Deck of Cards Shuffling

You are given a list containing multiple decks of cards, where each deck consists of 52 unique cards. The total number of cards, n, is guaranteed to be a multiple of 52. Each card is represented as a structure containing two fields: suit and rank. Write a function to shuffle all the cards together using a custom algorithm that mimics manual shuffling. Constraints

• The total number of cards, n, is guaranteed to be a multiple of 52, indicating that there are multiple decks.
• Each card has a suit and a rank.
• Suits are one of "Hearts", "Diamonds", "Clubs", "Spades".
• Ranks are one of "A", "2", "3", ..., "10", "J", "Q", "K". Function Signature std::list<Card> shuffleAllDecks(const std::list<Card>& all_decks); Input The input all_decks is a std::list of Card structures containing one or more decks of cards. All the decks are combined into a single list for shuffling. Output Return a std::list<Card> where all the cards from the input have been shuffled together.
