23rd Annual Symposium on Foundations of Computer Science (FOCS 1982)
Storing a sparse table with O(1) worst case access time
November 03-November 05
We describe a data structure for representing a set of n items from a universe of m items, which uses space n+o(n) and accommodates membership queries in constant time. Both the data structure and the query algorithm are easy to implement.
