it performs better.

Given a shared data set, we allow multiple readers to read at the same time, and only one single writer can access the shared data at the same time. In the lecture slides, a solution is given. However, the problem is that the write cannot write forever, if there are always at least one reader.
How to ensure that the writer can eventually write? Propose your solution by using semaphores and implemented in Python
from threading import Thread, Semaphore
from time import sleep
from sys import stdout
class Reader(Thread):
def__init__(self, name):
self.n=name; Thread.__init__(self)
defrun(self):
globalnr, nw, dr, dw
whileTrue:
# ⟨await nw == 0 then nr += 1⟩
e.acquire()
ifnw>0:
#if nw > 0 or dw > 0 :
dr+=1; e.release(); r.acquire()
nr+=1
ifdr>0: dr-=1; r.release()
else: e.release()
# read data
stdout.write(self.n+' reading\n')
sleep(1)
# ⟨nr -= 1⟩
e.acquire()
nr-=1
ifnr==0anddw>0:
dw-=1 ; w.release()
