Question
Collisions can be completely avoided in a hash table by choosing a perfect hash function.
- Group of answer choices
- True
- False
Solution
Analysis of the Statement
-
Understanding Hash Functions: A hash function is designed to map data of arbitrary size to fixed-size values. In the context of hash tables, it is used to convert keys into indices of an array.
-
What is a Perfect Hash Function: A perfect hash function is one that assigns unique indices to each key, ensuring that no two keys hash to the same index, thus eliminating collisions.
-
Implications of a Perfect Hash Function: If a perfect hash function is used, every key will be mapped to a unique value in the hash table, thereby avoiding any possibility of collision.
Conclusion
Based on the definition and characteristics of a perfect hash function, the statement "Collisions can be completely avoided in a hash table by choosing a perfect hash function" is correct.
Final Answer
True
