Deleting a specific element from a nested hash

Question

I am trying to work with a nested hash. I have a deck of cards represented as follows:

deck_of_cards = { :hearts => {:two => 2, :three => 3, :four => 4, :five => 5, :six => 6, :seven => 7, :eight => 8, :nine => 9, :ten => 10, :jack => 10,              :queen => 10, :king => 10, :ace => 11}, :spades => {:two => 2, :three => 3, :four => 4, :five => 5, :six => 6, :seven => 7, :eight => 8, :nine => 9, :ten => 10, :jack => 10,              :queen => 10, :king => 10, :ace => 11}, :clubs => {:two => 2, :three => 3, :four => 4, :five => 5, :six => 6, :seven => 7, :eight => 8, :nine => 9, :ten => 10, :jack => 10,              :queen => 10, :king => 10, :ace => 11}, :diamonds => {:two => 2, :three => 3, :four => 4, :five => 5, :six => 6, :seven => 7, :eight => 8, :nine => 9, :ten => 10, :jack => 10,              :queen => 10, :king => 10, :ace => 11} } 

My goal is to be able to remove one specific card from the deck and return the deck of cards without that specific card. Would anyone be able to help me on how to iterate through the hash and remove a card like the two of clubs?

deck_of_cards[:two][:clubs] 

This code works to remove a suit of cards, but I cant figure out how to remove a specific card

deck_of_cards.delete_if {|k, v| k == :spades} 

Answer 1

Just do this:

deck_of_cards[:clubs].delete(:two) 

Answer 2

You can remove an element and return the original hash also using tap function like this

deck_of_cards.tap{|d|    d[:hearts].tap{|h|      h.delete(:two)   } } 

this will return the deck_if_cards hash without :two key

you can do it in one line also

    deck_of_cards.tap{|d| d[:hearts].tap{|h| h.delete("two")}}
