What are all the types of shuffling?

Shuffling can refer to various methods of rearranging items, commonly in the context of cards or data. The main types include the riffle shuffle, where cards are split and interleaved, the overhand shuffle, which involves taking small groups of cards from one hand and placing them over another, and the pile shuffle, where cards are dealt into piles. Additionally, in data processing, shuffling can involve algorithms like the Fisher-Yates shuffle to randomize arrays or lists. Each method serves different purposes depending on the desired randomness and efficiency.
