Provides code to show start and end index for each element in a list

readme.md

This code works but it can be improved.

Container.cs

public class Container<T>
{
    public T? Value { get; set; }
    public Index StartIndex { get; set; }
    public Index EndIndex { get; set; }
}

Execute.cs

var Months = DateTimeFormatInfo.CurrentInfo.MonthNames[..^1].ToList();
var containers = Months.Get();
foreach (var container in containers)
{
    Debug.WriteLine($"{container.StartIndex,-4}{container.EndIndex,-4}{container.Value}");
}

RangeHelpers.cs

public static class RangeHelpers
{
    public static List<Container<T>> Get<T>(this List<T> list) =>
        list.Select((element, index) => new Container<T>
        {
            Value = element,
            StartIndex = new Index(index),
            EndIndex = new Index(Enumerable.Range(0, list.Count).Reverse().ToList()[index], true)
        }).ToList();
}
