D. yet another range query problem
WebArray range queries are of current interest in the field of data structures. Given an array of numbers or arbitrary elements, the general array range query problem is to build a data … WebInstead, we can generate some useful information about each index in O ( n) and then solve each query in O ( 1). Let d p i = ∑ k = 0 i A k. Thus, ∑ k = i j A k = d p j − d p i − 1. Stop and think about why this is true (it is very important that you understand this). Also, think about why you need to watch the i = 0 case!

WebWith that out of the way, the sample problem we are trying to solve is the following: given an sequence of N numbers, execute two kinds of queries: update (increase the value at some index by some value) and query (print the sum of all numbers up to some position). WebOne query is to find minimum value in a given range and the other query is to update an element at a given index. The update operation changes the minimum element in involved ranges which makes this a difficult problem. In this article, we have solved this problem using Segment Tree and this takes O (log N) time for both update and range query.
