Question
In the context of searching, what is the primary
advantage of using hashing?Solution
Hashing provides an average-case time complexity of O(1) for search, insertion, and deletion operations. While collisions can degrade performance to O(N) in the worst case, a good hash function and collision resolution strategy keep the average performance very high. It does not guarantee O(1) worst-case, nor is it inherently good for range queries or preserving order. It also typically requires extra space for the hash table itself.
