Suppose that you have a list of numbers, and you need to normalize the list, i.e., the sum of all numbers in the list is equal to 1.
Tam came out with an implementation:
def normalize(lst):
s = sum(lst)
return list(map(lambda v: v / s, lst))
This code works correctly for normalize([1, 2, 5, 4]) but fails for normalize([1, 2, -7, 4]). What causes the second test case to fail?
Find out the error message and keep the list as it is when the error occurs by simply return the list. So without modifying the normalize function, implement this strategy in the safe_normalize function. Complete safe_normalize. You may assume that the normalize function has already been defined for you.
def safe_normalize(lst):
# handle the error
return normalize(lst)
Test Cases:
safe_normalize([1, 2, 2, 3]) [0.125, 0.25, 0.25, 0.375]
safe_normalize([1, 2, -5, 2]) [1, 2, -5, 2]
Here is an implementation of the safe_normalize function that catches the error and returns the original list if an error occurs:
def safe_normalize(lst):
try:
return normalize(lst)
except ZeroDivisionError:
return lst
This function calls the normalize function, which takes a list as input and returns a normalized list. However, if an error occurs (in this case, a ZeroDivisionError), the function will catch the error and return the original list instead.
To test the safe_normalize function, you can use the following test cases:
print(safe_normalize([1, 2, 2, 3])) # Expected output: [0.125, 0.25, 0.25, 0.375]
print(safe_normalize([1, 2, -5, 2])) # Expected output: [1, 2, -5, 2]
The first test case should return the normalized list, while the second test case should return the original list, since the normalize function would fail with a ZeroDivisionError if passed a list with a negative sum.

You had learnt how to create the Pascal Triangle using recursion.
def pascal(row, col):
if col == 1 or col == row:
return 1
else:
return pascal(row - 1, col) + pascal(row - 1, col - 1)
But there is a limitation on the number of recursive calls. The reason is that the running time for recursive Pascal Triangle is exponential. If the input is huge, your computer won't be able to handle. But we know values in previous rows and columns can be cached and reused. Now with the knowledge of Dynamic Programming, write a function faster_pascal(row, col). The function should take in an integer row and an integer col, and return the value in (row, col).
Note: row and col starts from 1.
Test Cases:
faster_pascal(3, 2) 2
faster_pascal(4, 3) 3
faster_pascal(100, 45) 27651812046361280818524266832
faster_pascal(500, 3) 124251
faster_pascal(1, 1) 1
Answer:
def faster_pascal(row, col):
# Create a list of lists to store the values
table = [[0 for x in range(col + 1)] for x in range(row + 1)]
# Initialize the first row
table[1][1] = 1
# Populate the table
for i in range(2, row + 1):
for j in range(1, min(i, col) + 1):
# The first and last values in each row are 1
if j == 1 or j == i:
table[i][j] = 1
# Other values are the sum of values just above and left of the current cell
else:
table[i][j] = table[i-1][j-1] + table[i-1][j]
# Return the required result

