and calculate prefix sums in a table of numbers.

Methods
impl<T: Copy + AddAssign + Sub<Output = T>> FenwickTree<T>[src]
pub fn new(size: usize, init: T) -> FenwickTree<T>[src]
Constructs a new FenwickTree. The size of FenwickTree should be specified by size.
pub fn add(&mut self, k: usize, value: T)[src]
pub fn sum(&self, l: usize, r: usize) -> T[src]
Returns a sum of range [l, r)
pub fn sum_one(&self, k: usize) -> T[src]
Returns a sum of range [0, k)
