What is the role of hashing in data structures?

Can you explain what hashing is in the context of data structures?

Hashing is a technique used to convert data into a fixed-size value or key, which helps in efficient data retrieval.

Why is hashing important for data structures like hash tables?

Hashing allows for quick data access and retrieval, making operations like search, insert, and delete much faster.

Are there any downsides to using hashing?

Yes, potential downsides include hash collisions, where different inputs produce the same hash, and the need for a good hash function.

How do hash collisions affect performance?

Hash collisions can lead to longer search times and reduced efficiency, as multiple entries may need to be checked.
