What are the benefits of the data structure "Union Find Disjoint"?
Step by step
Solved in 2 steps
- What are the advantages of the "Union Find Disjoint" data structure?use c++ language You run an e-comměrce website and want to record the last N order ids in a log. Implement a data structure to accomplish this, with the following API: record(order_id): adds the order_id to the log get_last(i): gets the ith last element from the log. i is guaranteed to be smaller than or equal to N. You should be as efficient with time and space as possible.Best Practices to Follow: It’s worth breaking up each functional task in create_blackjack_game() into separate functions. For example, a function to check the score of a player’s hand, to check whether a player has won, and so on. This entire implementation can be done neatly in about eight functions. Create a Deck of Cards Complete the create_standard_deck() function, which creates a new deck. The deck itself must be a data structure list. The cards within the deck must be represented as tuples of the form (suit, number), where the suit is a string that must be either ‘hearts’, ‘clubs’, ‘spades’, or ‘diamonds’, and the number is an integer that must be one of the following: 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, or 14. Note that the number used to identify the card has the following association: Jack = 11, Queen = 12, King = 13, and Ace = 14. In terms of value, the picture cards (Jack, Queen, and King) all have a value of 10, and the Ace card has a value of 11. The casino only wants…

- What is the main difference between UNION and UNION ALL?At what point is it appropriate to build an index by hand?Coding language: C++. (Try to avoid linked lists if possible please). Add comments. Thanks. • Each functionality component must be implemented as a separate function, though the function does not need to be declared and defined separately • No global variables are allowed • No separate.hor.hpp are allowed • You may not use any of the hash tables, or hashing functions provided by the STL or Boost library to implement your hash table • Appropriate, informative messages must be provided for prompts and outputs You must implement a hash table using the Double Hashing collision strategy and the mid-square base 10 hashing function with an R of 2. Your collision strategy must be implemented as a separate function, though it may be implemented inside your insert/search/delete functions, and should halt an insert / search/delete functions, and should halt an insert/search/delete after table size number of collisions. Your hash function must be implemented as a separate function. Your hash table…
