Sparse Table for Range Minimum/Maximum Query

Range Minimum/Maximum Query (RMQ) The RMQ problem involves finding the minimum or maximum value within a specified range of an array of length n. Given multiple queries of the form RMQ(A, i, j), where i and j are indices in the array, the task is to return smallest or largest element between positions i and j. Sparse Table Algorithm The Sparse ...
