Binary indexed tree codeforces

Alright, so this is my 2nd post here. The 1st one, as you can see, was written in Vietnamese – my mother tounge, just because I thought that CodeForces Blog A Binary Indexed Tree (BIT) is used to store cumulative sums. You have an array a 0, a 1,, a n. You want to be able to retrieve the sum of the first k elements in Hey guys, can you please give me some sources with easy BIT 2D implementation? I would be grateful also for some problems using this from easy to hard. Hi everyone, I've written the following Fenwick tree tutorial because I've found many other tutorials to be fenwick tree, binary indexed tree, range query. How can I quickly identify a particular problem can easily be solved by BIT? What kinds of problems can be solved by BIT other than range sum calculation

This is to share the explanation of the BIT and the meaning of the bit operations. public class NumArray { /** * Binary Indexed Trees (BIT or Fenwick tree):
