SeekAGeek has been a huge hit, and the Greek Geek is now the proud owner of a platform that is receiving ample attention from many geeks. He owns a super$-$geeky cafe as a side hustle $-$ The Caffeinated Geek $-$ which sells beverages in a geek$-$friendly environment. Recently, he decided to advertise The Caffeinated Geek on SeekAGeek, in a clever attempt to take advantage of his large geek audience. It's been a huge success $-$ many geeks have enjoyed their first date at The Caffeinated Geek, but there is one hiccup: geeks are shy and don't like coming up to the counter to place their orders. As such, he has decided to install several self$-$help kiosks that allow geeks to search his menu at their own pace and place an order. He has sent you the following message:

Hi$!$ I have another project for you. I want you to create an app that geeks can use to search my beverages menu based on their main ingredients, i$.$e$.,$ type of milk $($or no milk$),$ sugar$/$no sugar, number of shots, and extras. I only stock the following milks: WHOLE, SKIM, SOY, ALMOND, and OAT. My extras range varies, depending on what I can buy in$,$ but generally includes syrups, ice cream, cream, etc. Users MUST be able to choose one or more extras or skip extras altogether.

I want users to be able to view all the menu items that meet their search criteria in the following format:

Mocha $(30213)$

Rich espresso mixed with steamed almond milk and topped with whipped cream and chocolate syrup.

Ingredients:

Number of shots: $2$

Sugar: yes

Milk options: Almond, Full$-$cream

Extra$/$s: Whipped cream, Vanilla ice cream, Chocolate syrup, Chocolate powder

Price: $$5\mathrm{.}50$

Users MUST be able to choose any item on my menu. If they want to place an order, they must provide their full name, as well as their phone number $($which will be used as their order number$).$ Their order details should be written to a file in the following format:

Order details:

Name: Dr$.$ Walter Shepman

Order number: $0486756465$

Item: Mocha $(30213)$

Milk: Full$-$cream

If their search doesn't return any matches, please let them know!
