Resolves #143 This draft PR implements the `Debug` trait for `LazySegtree`. As mentioned in the issue, the `Debug` implementation uses the `debug_struct` function to display the relevant fields. I would...

Resolves #145 This draft PR implements the `Debug` trait for `FenwickTree`. The previous draft PR with the same content was unintentionally closed, so I’ve created a new branch to both...

Implement `Clone` and `Debug` for `FenwickTree`

12

Implement the `Clone` and `Debug` traits for `FenwickTree`. For the `Clone` trait, it should be enough to add a `Clone` trait bound to `T` and write an explicit `impl`. For...

Implement `Clone` for `LazySegtree` and discuss the `Debug` Implementation

2

Implement the `Clone` trait for `LazySegtree`. Since both `MapMonoid::F` and `::S` have the `Clone` constraint, it can be derived. Additionally, `LazySegtree` already has a `Debug` implementation, but there is a...

Implement `Clone` and `Debug` for `Segtree`

2

Implement the `Clone` and `Debug` traits for `Segtree`. Since `M::S` has the `Clone` constraint, the `Clone` trait can be derived. For the `Debug` trait, I propose adding `use std::fmt::{Debug, Error,...

Arithmetic operations between primitive and modint

It would be convenient if we could `u32 + Modint`, and so on.
