How to Perform Right Circular Rotation of an Array in C#

In this article, I am going to discuss How to Perform Right Circular Rotation of an Array in C# with an example. Please read our previous article where we discussed How to Perform Left Circular Rotation of an Array in C# with an example.

Program Description:

Here, the user will input a one-dimensional integer array. Then we need to shift each element of the array to its right by one position in a circular fashion. The logic that we need to implement should iterate the loop from 0 t0 Length – 1 and then swap each element with the first element. Please have a look at the following diagram for a better understanding of our requirement.

Right Circular Rotation of an Array in C#:

In the following example, first we take the input integer array from the user. Then we perform right circular rotation using for loop.

using System;
namespace LogicalPrograms
{
    class Program
    {
        static void Main(string[] args)
        {
            int[] oneDimensionalArray = new int[6];
            Console.WriteLine("Enter the 1D Array Elements : ");
            for (int i = 0; i<oneDimensionalArray.Length; i++)
            {
                oneDimensionalArray[i] = int.Parse(Console.ReadLine());
            }
            
            int temp;
            for (int j = 0; j < oneDimensionalArray.Length - 1; j++)
            {
                temp = oneDimensionalArray[0];
                oneDimensionalArray[0] = oneDimensionalArray[j + 1];
                oneDimensionalArray[j + 1] = temp;
            }

            Console.WriteLine("Array Elements After Right Circular Rotation: ");
            foreach (int num in oneDimensionalArray)
            {
                Console.Write(num + " ");
            }
            
            Console.ReadKey();
        }
    }
}

In the next article, I am going to discuss how to find the angle between the hour and minute hands of a clock at any given time in C# with examples. I hope now you understood How to Perform Right Circular Rotation of an Array in C#.

int[] arr = Enumerable.Range(1, 6).ToArray();
//1,2,3,4,5,6
//6,1,2,3,4,5
int temp = arr[arr.Length – 1];
for(int i = arr.Length – 1; i>0; i–)
{
arr[i] = arr[i – 1];
}

arr[0] = temp;

foreach (int num in arr)
{
Console.WriteLine(num);
}
