WebDuality of sort and hash •Divide-and-conquer paradigm •Sorting: physical division, logical combination •Hashing: logical division, physical combination •Handling very large inputs •Sorting: multi-level merge •Hashing: recursive partitioning •I/O patterns •Sorting: sequential write, random read (merge) WebMar 13, 2012 · Hashes can sometimes be cached, if there is enough room in the data structure where the key is stored; caching the result of comparisons (a binary operation) is often impractical. On the other hand, comparisons can benefit from shortcutting: if keys often differ within the first few bytes, a negative comparison can be very fast.
