/// Represent classical realization of Fenwiсk tree or Binary Indexed tree. WebHere we will discuss how to solve this problem using binary indexed tree (BIT). BIT is popularly known as fenwick tree. Intuitive steps Scatter - Calculate number of available seats till maxRow. - Return false if allotted seats + k > total seats - Else iterate through each row and allocate seats until k = 0 starting from start.

WebFeb 21, 2024 · Video. Binary Indexed Tree (BIT), also known as Fenwick Tree, is a data structure used for efficiently querying and updating cumulative frequency tables, or prefix … WebIntuitively, you can think of a binary indexed tree as a compressed representation of a binary tree that is itself an optimization of a standard array representation. This answer goes into one possible derivation. Let's suppose, for example, that you want to store cumulative frequencies for a total of 7 different elements. church men\\u0027s ministry
