WebA Fenwick Tree (a.k.a. Binary Indexed Tree, or BIT) is a fairly common data structure. BITs are used to efficiently answer certain types of range queries, on ranges from a root to some distant node. They also allow quick updates on individual data points. http://duoduokou.com/algorithm/17627396641353690871.html

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.
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.
