Old Elyse's Enchantments
10 Points
As a magician-to-be, Elyse needs to practice some basics. She has a deck of cards that she wants to manipulate.
To make things a bit easier she only uses the cards 1 to 10.
1. Retrieve a card from a deck
Return the card at position idx from the given deck.
julia> idx = 2;
julia> card([1, 3, 4, 1], idx)
32. Exchange a card in the deck
Exchange the card at position idx with the new card provided and return the adjusted deck.
Note that this will mutate (change) the input vector and this is okay.
julia> idx = 2; new_card = 6;
julia> replace_card!([1, 3, 4, 1], idx => new_card)
[1, 6, 4, 1]3. Insert a card at the of top the deck
Insert new card at the top of the deck and return the deck.
julia> new_card = 8;
julia> insert_card_at_top!([1, 3, 4, 1], new_card)
[1, 3, 4, 1, 8]4. Remove a card from the deck
Remove the card at position idx from the deck and return the deck.
julia> idx = 2;
julia> remove_card!([1, 3, 4, 1], idx)
[1, 4, 1]5. Remove the top card from the deck
Remove the card at the top of the deck and return the deck.
julia> remove_card_from_top!([1, 3, 4, 1])
[1, 3, 4]6. Insert a card at the bottom of the deck
Insert a new card at the bottom of the deck and return the deck.
julia> new_card = 8;
julia> insert_card_at_bottom!([1, 3, 4, 1], new_card)
[8, 1, 3, 4, 1]7. Remove a card from the bottom of the deck
Remove the card at the bottom of the deck and return the deck.
julia> remove_card_at_bottom!([1, 3, 4, 1])
[3, 4, 1]8. Check size of the deck
Check whether the size of the deck equals a given deck_size or not.
julia> deck_size = 4;
julia> check_deck_size([1, 3, 4, 1], deck_size)
true
julia> check_deck_size([1, 3, 4, 1, 5], deck_size)
