Implementing Hash Tables and String Rolling Hashes in C++
A hash table delivers expected O(1) time complexity for data retrieval and insertion by mapping arbitrary keys into a fixed-size array. This technique compresses a large key space (e.g., integers up to 10^9) into a manageable index range (typically 10^5 to 10^6). Unlike discretization, which preserves relative order, hashing focuses solely on e ...
