Binary indexed tree basic c++
WebImplementation of a Binary Indexed Tree (a.k.a. Fenwick tree) in C++ - BIT.cpp WebAn indexed binary tree can be represented as an array or a tree. For simplicity, we will represent it as a tree. To obtain the parent of a node with index i: Covert i to binary. Flip the rightmost bit containing 1 to 0. For all nodes with an index greater than zero: Express the index in terms of the sum of powers of 2.
