/******************
* Name Matching
*
* At Checkr, one of the most important aspects of our work is accurately matching records
* to candidates. One of the ways that we do this is by comparing the name on a given record
* to a list of known aliases for the candidate. In this exercise, we will implement a
* `nameMatch` method that accepts the list of known aliases as well as the name returned
* on a record. It should return true if the name matches any of the aliases and false otherwise.
*
* The nameMatch method will be required to pass the following tests:
*
* 1. Exact match
*
* knownAliases = ["Alphonse Gabriel Capone", "Al Capone"]
* nameMatch(knownAliases, "Alphonse Gabriel Capone") => true
* nameMatch(knownAliases, "Al Capone") => true
* nameMatch(knownAliases, "Alphonse Francis Capone") => false
*
*
* 2. Middle name missing (on alias)
*
* knownAliases = ["Alphonse Capone"]
* nameMatch(knownAliases, "Alphonse Gabriel Capone") => true
* nameMatch(knownAliases, "Alphonse Francis Capone") => true
* nameMatch(knownAliases, "Alexander Capone") => false
*
*
* 3. Middle name missing (on record name)
*
* knownAliases = ["Alphonse Gabriel Capone"]
* nameMatch(knownAliases, "Alphonse Capone") => true
* nameMatch(knownAliases, "Alphonse Francis Capone") => false
* nameMatch(knownAliases, "Alexander Capone") => false
*
*
* 4. More middle name tests
* These serve as a sanity check of your implementation of cases 2 and 3
*
* knownAliases = ["Alphonse Gabriel Capone", "Alphonse Francis Capone"]
* nameMatch(knownAliases, "Alphonse Gabriel Capone") => true
* nameMatch(knownAliases, "Alphonse Francis Capone") => true
* nameMatch(knownAliases, "Alphonse Edward Capone") => false
*
*
* 5. Middle initial matches middle name
*
* knownAliases = ["Alphonse Gabriel Capone", "Alphonse F Capone"]
* nameMatch(knownAliases, "Alphonse G Capone") => true
* nameMatch(knownAliases, "Alphonse Francis Capone") => true
* nameMatch(knownAliases, "Alphonse E Capone") => false
* nameMatch(knownAliases, "Alphonse Edward Capone") => false
* nameMatch(knownAliases, "Alphonse Gregory Capone") => false
*
*
* Bonus: Transposition
*
* Transposition (swapping) of the first name and middle name is relatively common.
* In order to accurately match the name returned from a record we should take this
* into account.
*
* All of the test cases implemented previously also apply to the transposed name.
*
*
* 6. First name and middle name can be transposed
*
* "Gabriel Alphonse Capone" is a valid transposition of "Alphonse Gabriel Capone"
*
* knownAliases = ["Alphonse Gabriel Capone"]
* nameMatch(knownAliases, "Gabriel Alphonse Capone") => true
* nameMatch(knownAliases, "Gabriel A Capone") => true
* nameMatch(knownAliases, "Gabriel Capone") => true
* nameMatch(knownAliases, "Gabriel Francis Capone") => false
*
*
* 7. Last name cannot be transposed
*
* "Alphonse Capone Gabriel" is NOT a valid transposition of "Alphonse Gabriel Capone"
* "Capone Alphonse Gabriel" is NOT a valid transposition of "Alphonse Gabriel Capone"
*
* knownAliases = ["Alphonse Gabriel Capone"]
* nameMatch(knownAliases, "Alphonse Capone Gabriel") => false
* nameMatch(knownAliases, "Capone Alphonse Gabriel") => false
* nameMatch(knownAliases, "Capone Gabriel") => false

/*
Part 1:
* this is a two player card game
* the game starts with a deck of 52 cards represented as
unique integers [1...52]
* the cards are randomly shuffled and then dealt out to both players evenly.
* on each turn:
* both players turn over their top-most card
* the player with the higher valued card takes
the cards and puts them in their win pile
(scoring 1 point per card)
* this continues until all the players have no cards left
* the player with the highest score (number of cards in their win pile) wins.
* if they have the same number of cards in their win pile, tiebreaker goes to the player with the highest card in their win pile.
Be able to play the game with N players.
An input to the game will now be a list of strings (of length N) indicating the player names.
The deck contains M cards of distinct integers.
It is not guaranteed M % N == 0. If there are leftover cards they should randomly be handed out to remaining players.
i.e. with 17 cards and 5 people: 2 people get 4 cards and 3 get 3 cards
For example the input: game(["Joe", "Jill", "Bob"], 5) would be a game between 3 players and 5 cards.
you should print the name of the player that won the game.
