Expert Solution & Answer
Chapter 4, Problem 2ARQ
Explanation of Solution
New hardware affects the competitive strategies:
Generally, organizations get quite interested to use new hardware for their revenue generation based on potential opportunities or threats.
Internet of Things (IoT):
Internet of Things is a design where objects are linked with internet for interaction purposes. That is, interact with “devices”, “services”, or “applications”.
- Each and every day objects are embedded with hardware that used for “sensing”, “processing”, and “transmitting” data.
- Then objects are linked with internet to share the data with any other application, device, or service.
Smart device:
Smart device is a device which is added with extra features such as more processing power, more memory, Wi-Fi connectivity, net access, and so on.
Reason to use the smart devices:
- Nowadays, smart devices are essential. Because it is added with extra features such as more processing power, more memory, Wi-Fi connectivity, net access, and so on.
- People have started using smart phone much more than before.
- It helps to change the way of business operations.
- Business need to enhance the existing revenue with the help of smart devices.
Examples of how businesses could profit from smart device:
- One example is business from General Electric’s (GE) industrial internet.
- GE industrial internet is the broad plan which mainly focused to create the smart devices, investigating the data from these devices, and making changes to increase efficiencies, minimize the waste, and to enhance the decision making.
- The industry experiences huge profit by using smart devices in hospitals, railroads, power grids, and so on.
- Another example is business from Microsoft.
- Microsoft industry also made tremendous profits with the help of smart devices.
- The engineers from Microsoft were capable to minimize the energy cost and increase the profits.
Self-driving cars:
Self-driving cars is also known as driverless car.
- It uses the types of sensor to navigate the car without human intervention like traditional car...

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.

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()
else: e.release()
