1. adjust_quantities
You have the ingredient list of a one-person recipe. You want to cook it for many persons (defined by

1. nb_persons

复制代码

). So, you must multiply all the quantities.
The ingredient list consists of strings, each defining a specific product. They all have the following format:

• An integer (written with digits), defining the quantity.
• A space character.
• Some words, defining the product.

Modify the string by multiplying the initial integer by

1. nb_persons

复制代码

.
You do not have to take care of the singular/plural of the words defining the product. These words may contain some numbers, you must not modify them.
The order of the lines must be preserved.
Example
You want to cook a cake for 3 persons. Here is the initial ingredient list for one person:
2 eggs
200 grams of flour
150 grams of sugar
1 liter(s) of milk
You must output this list:
6 eggs
600 grams of flour
450 grams of sugar
3 liter(s) of milk

AI follow-up
In your loop, when a guest ID is found in

1. waiting

复制代码

, you remove that guest from the queue rather than moving them into

1. seated

复制代码

. What situation in the input does this branch represent, and how does your code distinguish it from a guest's departure after being seated?
