Tree data structuresUpdating and querying on a range is a classical algorithmic problem with a multitude of applications. The Segment Tree data structure is particularly notable in handling the range query and

Hi,TLDR: Can I solve all kinds of range query questions (the kind with N, Q<= 100,000) by just studying Segment trees??(O(logn) query and update questions) My knowledge till now tells me that Segment trees can be used for range query problems, I haven't found any other application...
Hello, Recently, I've been learning about the persistent segment tree. However, is there a way to get a persistent segment tree with range updates, and not just point updates? If so, can someone direct me to a clean and easy implementation in C++? Thanks! -dx24816...
You may assume the number of calls to update and sumRange function is distributed evenly. 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...
REMIX: Efficient Range Query for LSM-trees 原文地址 LSM-tree 的强大写入性能使得很多知名的 KV 存储都选择了它作为底层实现,比如 LevelDB、RocksDB 等。但在充分利用磁盘顺序写入提高写入性能的同时,它的查询效率也受到了比较大的影响,一次查询往往需要访问多个 table 文件。对于点查还可以通过bloom filter来做缓...
