This structure was proposed by Boris Ryabko in 1989 with a further modification published in 1992. It has subsequently become known under the name Fenwick tree … See more Given a table of elements, it is sometimes desirable to calculate the running total of values up to each index according to some associative binary operation (addition on integers being by far the most common). Fenwick trees … See more A Fenwick tree is most easily understood by considering a one-based array $${\displaystyle A[n]}$$ with $${\displaystyle n}$$ elements. … See more • Order statistic tree • Prefix sums • Segment tree See more • A tutorial on Fenwick Trees on TopCoder • An article on Fenwick Trees on Algorithmist • An entry on Fenwick Trees on Polymath wiki See more
