Binary indexed tree vnoi

This binary indexed tree does all of this super efficiently by just using the bits in the index. The key trick is the following property of this perfect binary tree: Given node n, the next node on the access path back up to the root in which we go right is given by taking the binary representation of n and removing the last 1.

This binary indexed tree does all of this super efficiently by just using the bits in the index. The key thing behind the efficiency of BIT is: Given any index n, the next node on the path from root to that index where we go right is directly calculated by RESETing i.e. '0' the last (right most) SET-bit from the binary representation of index
