.select() in c#

Comment

//First import LINQ
using System.Linq;

//Used to transform all elements in a list.
int[] arr = [1, 3, 5, 6];
int y = 3;
arr.Select(x => x * y).ToArray();
//used .ToArray() to copy it back into the original array.
//arr now equals [3, 9, 15, 18];
//Learn more by looking into LINQ; worth it if you have never heard of it.
