✐ Examples

1 Rotate Elements in a List of Integers

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        List<int> numbers = new List<int> { 1, 2, 3, 4, 5 };
        int distance = 2;
        numbers.Rotate(distance);
        Console.WriteLine("Rotated list: " + string.Join(", ", numbers));
    }

    static void Rotate<T>(this List<T> list, int distance)
    {
        list.InsertRange(0, list.GetRange(list.Count - distance, distance));
        list.RemoveRange(list.Count - distance, distance);
    }
}

Rotated list: 4, 5, 1, 2, 3

2 Rotate Elements in a List of Strings

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        List<string> words = new List<string> { "apple", "banana", "cherry", "date", "elderberry" };
        int distance = 3;
        words.Rotate(distance);
        Console.WriteLine("Rotated list: " + string.Join(", ", words));
    }

    static void Rotate<T>(this List<T> list, int distance)
    {
        list.InsertRange(0, list.GetRange(list.Count - distance, distance));
        list.RemoveRange(list.Count - distance, distance);
    }
}

Rotated list: date, elderberry, apple, banana, cherry
