Answer 1

using System;
using System.Linq;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        string s = "Would you like to know more? (Explore and learn)";
        int n = 2;

        string result = MoveNthWordToEndOfString(s, n);

        Console.WriteLine(result);
    }

    public static string MoveNthWordToEndOfString(string input, int n)
    {
        if (string.IsNullOrWhiteSpace(input))
            return input;

        List<string> parts = input
            .Split(new[] { ' ' }, StringSplitOptions.RemoveEmptyEntries)
            .ToList();

        if (n < 0 || n >= parts.Count)
            throw new ArgumentOutOfRangeException(nameof(n), "Index is out of range.");

        string word = parts[n];
        parts.RemoveAt(n);
        parts.Add(word);

        return string.Join(" ", parts);
    }
}
