Fenwick Tree or Binary Indexed Tree is a data structure used to calculate range queries along with updating the elements of the array, such that each query or update takes logarithmic time complexity. It is used to calculate prefix sums or running total of values up to any index.
Fenwick Tree (Binary Indexed Tree) for Competitive Programming
In the world of competitive programming, speed is everything. Fenwick Tree (also known as Binary Indexed Tree), created by Peter M. Fenwick. They’re like secret weapons for programmers, especially when you need to quickly find cumulative frequencies in problem-solving. This article breaks down Fenwick Trees in simple terms—how they’re built and why they’re handy for competitive programming. Whether you’re starting out or a pro looking for a speed boost, Fenwick Trees could be your key to success in coding competitions. Let’s dive in!
