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
def faster_pascal(row, col):
if (row == 0 or col == 0) or (row < col):
return 0
arr = [[0 for i in range(row+1)] for j in range(col+1)]
arr[0][0] = 1
for i in range(1, row+1):
for j in range(1, col+1):
if i == j or j == 0:
arr[i][j] = 1
else:
arr[i][j] = arr[i-1][j] + arr[i-1][j-1]
return arr[row][col]
MTBF is a measurement of
A) the speed at which a storage device can read and write data
B) the number of digits used to store a computer file
C) the average length of a time a storage device can reliably hold data without it beginning to degrade
D) the average length of time between failures on a device
MTBF is a measurement of the average length of time between failures on a device. Thus, the correct option for this question is D.
What is MTBF in computers?MTBF stands for Mean time between failures. It is often utilized in order to measure the overall failure rates, for both repairable and replaceable/non-repairable products.
It governs the simplest equation for mean time between failure. It is as follows:
MTBF = total operational uptime between failures/number of failures.It is the predicted elapsed time between inherent failures of a mechanical or electronic system during the normal functioning of the computer system in order to detect an error.
Therefore, MTBF is a measurement of the average length of time between failures on a device. Thus, the correct option for this question is D.

use router,switches and Hubs to design a simple network for maendeleo institute of Technology having 240 employees.The institute have five department: computer science has 100 employees ,information technology 60 employees ,Account 40 employees ,Human resource has 20 employees and marketing has 20 employees . Require: .network topology showing five network that corresponding to five department .use class C IP addresses (example 192.168.10.0/24) to show subnet ID and broadcast ID of each department , the IP address must not overlap .consider scalability .Give reason for your choice /decision
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.

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.

You are given a design board with four input pins a 4-bit INDATA,
1-bit Load,Enable, and Clock; and one output, a 4-bit OUTDATA.
Build a sequential circuit that contains a register (Don’t forget to
trigger that register by the FALLING edge of the clock, Logisim’s default
is the opposite!).
The register is updated every clock cycle in which Enable is up. If
Load is down, the register is incremented, otherwise it is loaded with the
data asserted on the INDATA pin.
The register data output should be connected with the output pin
OUTDATA.
The steps to Build a sequential circuit that contains a register is given below
The first step is to connect the 4-bit INDATA input to the data input of a 4-bit register.Next, we need to connect the Load and Enable inputs to a multiplexer. The multiplexer will be used to select between the INDATA input and the output of the register.The multiplexer output should be connected to the input of the register.We also need to create an AND gate that will be used to trigger the register on the falling edge of the clock. The AND gate should have the Clock input as well as the Enable input as its inputs.The output of the AND gate should be connected to the clock input of the register.The output of the register should be connected to the OUTDATA output.Create a NOT gate and connect the Load input to it, and connect the output of the NOT gate to one of the multiplexer input.Connect the output of the register to the second input of the multiplexer.What is the design board about?To build a sequential circuit that contains a register, we can use a combination of logic gates, flip-flops, and multiplexers.
In the above way, the register will be updated every clock cycle in which the Enable input is high. If the Load input is low, the multiplexer will select the output of the register and it will be incremented.
Otherwise, the multiplexer will select the INDATA input and the register will be loaded with the data asserted on the INDATA pin. The output of the register will be connected to the OUTDATA output, providing the register data.

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.

Next, you begin to clean your data. When you check out the column headings in your data frame you notice that the first column is named Company...Maker.if.known. (Note: The period after known is part of the variable name.) For the sake of clarity and consistency, you decide to rename this column Company (without a period at the end).
Assume the first part of your code chunk is:
flavors_df %>%
What code chunk do you add to change the column name?
Answer:
You can use the rename function to change the column name. Here is an example code chunk:
flavors_df %>%
rename(Company = Company...Maker.if.known.)
This will rename the Company...Maker.if.known. column to Company. Note that the old column name is surrounded by backticks () because it contains a period, which is a special character in R. The new column name, Company`, does not need to be surrounded by backticks because it does not contain any special characters.
