It has a time complexity of O(logn) for both updates and range sum queries. Fenwick trees were first described in a 1994 paper by Peter M. Fenwick titled "A new data structure for cumulative frequency …

WebJul 18, 2024 · Using the image above as an example: middle element = 23 to_search = 4 if 23 > 4. we move to the left side because all numbers less than 23 are stored there. index (23) = 2. new_position = index (23) - 1 = 2-1 = 1. The search will end at index 1 and take all other value (s) before index 1. WebA B+ tree is an advanced form of a self-balancing tree in which all the values are present in the leaf level. An important concept to be understood before learning B+ tree is multilevel indexing. In multilevel indexing, the index of indices is created as in figure below.
