Given an array A on N entries, the range minimum query (RMQ) rmq(i, j), such that 1 ≤ i ≤ N, asks for the item in the range A[i..j] with the smallest.
We introduce a way of using the Binary Indexed Trees so that we can answer different types of queries, e.g. the range minimum query, in O (log N ) time ...
In this paper we study the offline (batched) range minima query (RMQ) problem in the external memory (EM) and cache-oblivious (CO) models.
