How to Rotate Elements in an Array in C# - Step by Step Examples



How to Rotate Elements in an Array in C# ?

Answer

To rotate elements in an array using C#, you can implement a custom rotation function that shifts elements by a specified number of positions.



✐ Examples

1 Rotate Array of Integers

In this example,

  1. We have an array named intArray containing integers.
  2. We implement a custom RotateArray method that shifts elements by a specified number of positions.
  3. We print the rotated array to demonstrate the rotation.

C# Program

using System;
using System.Linq;

class Program
{
    static void Main()
    {
        int[] intArray = { 1, 2, 3, 4, 5 };
        int positions = 2;
        int[] rotatedArray = RotateArray(intArray, positions);
        Console.WriteLine("Rotated Array: [" + string.Join(", ", rotatedArray) + "]");
    }

    static int[] RotateArray(int[] array, int positions)
    {
        positions %= array.Length;
        Array.Reverse(array, 0, array.Length);
        Array.Reverse(array, 0, positions);
        Array.Reverse(array, positions, array.Length - positions);
        return array;
    }
}

Output

Rotated Array: [4, 5, 1, 2, 3]

2 Rotate Array of Strings

In this example,

  1. We have an array named strArray containing strings.
  2. We implement a custom RotateArray method that shifts elements by a specified number of positions.
  3. We print the rotated array to demonstrate the rotation.

C# Program

using System;
using System.Linq;

class Program
{
    static void Main()
    {
        string[] strArray = { "apple", "banana", "cherry", "date", "fig" };
        int positions = 3;
        string[] rotatedArray = RotateArray(strArray, positions);
        Console.WriteLine("Rotated Array: [" + string.Join(", ", rotatedArray) + "]");
    }

    static string[] RotateArray(string[] array, int positions)
    {
        positions %= array.Length;
        Array.Reverse(array, 0, array.Length);
        Array.Reverse(array, 0, positions);
        Array.Reverse(array, positions, array.Length - positions);
        return array;
    }
}

Output

Rotated Array: [date, fig, apple, banana, cherry]
