The advantage of using a belt drive over chain drive. vice versa

1 answer:

8 0

A belt drive requires less maintenance, lasts longer and is cleaner. It also delivers a smoother ride, which is why this type of drive system is most commonly used on cruiser motorcycles.

A chain drive delivers power more economically than a belt drive, and it sends more of the power that the engine produces to the wheel. While they require more maintenance, the improved performance means they are the more common type of drive method.

Write a Python program to balance a checkbook. The main function needs to get the initial balance, the amounts of deposits, and

Irina18 [472]

Answer:

def deposit(deposit_amount, balance):

balance += deposit_amount

return balance;

def process_check(check_amount, balance):

balance -= check_amount

return balance;

balance = float(input("Enter the initial balance: "))

transaction = input("Choose transaction method - D to deposit, C to process check, Q to quit: ")

while transaction != 'Q':

if transaction == 'D':

deposit_amount = float(input("Enter amount to be deposited: "))

balance = deposit(deposit_amount, balance)

print("Current balance is: " + str(balance))

elif transaction == 'C':

check_amount = float(input("Enter amount to process check: "))

if balance >= check_amount:

balance = process_check(check_amount, balance)

print("Current balance is: " + str(balance))

else:

print("Not enough money!")

else:

print("Invalid input!")

transaction = input("Choose transaction method - D to deposit, C to process the check, Q to quit: ")

print("Your final balance is: " + str(balance))

Explanation:

- Create functions to handle deposits and checks

- Ask the user for the initial balance and transaction to be made

- Initialize a while loop iterates until the user enter Q

- Ask the deposit amount or check amount depending on the transaction chosen

- Calculate and print the current balance for each transaction

- Print the final balance

Greedy Algorithm Design

Alik [6]

Answer:

The algorithm is as follows:

1. Start

2. Get the number of items (n)

3. Get the current price of the n items (a1, a2..... an)

4. Get the possible hiked price of the n items (b1, b2..... bn)

5. Calculate the difference between the current and hiked prices for each item i.e. $d_i = b_i - a_i$

6. Sort the differences in descending order (i.e. from the greatest to the least)

7. Buy items in this order of difference

8. Stop

Explanation:

The algorithm is self-explanatory; however, what it does is that:

It takes a list of the current price of items (say list a)

E.g: $a = [100, 150, 160]$

Then take a list of the hiked price of the items (say list b)

E.g: $b = [110, 180, 165]$

Next, it calculates the difference (d) between corresponding prices $d_i = b_i - a_i$

$d = [(110 - 100),(180-150),(165-160)]$

$d = [10,30,5]$

Sort the difference from greatest to lowest (as the difference is sorted, lists a and b are also sorted)

$d = [30,10,5]$

$a = [150, 100, 160]$

$b = [180, 110, 165]$

If there is no hike up to item k, the couple would have saved (i = 1 to d[k-1])

Assume k = 3

The couple would have saved for 2 item

$Savings = d[1] + d[2]$

$Savings = 30 +10$

$Savings = 40$

The saved amount will then be added to the kth item in list a i.e. a[k](in this case k = 3) in order to buy b[k]

Using the assumed value of k

$a[k] = a[3]$

$a[3] = 160$

$b[3] = 165$

Add the saved amount (40) to a[3]

$New\ Amount = 40 + 160$

$New\ Amount = 200$

This new amount can then be used to buy b[3] i.e. 165, then they save the change for subsequent items
