Shopping List Menu

This program runs a small menu in a loop: 1 adds an item to a shopping list, 2 shows the list, 3 leaves, and any other choice is unknown. Its lines are mixed up: put them back in an order that prints exactly the output below. Each block keeps its indentation, so you only choose the order.

Example

The program reads these lines, one at each input():

1
milk
1
bread
2
5
3

In the right order, it prints:

Added milk
Added bread
List: milk, bread
Unknown choice
Bye
