Kollisionsstrategi
Kollisionsstrategi, often translated as collision strategy or collision handling, is a fundamental concept in computer science, particularly in the field of data structures. It refers to the methods employed to resolve conflicts that arise when two or more keys or data items attempt to occupy the same location within a data structure, most commonly a hash table. When a hash function maps different keys to the same index or bucket, a collision occurs. Without a proper strategy, this would lead to data loss or incorrect retrieval.
There are two primary categories of collision strategies: open addressing and separate chaining. In open addressing,
Separate chaining, on the other hand, handles collisions by creating a secondary data structure, typically a
