He said Read a natural number n with a maximum of 16 digits. Either q the number of digits in the number born by removing a single digit number n is given by writing a sequence of q numbers. To be displayed in ascending order, the numbers in this sequence which not null are prime number b. input data input File numere16.in contains the first line number b. output Data the output file URnumere16.out will contain the first line separated by a space, that respects the ownership requirement. Restrictions and details 2 ≤ q ≤ 16 if we don't have any numbers that respects us permission requirement message does not exist. if you can help him read this

/*

This program will simulate a tunnel with a limit of how many cars may move through it,

and will also simulate the cars going north and south-bound through the tunnel. We will

use pthreads, pthread mutexes, and pthread condition variables to simulate this.

Python: Write a program for a small restaurant that sells pizzas. You may consider it as a prototype of a realistic online appli

katrin2010 [14]

Answer:

Name: tyler

Number of pizzas: 2

Small (10 inch, $7.95), Medium (12 inch, $9.95), and Large (14 inch, $11.95)

Pizza size: large

Available toppings: Ham, Mushrooms, Onions, Green Peppers, Black Olives, Tomatoes, Pineapple, Spinach

$0.75 each for Small Pizza, $0.95 each for Medium Pizza, and $1.15 each for Large Pizza

Number of toppings: 2

Enter topping number 1: ham

Enter topping number 2: onions

Order Summary:

Customer Name: tyler

2 large pizzas with ['ham', 'onions']

Subtotal | Sales Tax (6%) | Total Cost

26.2 | 1.5719999999999998 | 27.772

Explanation:

name = input("Name: ")

num_pizzas = int(input("Number of pizzas: "))

print("Small (10 inch, $7.95), Medium (12 inch, $9.95), and Large (14 inch, $11.95)")

pizza_size = input("Pizza size: ").lower()

print("Available toppings: Ham, Mushrooms, Onions, Green Peppers, Black Olives, Tomatoes, Pineapple, Spinach")

print("$0.75 each for Small Pizza, $0.95 each for Medium Pizza, and $1.15 each for Large Pizza")

num_toppings = int(input("Number of toppings: "))

toppings = []

subtotal = 0

tax = 0

total = 0

for i in range(1,num_toppings + 1):

toppings.append(input(f"Enter topping number {i}: "))

if pizza_size == 'small':

subtotal += num_pizzas * 7.95

subtotal += num_toppings * 0.75

tax += subtotal * 0.06

total += subtotal + tax

print("Order Summary: ")

print(f"Customer Name: {name}")

print(f"{num_pizzas} {pizza_size} pizzas with {toppings}")

print("Subtotal | Sales Tax (6%) | Total Cost")

print(f"{subtotal} | {tax} | {total}")

if pizza_size == 'medium':

subtotal += num_pizzas * 9.95

subtotal += num_toppings * 0.95

tax += subtotal * 0.06

total += subtotal + tax

print("Order Summary: ")

print(f"Customer Name: {name}")

print(f"{num_pizzas} {pizza_size} pizzas with {toppings}")

print("Subtotal | Sales Tax (6%) | Total Cost")

print(f"{subtotal} | {tax} | {total}")

if pizza_size == 'large':

subtotal += num_pizzas * 11.95

subtotal += num_toppings * 1.15

tax += subtotal * 0.06

total += subtotal + tax

print("Order Summary: ")

print(f"Customer Name: {name}")

print(f"{num_pizzas} {pizza_size} pizzas with {toppings}")

print("Subtotal | Sales Tax (6%) | Total Cost")

print(f"{subtotal} | {tax} | {total}")
