Output ranking

The Ranking<T> component represents a sorted structure IReadOnlyCollection<T> of alternatives, ordered from best to worst based on their scores. It implements the IEnumerable<T> interface, allowing it to be iterated over.

public sealed record Ranking<T> : IEnumerable<RankingRow<T>> 
    where T : IComparable<T>
{
    private readonly IReadOnlyCollection<RankingRow<T>> _rows;

    public Ranking(IEnumerable<RankingRow<T>> rows)
    {
        _rows = rows.ToArray();
    }
    
    public IReadOnlyCollection<RankingRow<T>> RankingItems 
        => _rows;
    
    public IEnumerator<RankingRow<T>> GetEnumerator()
        => RankingItems.GetEnumerator();

    IEnumerator IEnumerable.GetEnumerator()
        => GetEnumerator();
}

A Ranking exposes a ranking rows. Each row represents one alternative and contains

public sealed record RankingRow<T>
    where T : IComparable<T>
{
    public int AlternativeIndex { get; }
    public int Rank { get;  }
    public T Score { get; }
}

• Alternative: A unique number identifying the option.
• Rank: The position in the list (1 = best).
• Score: A numeric value showing how well the option performed.
