Answer:
When Scheme is a pure functional language, it cannot include the function DISPLAY. Since the pure functional languages will return the same value whenever the same expression is evaluated, and the DISPLAY would be the output and thus it cannot be part of the purely functional language. Thus in the pure functional language we can evaluate the expressions with the same arguments and it returns the same value since there is no state to change.
Explanation:
. In the select algorithm that finds the median we divide the input elements into groups of 5. Will the algorithm work in linear time if we divide it into groups of 7? How about 3? Explain your answer--- the asymptotic run time in either case.
Answer:
we have that it grows more quickly than linear.
Explanation:
It will still work if they are divided into groups of 77, because we will still know that the median of medians is less than at least 44 elements from half of the \lceil n / 7 \rceil⌈n/7⌉ groups, so, it is greater than roughly 4n / 144n/14 of the elements.
Similarly, it is less than roughly 4n / 144n/14 of the elements. So, we are never calling it recursively on more than 10n / 1410n/14 elements. T(n) \le T(n / 7) + T(10n / 14) + O(n)T(n)≤T(n/7)+T(10n/14)+O(n). So, we can show by substitution this is linear.
We guess T(n) < cnT(n)<cn for n < kn<k. Then, for m \ge km≥k,
\begin{aligned} T(m) & \le T(m / 7) + T(10m / 14) + O(m) \\ & \le cm(1 / 7 + 10 / 14) + O(m), \end{aligned}
T(m)
≤T(m/7)+T(10m/14)+O(m)
≤cm(1/7+10/14)+O(m),
therefore, as long as we have that the constant hidden in the big-Oh notation is less than c / 7c/7, we have the desired result.
Suppose now that we use groups of size 33 instead. So, For similar reasons, we have that the recurrence we are able to get is T(n) = T(\lceil n / 3 \rceil) + T(4n / 6) + O(n) \ge T(n / 3) + T(2n / 3) + O(n)T(n)=T(⌈n/3⌉)+T(4n/6)+O(n)≥T(n/3)+T(2n/3)+O(n) So, we will show it is \ge cn \lg n≥cnlgn.
\begin{aligned} T(m) & \ge c(m / 3)\lg (m / 3) + c(2m / 3) \lg (2m / 3) + O(m) \\ & \ge cm\lg m + O(m), \end{aligned}
T(m)
≥c(m/3)lg(m/3)+c(2m/3)lg(2m/3)+O(m)
≥cmlgm+O(m),
therefore, we have that it grows more quickly than linear.

7. System software is the set of software programs that helps run the computer and coordinates instructions between application software and hardware devices. It consists of the operating system (OS) and utility programs. How does the mindset of the designer affect the design of the operating system (e.g., Windows vs. Linux)
Answer:
Explanation:
The main goal when designing an operating system (OS) is to make sure that the system is as efficient and intuitive as possible. This is the mindset that designers have when creating the operating system. However, this also creates drastically different designs between designers, mainly because one design structure will feel much more natural and intuitive to one designer but not another. Since the designer's own personal taste/mindset drastically affects the design, most companies find their target audience and survey/test various designs. This is done in order to find what features and styles best fit the vast majority of the people.

Scenarios are quite common where an IT professional is tasked with modify a file on many computer systems or many files on a single computer or a combination of the two. For example, a large software may need the copyright notice comment to be changed on every source file in the project. Or, a configuration file may need to be modified on every server in a multi-server deployment. Doing this task manually is not a viable way to approach the problem. Instead, a better solution is to use a scriptable environment to perform search and replace functionality on the files in question. Python is an excellent tool for this kind of task.
Description
Samba is a unix/linux file sharing suite of programs designed to provide Windows interoperable file and print sharing services. Much of the configuration for the Samba daemon is provided by the text file smb.conf (renamed to smb.txt for this assignment). After an update was deployed to three dozen linux servers it was discovered that a couple of configured parameters were incorrect. Unfortunately, since there are unique aspects to each server, copying the contents of a single file to each server is not a viable solution. To fix the problem, the IT department must connect to each server, edit the smb.conf file, and restart the smbd daemon. To automate this task, each server will have a Python script copied to it. Then an SSH session will be initiated to each server from which the script will be executed. Your task is to write the Python script.
The invocation of the script must be as follows:
python modify.py fileSpec "from" "to"
where,
modify.py is the name of your script
fileSpec is the name of the file to be modified (smb.txt)
"from" is the text to be searched for (be sure to enclose any white space in quotes.
"to" is the text the searched text is to be replaced with.
Testing the script is your responsibility. However a good test case is:
python modify.py smb.txt "password sync = yes" "password sync = no"
Answer:
Explanation:/
The example Python script that can be used to automate the modification of the smb.conf file on multiple Linux servers is shown below
What is the code?python
import subprocess
import sys
def modify_smb_conf(file_spec, search_text, replace_text):
try:
# Open the file for reading
with open(file_spec, 'r') as file:
# Read the contents of the file
file_contents = file.read()
# Perform the search and replace operation
modified_contents = file_contents.replace(search_text, replace_text)
# Open the file for writing
with open(file_spec, 'w') as file:
# Write the modified contents back to the file
file.write(modified_contents)
# Print a success message
print(f"Modification successful: Replaced '{search_text}' with '{replace_text}' in {file_spec}")
except IOError as e:
# Print an error message if there was an issue with file operations
print(f"Error: {e}")
def main():
# Check if the correct number of command line arguments are provided
if len(sys.argv) != 4:
print("Usage: python modify.py fileSpec \"from\" \"to\"")
return
# Extract the command line arguments
file_spec = sys.argv[1]
search_text = sys.argv[2]
replace_text = sys.argv[3]
# Call the function to modify the smb.conf file
modify_smb_conf(file_spec, search_text, replace_text)
if __name__ == '__main__':

Write a program that reads in an integer, and breaks it into a sequence of individual digits. Display each digit on a separate line. For example, the input 16384 is displayed as 1 6 3 8 4 You may assume that the input has no more than five digits and is not negative.
Answer:
The program in Python is as follows:
num = int(input())
for i in str(num):
print(int(i))
Explanation:
This gets input for the number
num = int(input())
This converts the number to string and iterates through each element of the string
for i in str(num):
This prints individual digits
