What are the performance differences between sets and arrays in programming?
Sets and arrays have different performance characteristics. Sets offer faster lookups and insertions, while arrays are better for indexed access.
Can you explain why sets are faster for lookups?
Sets use hash tables for storage, allowing for average O(1) time complexity for lookups, while arrays require O(n) in the worst case.
What about memory usage? Are sets more memory-intensive than arrays?
Yes, sets can be more memory-intensive due to the overhead of maintaining a hash table, while arrays have a more compact memory layout.
In what scenarios should I prefer using arrays over sets?
Use arrays when you need ordered data, indexed access, or when the size is fixed. They are also more memory-efficient for small datasets.
