My knowledge till now tells me that Segment trees can be used for range query problems, I haven't found any other application yet (O(logn) query and update) Context: I have some interviews lined up in coming days, I have studied the Segment tree from Codeforces guide and have got some ...

First, let's consider 2 following types of queries on a sequence x[0]..x[n-1] inO(logn): sum(a, b)— calculate x[a] + x[a+1] + ... + x[b] add(i, value)— x[i] += value This is a well-known problem that can be solved usingFenwick tree. What is good with Fenwick...

Introduction of Segment Tree:http://www.geeksforgeeks.org/segment-tree-set-1-sum-of-given-range/ Time Complexity: Time Complexity for tree construction is O(n). There are total 2n-1 nodes, and value of every node is calculated only once in tree construction. ...

The segment tree can be computed in linear time and allows both queries and updates to be answered in time. It also allows, with some cleverness, entire ranges to be updated at once (efficiently). Analysis of the average case is left as an exercise to the reader. We can also use any...
without a sparse doc values index, using standard doc values, an inverted index on thehost.namefield and a KDB tree for the@timestampfield. It mirrors LogsDB queries from our Rally nightly benchmarks, where latency regressions appeared after introducing sparse doc value indices. By isolating th...
It can, of course, be solved by building an aggregation tree for all the sensors for each queried segment of the road. However, multiple queries will redo a lot of the same aggregations, and repeatedly transmitting detailed traffic data can be expensive. Thus we proceed as follows. ...
