Fenwick Tree
By LeCalin, history, 7 years ago, In English

Hello Codeforces.

Today I read about Fenwick tree. Correctly update in range and find sum in range. Update in range, it means adding value to the range. Can we set value in range and find sum in range with fenwick tree?

Sorry for my English.

      Sorry, but in Fenwick Tree you can't update in range. But you can use Segment Tree. In Segment Tree you can do nearly anything.
