C# Sharp: Basic Algorithm Exercises - Create a new list from a given list of integers where each element is multiplied by 3

Sample Solution:

C# Sharp Code:

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

namespace exercises
{
   class Program
    {       
        static void Main(string[] args)
        {    
           List<int> mylist = test(new List<int>(new int[] { 1, 2, 3 , 4 }));                  
           foreach(var i in mylist)
            {
               Console.Write(i.ToString()+" ");
            }     
        }                  
        public static List<int> test(List<int> nums)
          {
            IEnumerable<int> doubled = nums.Select(x => x *= 3);
            return doubled.ToList<int>();
          }    
    } 
}

Sample Output:
