Hi You can use below code: public static void RotateRight( int [] input, int right) { for (var i = 0; i { RotateRightOne(input); } } public static void RotateRightOne( int [] input) { var last = input.Length - 1; for (var i = 0; i { input[i] ^= input[last]; input[last] ^= input[i]; input[i] ^= input[last]; } } Use: var arr = new [] {1, 2, 3, 4, 5, 6}; RotateRight(arr, 2);

Hey you mentation right circular rotation but you output showing left circular rotation. Any way, check the below code which is left circular rotation of an array. namespace MyConsoleApp { class Program { static void Main( string [] args) { int [] arr = new int [] { 1, 2, 3, 4, 5 }; int rotation = 2; Console.Write( "Original Array :" ); for ( int i = 0; i { Console.Write(arr[i] + " " ); } Console.WriteLine(); Console.Write( "Left Rotation of Array by " + rotation + ": " ); var newArray = LeftRotate(arr, rotation); for ( int i = 0; i { Console.Write(newArray[i] + " " ); } Console.ReadLine(); } public static int [] LeftRotate( int [] arr, int rotation) { int [] array = new int [arr.Length]; for ( int i = rotation; i { array[i - rotation] = arr[i]; } for ( int i = 0; i { array[(arr.Length + i) - rotation] = arr[i]; } return array; } } }
