Answer:
public class Main
{
public static void main(String[] args) {
int[] numbers = new int[40];
for (int i=0; i<40; i++){
numbers[i] = i * 3;
}
for (int i=0; i<40; i++){
System.out.println(numbers[i]);
}
}
}
Explanation:
*The code is in Java.
Initialize an integer array with size 40
Create a for loop that iterates 40 times. Inside the loop, set the number at index i as i*3
i = 0, numbers[0] = 0 * 3 = 0
i = 1, numbers[1] = 1 * 3 = 3
i = 2, numbers[2] = 2 * 3 = 6
.
.
i = 39, numbers[39] = 39 * 3 = 117
Create another for loop that iterates 40 times and prints the values in the numbers array

Compute the weakest precondition for each of the following assignment statements and postconditions:
a = 2 * (b - 1) - 1 {a > 0}
b = (c + 10) / 3 {b > 6}
a = a + 2 * b - 1 {a > 1}
x = 2 * y + x - 1 {x > 11}
Answer:
a) b > 3/2
b) c > 8
c) b > 1 - a/2
d) y > 6 - x/2
Explanation:
a)
a = 2 × (b - 1) - 1 {a > 0}
2 × (b - 1) - 1 > 0
2b - 2 - 1 > 0
2b - 3 > 0
2b > 3
b > 3/2
b)
b = (c + 10) / 3 {b > 6}
(c + 10) / 3 > 6
multiply both side by 3
((c + 10) / 3) × 3 > 6 × 3
c + 10 > 18
c > 18 - 10
c > 8
c)
a = a + 2 × b - 1 {a > 1}
a + 2 × b - 1 > 1
a + 2b - 1 > 1
a + 2b > 1 + 1
2b > 2 - a
divide both sides by 2
2b/2 > 2/2 - a/2
b > 1 - a/2
d)
x = 2 × y + x - 1 {x > 11}
2 × y + x - 1 > 11
2y + x - 1 > 11
2y + x > 11 + 1
2y + x > 12
2y > 12 - x
divide both sides by 2
2y/2 > 12/2 - x/2
y > 6 - x/2
One lap around a standard high-school running track is exactly 0.25 miles. Write the function miles_to_laps() that takes a number of miles as an argument and returns the number of laps. Complete the program to output the number of laps. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print('{:.2f}'.format(your_value))
Ex: If the input is: 2.2 the output is: 8.80 Your program must define and call the following function: def miles_to_laps(user_miles)
Answer:
def miles_to_laps(user_miles):
laps = user_miles / 0.25
return laps
miles = float(input("Enter number of miles: "))
print('{:.2f}'.format(miles_to_laps(miles)))
Explanation:
Create a function named miles_to_laps that takes one parameter, user_miles
Inside the function, calculate the number of laps, divide the user_miles by 0.25 (Since it is stated that one lap is 0.25 miles). Return the laps
Ask the user to enter the number of miles
Call the function with that input and print the result in required format

________ group is used to select font styles.
Answer:
The font group............. ...4. Word Separator:Write a program that accepts as input a sentence in which all of thewords are run together but the first character of each word is uppercase. Convert the sentence to a string in which the words are separated by spaces and only the first word starts with an uppercase letter. For example the string “StopAndSmellTheRoses.” would be converted to “Stop and smell the roses.”
*python coding
sent = input("")
count = 0
new_sent = ""
for i in sent:
if count == 0:
new_sent += i
count += 1
else:
if i.isupper():
new_sent += " "+i.lower()
else:
new_sent += i
print(new_sent)
The above code works if the user enters the sentence.
def func(sentence):
count = 0
new_sent = ""
for i in sentence:
if count == 0:
new_sent += i
count += 1
else:
if i.isupper():
new_sent += " " + i.lower()
else:
new_sent += i
return new_sent
print(func("StopAndSmellTheRoses."))
The above code works if the sentence is entered via a function.

Please write in python:
Week 1 (Print menu and take a selection)
At program start, you will print a menu with the contents of your vending machine.
Customize your own vending machine with items of your interest
Your vending machine should have at least 5 items
Accept items to be purchased, or until a sentinel value is entered.
Print the selected item after each selection.
Week 2 (Take many selections, calculate total, and accept payment)
Extend your code to allow users to repeatedly select items for purchase and keep a running subtotal
Your menu should contain a sentinel value for the user to select checkout as an option to finish shopping.
Check that the selection entered is an option of the menu. If not, then print an error message and start over requesting a new selection or to quit.
Calculate amount due with subtotal + sales tax (for your state).
Accept payment in whole dollars
Following the deposit (payment), calculate change due (difference between payment and amount due)
Week 3 (Dispense change)
Extend your code to determine the dollars and coins to be dispensed from the change due or as a refund. This calculation will depend on the payment accepted. For example, if the user selected items totaling $10.35 and they only deposit $7.00, they have provided insufficient payment.
Check that the payment received is greater than or equal to the amount due. If the payment is less than the amount due, then print an error message and prompt the user to enter sufficient funds. If the payment is equal to the amount due, then print a message saying “No change due.”
Print the number of dollars and coins to be dispensed and their denominations.
Week 4 (Incorporating functions)
Extend your code to include the following functions,
print_menu(): non-value returning function to print out the menu at the start of the program and after each item for purchase is chosen. This menu should contain a sentinel for the user to checkout when the user is finished selecting items.
calculate_total(new_item): a value returning function to add up the cost of the item selected.
make_change(change_due): (previous lab assignment): Calculate the users change (“Here is your change: “) in dollars and coins and print a closing message (“Have a great day”).
amount_due(total_price): a value returning function that prints a subtotal and final total that includes sales tax (for your state) added to the total. This function will also require the user to input a whole dollar amount for payment and return the amount of change due and should prompt the user to retry if too little cash is paid.Write a program that reads a list of integers into a list as long as the integers are greater than zero, then output the smallest and largest integers in the list.
