# Keta

A lightweight, zero-dependency Rust crate for digit operations, designed for competitive programming (AtCoder, etc.).

## Features

- **Zero Dependencies**: Depends only on `std`. Fast compile times.
- **Digit Manipulation**: Easily decompose numbers into digits (`digits()`), sum them (`digit_sum()`), or reverse them (`reverse()`).
- **Radix Support**: Handle binary, octal, hexadecimal, or any base-N operations (`digits_radix(2)`).
- **Competitive Programming Ready**: Optimized for speed, perfect for problems involving digit sums, palindromes, or base conversion.

## Installation

Add this to your `Cargo.toml`:

```toml
[dependencies]
keta = "0.1.0"
```

## Usage

```rust
use keta::Keta;

fn main() {
    // 1. Basic digit operations
    let n = 12345;
    assert_eq!(n.digits(), vec![1, 2, 3, 4, 5]);
    assert_eq!(n.digit_sum(), 15);
    assert_eq!(n.reverse(), 54321);

    // 2. Radix support (Base-2)
    let m = 6;
    assert_eq!(m.digits_radix(2), vec![1, 1, 0]); // 6 in binary is 110
    assert_eq!(m.digit_sum_radix(2), 2);          // 1 + 1 + 0 = 2

    // 3. Palindrome check
    assert!(12321.is_palindrome());
}

```
