Q1 Function that takes in a List and a String name, and returns a List of all the customers that have visited a business with the name (where business.name equals String name)

-- solved using streams

Q2 Function that takes in a List and returns a List of all the people that are owners that are customers of their own business (where business.customers contains business.owner)

-- solved using streams

Q3 Function that takes in a List and returns a List that is a *distinct* list of every pet of all the customers

-- solved using streams

Q4 Function that takes in a List and returns a Map where the key is the owner and the value is the business the owner owns (you may assume the owners in the list only own a single business)

-- solved using streams

Q5 Function that takes in a List and a Map (key == business.name, value == revenue) and returns a Map (key = owner, value = revenue) (you may assume the owners in the list only own a single business)

-- solved using streams

Q6 function that takes in an Integer n and Recursively turns the number into its string representation as you would say the number, e.x 878444 => "eight hundred seventy eight thousand four hundred forty four"

*you can assume that n will always be less than one million (n<=999,999) and positive *-2 points if this is not solved with recursion

Q7 recursive function called multiply takes in an integer a and an integer b, and returns the product of (a, b) using only addition (you can assume a,b are always positive)

-2 points if this is not solved with recursion

Q8 unit test for Q1->3 + Q7

Q1 sample input

[ {name : walmart,

address: some lane,

owner: joe

postalCode: n9n0a5

{name : freshie,

address: some other lane,

owner: joe postalCode: n9n0a5

customers: [{name: jill, age 25, pets :[{name : goldie, age: 3, type : fish}]}]

}
