This lab is about looping through a list of lists to find specific data.

A list of lists has been created already which is what you will use.

The goal of this lab is to find if the customer is in the lists and if they are to update their recorded information and if applicable ask if they would like to redeem their free car wash reward.

Each list in the list of lists contains the following information in the corresponding order:

Customer$$s Name

Number of drinks purchased so far

First you should ask for the customer$$s name, using the following prompt: $($Note that every prompt in this lab should end with a newline$)$

Welcome, please input your name:

Once you find a customer, you will ask them how many drinks they bought today and update their drinks purchased info in their list. The prompt for asking for drinks purchased today is as follows:

How many drinks did you purchase today?

Once you have updated the drinks purchased, you will check if they have purchased $15$ or more drinks total $($today and previously$).$ If the customer has $15$ or more drinks then they are eligible for a free car wash and a message stating this should be printed. Otherwise, print how many more drinks the customer must purchase to get the free car wash.

The message for a free car wash is as follows:

Eligible for a free car wash!

If the customer is eligible, ask if they would like to redeem it using the following prompt:

Would you like to redeem your free car wash? $($y$/$n$)$

And if the customer inputs y then print out the following message using the excess drinks after subtracting $15$ from the number of drinks purchased:

After redeeming your free car wash, you have $\{$drinks remaining$\}$ drinks remaining towards your next free car wash.

And the message to print with how many more points a customer needs is as follows:

You are $\{$needed drinks$\}$ drinks away from a free car wash!

End every session with the following message:

Have a nice day!
