Crate xiangting 

A library for calculating the deficiency number (a.k.a. xiàngtīng number, 向聴数).

Example

// 123m456p789s11222z
let hand: [u8; 34] = [
    1, 1, 1, 0, 0, 0, 0, 0, 0, // m
    0, 0, 0, 1, 1, 1, 0, 0, 0, // p
    0, 0, 0, 0, 0, 0, 1, 1, 1, // s
    2, 3, 0, 0, 0, 0, 0, // z
];

let replacement_number = calculate_replacement_number(&hand, &PlayerCount::Four)?;
assert_eq!(replacement_number, 0u8);
