Write a program to cyclically rotate an array by one in C#

// C# code for program to cyclically // rotate an array by one using System;   public class Test {     static int[] arr = new int[] { 1, 2, 3, 4, 5 };       // Method for rotation     static void rotate()     {         int last_el = arr[arr.Length - 1], i;           for (i = arr.Length - 1; i > 0; i--)             arr[i] = arr[i - 1];           arr[0] = last_el;     }       // Driver Code     public static void Main()     {         Console.WriteLine("Given Array is");         string Original_array = string.Join(" ", arr);         Console.WriteLine(Original_array);           // Function Call         rotate();           Console.WriteLine("Rotated Array is");         string Rotated_array = string.Join(" ", arr);         Console.WriteLine(Rotated_array);     } }   // This code is contributed by vt_m.

Output

Given array is 
1 2 3 4 5 
Rotated array is
5 1 2 3 4
