Left Rotation

  • ihateyou + 1 comment

    Is it possible to do the same in C# using only one array (as one array must hold the splitted values and other to place them accordingly) ?

      It is not the best solution but it requires only one array:

      static void Main(String[] args) {
        string[] read = Console.ReadLine().Split(' ');
        int n = int.Parse(read[0]);
        int d = int.Parse(read[1]);
        int[] array = new int[n];
        array = Array.ConvertAll(Console.ReadLine().Split(' '), Int32.Parse);
        
        for(int q=0;q<d;q++)
            for(int i=0;i<n-1;i++)
            {
                swap(array, i,i+1);
            }
        
        for(int y=0;y<n;y++)
            Console.Write(array[y] + " ");
        Console.WriteLine();
    }
    
    static void swap(int[] input, int indexA, int indexB)
    {
        int tmpA = input[indexA];
        int tmpB = input[indexB];
        input[indexA] = tmpB;
        input[indexB] = tmpA;
    }
