Disadvantages of Hashing
- Collisions: Different elements can have the same hash code, requiring collision handling techniques (e.g., chaining, double hashing) which can impact performance.
- Not a good fit for all problems: Not suitable for problems requiring frequent updates or deletions.
- Choosing the right hash function: Important to select a good hash function to minimize collisions.
Hashing in Competitive Programming
Hashing is a fundamental technique in competitive programming that is used to efficiently manipulate and process large amounts of data. Data Structures like Hash Maps and Hash Sets use hashing techniques to provide faster insertion, deletion and retrieval of values.
