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
return table[row][col]
print(faster_pascal(3, 2))
print(faster_pascal(4, 3))
print(faster_pascal(100, 45))
print(faster_pascal(500, 3))
print(faster_pascal(1, 1))

Write a procedure ConvertToBinary that takes an input as a number from 0 to 16 (including 0 but not 16) and converts it to a binary number. The binary number should be returned as a list.
Sure, here's an example of a Python function that converts a decimal number to binary and returns the result as a list:
def ConvertToBinary(decimal):
binary = []
while decimal > 0:
remainder = decimal % 2
binary.append(remainder)
decimal = decimal // 2
return binary[::-1]
The function takes in an input decimal which is a number between 0 and 16 (not including 16) and uses a while loop to repeatedly divide the decimal number by 2 and take the remainder. The remainders are then appended to a list binary. Since the remainders are appended to the list in reverse order, the result is reversed by slicing the list [-1::-1] to give the proper order.
You can also add a check to make sure that the input is within the required range:
def ConvertToBinary(decimal):
if decimal < 0 or decimal >= 16:
return None
binary = []
while decimal > 0:
remainder = decimal % 2
binary.append(remainder)
decimal = decimal // 2
return binary[::-1]
this way you can make sure that the input provided is within the allowed range.

Use routers, Switches and Hubs to design a simple network for Maendeleo Institute of Technology having 240 employees. 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.

Whenever you see a lowercase i, replace it with an exclamation point in the list
Return the stringified version of the list when your for loop is finished"

In this task, we will be finding a possible solution to number puzzles like 'SAVE' + 'MORE' = 'MONEY'. Each alphabet represents a digit. You are required to implement a function addition_puzzle that returns a dictionary containing alphabet-digit mappings that satisfy the equation. Note that if there are multiple solutions, you can return any valid solution. If there is no solution, then your function should return False.
>>> addition_puzzle('ANT', 'MAN', 'COOL')
{'A': 8, 'C': 1, 'L': 9, 'M': 6, 'N': 7, 'O': 5, 'T': 2}
>>> addition_puzzle('AB', 'CD', 'E')
False
Explanations:
ANT + MAN = COOL: 872 + 687 = 1559
AB + CD = E: The sum of two 2-digit numbers must be at least a two-digit number.
Your solution needs to satisfy 2 conditions:
The leftmost letter cannot be zero in any word.
There must be a one-to-one mapping between letters and digits. In other words, if you choose the digit 6 for the letter M, then all of the M's in the puzzle must be 6 and no other letter can be a 6.
addition_puzzle takes in at least 3 arguments. The last argument is the sum of all the previous arguments.
Note: The test cases are small enough, don't worry too much about whether or not your code will run within the time limit.
def addition_puzzle(*args):
pass # your code here
Answer:
Here is one possible solution to this problem in Python:
from itertools import permutations
def addition_puzzle(*args):
# Get all permutations of the digits 0-9
digits = list(range(10))
all_permutations = list(permutations(digits))
# Iterate through each permutation
for perm in all_permutations:
# Create a dictionary mapping each alphabet to a digit
mapping = {alphabet: digit for alphabet, digit in zip(args[0], perm)}
if all(mapping[alphabet] != 0 for alphabet in args[0]):
# Check if the sum of the numbers is equal to the last argument
num1 = int(''.join(str(mapping[alphabet]) for alphabet in args[1]))
num2 = int(''.join(str(mapping[alphabet]) for alphabet in args[2]))
if num1 + num2 == int(''.join(str(mapping[alphabet]) for alphabet in args[3])):
return mapping
# If no solution is found, return False
return False
print(addition_puzzle('ANT', 'MAN', 'COOL'))
print(addition_puzzle('AB', 'CD', 'E'))
Explanation:
This solution first generates all possible permutations of the digits 0-9 using the permutations function from the itertools module. Then, it iterates through each permutation and creates a dictionary mapping each alphabet to a digit. It checks if the leftmost letter in any word is not zero and if the sum of the numbers is equal to the last argument. If both conditions are satisfied, it returns the mapping. If no solution is found after iterating through all permutations, it returns False.
The user is able to input grades and their weights, and calculates the overall final mark. The program should also output what you need to achieve on a specific assessment to achieve a desired overall mark. The program should be able to account for multiple courses as well.
I have done some pseudocode. So to double check, please provide pseudocode and python code.
I do plan to use homework, quizzes and tests for the grades portion and using the exam as part of the desired mark portion.
Answer:
Here is some pseudocode that outlines the steps for creating a program that calculates overall final marks and outputs the necessary grades for a desired overall mark:
DEFINE a function called "calculate_final_mark"
INPUT: grades (list), weights (list), desired_mark (float)
CREATE a variable called "overall_mark" and set it to 0
FOR each grade and weight in the grades and weights lists:
MULTIPLY the grade by the weight
ADD the result to the overall_mark
IF overall_mark equals the desired_mark:
OUTPUT "You have already achieved the desired mark."
ELSE:
CREATE a variable called "needed_mark" and set it equal to the desired_mark minus the overall_mark
OUTPUT "You need a" needed_mark "on your next assessment to achieve a" desired_mark "overall mark."
END the function
Here is the equivalent code in Python:
def calculate_final_mark(grades, weights, desired_mark):
overall_mark = 0
for grade, weight in zip(grades, weights):
overall_mark += grade * weight
if overall_mark == desired_mark:
print("You have already achieved the desired mark.")
else:
needed_mark = desired_mark - overall_mark
print(f"You need a {needed_mark} on your next assessment to achieve a {desired_mark} overall mark.")

Since you now have a good understanding of the new situation, write a new num_of_paths function to get the number of ways out. The function should take in a map of maze that Yee Sian sent to you and return the result as an integer. The map is a tuple of n tuples, each with m values. The values inside the tuple are either 0 or 1. So maze[i][j] will tell you what's in cell (i, j) and 0 stands for a bomb in that cell.
For example, this is the maze we saw in the previous question:
((1, 1, 1, 1, 1, 1, 1, 1, 0, 1),
(1, 0, 0, 1, 1, 1, 0, 0, 1, 1),

(0, 1, 0, 1, 0, 0, 1, 0, 1, 0),
(1, 0, 1, 1, 1, 1, 0, 1, 1, 1),
(0, 1, 1, 1, 1, 1, 1, 1, 1, 0),

2.2 If maze[0][j] has a bomb, set table[(0, k)] where k >= j to be 0. Since one cell is broken along the way, all following cells (in the first row) cannot be reached.
Fill in the first column. For i in range n:
3.1 If maze[i][0] is safe, set table[(i, 0)] to be 1 because there's one way to go there.
3.2 If maze[i][0] has a bomb, set table[(i, 0)] and all cells under it to be 0. The reason is same as for the first row.
Main dynamic programming procedure - fill in the rest of the table.
If maze[i][j] has a bomb, set table[(i, j)] = 0.
Otherwise, table[(i, j)] = table[(i - 1, j)] + table[(i, j - 1)]
Return table[(n - 1, m - 1)]

Answer:
1. Syntax: Syntax is the structure of a programming language which includes rules for constructing valid statements and expressions.
2. Data Types: Data types are used to define the type of data that is stored in a variable.
3. Variables: Variables are used to store data values.
4. Operators: Operators are used to perform operations on variables and values.
5. Control Structures: Control structures are used to control the flow of a program.
6. Functions: Functions are used to group related code into a reusable block.
7. Libraries: Libraries are collections of functions and data structures that can be used in a program.
8. Comments: Comments are used to document code and make it easier to understand.