Answer:
Explanation:
The biggest question now is how do we attract more women into the computer science field. Women need more encouragement, especially from teachers of both sexes and fellow students. Mentoring is a definite means to attract and keep women more interested in the field. Even just the support of other females present in a classroom setting can help boost the confidence in each other. Multiple studies have shown that the lack of women in computer science is very likely to start before college (Cohoon). They need this encouragement not only while taking college courses but also early on in their education. Females tend to be just as interested in science as men when they are young but their teachers and schools, who would have the most influence on them, aren’t doing their job in nurturing and identifying these women (Gurian). A possible solution to improving their confidence would be to have more mentors who can help attract and keep women interested in the field. The shortage of women in the computer science field has made it more difficult to have women in high positions. This makes it important for women who are in high positions to be mentors to all women interested. According to Joanne Cohoon a professor at the University of Virginia “CS departments generally retained women at comparable rates to men when the faculty included at least one woman; was mentored, and supervised female students; enjoyed teaching; and shared responsibility for success with their students”. It is also found that departments with no female faculty lost female students at high rates relative to men (Cohoon). Seeing other women in computer science can definitely raise confidence in women to continue or begin studying the subject. “In a new survey, 40 percent of women in the STEM fields… report that they were discouraged from their career choices, typically in college and often by their professors” (Downey). This data shows how we need more mentors willing to support women and that we are lacking teachers to help inspire young women into entering the field.
Since the beginning of computing most software and programs have been male-oriented. Video games were originally targeted at males with sport and violent themes with mostly male lead characters and limiting female roles like women who need to be rescued (Lynn). Early experiences with computers are important in shaping someone’s willingness to explore technology. “Playing with computer, console, and arcade games and educational ware can provide an introduction to computer literacy, creating familiarity and building confidence in skills” (Lynn, 145). Because computer science is so dominated by men, the software tends to be more male- friendly. To make software more appealing to girls, it should have low frustration levels, be challenging and be interactive (Lynn). By having more women in the field, women can create much more women-friendly software. Girls tend to prefer games where they can make things, rather than destroy them(Lynn). Recently more and more games have been produced that are more girl-friendly, like simulation games. The Sims is a video game where you create humans, animals and homes and has proved to be a big success with a female audience. A strategy to get more women to break outside the stereotype of women being less competitive than men would be to take games designed for boys and demand comparable female characters to empower them to be more competitive and assertive. Video games often become involved with computing as a byproduct of wanting to master gaming (Lynn).
Many boys tend to have more experience with computers at a younger age because of video games, when boys and girls are put together in a class to learn about computers the boys are already at a higher level, which is not encouraging to the women beginning at a lower level in the same class. Making more computer classes mandatory both in high school and at the college level will not only help women because of the increasing number of other female peers, but it can spark interest in women early on, helping teachers to identify students with aptitude.

The Institute has five departments: Computer Science has 100 employees, Information Technology 60 employees, Accounts 40 employees, Human Resource has 20 employees and Marketing has 20 employees.
Required:
• Network topology showing five network that corresponds to five departments.
• Use Class C IP addresses (example 192.168.10.0/24) to show the subnet ID and broadcast ID of each department, the IP address must not overlap
• Consider Scalability
• Give reasons for your choice/ decisions
Answer:
To design a simple network for Maendeleo Institute of Technology with 240 employees, we could use a combination of routers, switches, and hubs.
Our network would consist of five separate networks, one for each department at the institute. We would use class C IP addresses, with a subnet mask of /24, to create the following subnets:
Computer Science department: 192.168.10.0/24
Information Technology department: 192.168.11.0/24
Account department: 192.168.12.0/24
Human Resource department: 192.168.13.0/24
Marketing department: 192.168.14.0/24
Each department would be connected to the network via a switch, which would allow for communication within the department and with other departments as needed. A router would be used to connect the individual department networks to the wider internet, and would also serve as a firewall to protect the network from external threats.
We would also include a hub in the network to allow for communication between devices within a department, as well as to provide additional connectivity and scalability.
Overall, our network design would provide each department with its own separate network, with the ability to communicate with other departments as needed. It would also be scalable, allowing for the addition of new devices and departments as the institute grows. The use of class C IP addresses and a /24 subnet mask would ensure that IP addresses do not overlap, ensuring efficient and reliable communication within the network.

Create a program for the given problems using one-dimensional array. Program to identify if the input number is odd or even.
Answer:
Here's an example of a simple program in Python that uses a one-dimensional array to determine if a given number is odd or even:
def check_odd_even(arr):
for i in range(len(arr)):
if arr[i] % 2 == 0:
print(str(arr[i]) + " is even")
else:
print(str(arr[i]) + " is odd")
# Example usage
numbers = [1, 2, 3, 4, 5, 6, 7]
check_odd_even(numbers)
The program defines a function check_odd_even that takes an array of numbers as an input. It then iterates over the array, checking the remainder of each number when divided by 2. If the remainder is 0, the number is even, if not then it is odd. The program then prints whether each number is even or odd.
You can input any array you want, of any lenght, and the function will work the same way.
Keep in mind that you can also check the parity in another ways, like using bitwise operation.
