Rotate Array Left

Write a C# Sharp program to rotate the elements of a given array of integers (length 4 ) in the left direction and return the array.

Test Data: 90, 30, 50, 40
Sample Output: Rotated array: 30 50 40 90
Test Data: -40, 10, -20, -10
Sample Output: Rotated array: 10 -20 -10 -40

Sample Solution:-

C# Sharp Code:

using System; // Importing the System namespace

namespace exercises // Defining a namespace called 'exercises'
{
    class Program // Defining a class named 'Program'
    {
        static void Main(string[] args) // The entry point of the program
        {
            // Calling the 'test' method with an integer array as an argument and assigning the result to the 'item' array
            int[] item = test(new[] { 10, 20, -30, -40 }); 

            // Outputting text to indicate the start of displaying the rotated array
            Console.Write("Rotated array: ");

            // Looping through each element of the 'item' array and displaying them
            foreach(var i in item)
            {
                Console.Write(i.ToString()+" "); // Displaying each element of the 'item' array separated by a space
            }
        }

        // Method to rotate an integer array by one position to the left
        public static int[] test(int[] a1)
        {
            // Returning a new array with elements rotated by one position to the left
            return new int[] { a1[1], a1[2], a1[3], a1[0] };
        } 
    }
}

Sample Output:

Rotated array: 20 -30 -40 10
