Introduction to Fenwick Tree/Binary Indexed Tree(BIT)

Web5 Mar 2024 · In a Fenwick tree, a certain cell is responsible for other cells as well. The position of the first non-zero bit from right in the binary representation of the index of the cell determines the range of responsibility of that cell below itself. Let’s call this position RSB (rightmost set bit). Web24 Dec 2024 · Pull requests. This project implements the **Binary Indexed Tree** with template. It can obtain the prefix sum in O (log N) time, add or update one item in O (log N) time, random-access in O (1) time. At the same time, we provide a **random access iterator** of the prefix sum. The iterator can interact well with many STL algorithms. Web2 Apr 2011 · 2 Answers.
