Fastest algorithm for circle shift N sized array for M position

Question

What is the fastest algorithm for circle shifting array for M positions?
For example, [3 4 5 2 3 1 4] shift M = 2 positions should be [1 4 3 4 5 2 3

Answer 1

static int [] shift(int arr[], int index, int k, int rem)
{
    if(k <= 0 || arr == null || arr.length == 0 || rem == 0 || index >= arr.length)
    {
        return arr;
    }

    int temp = arr[index];

    arr = shift(arr, (index+k) % arr.length, k, rem - 1);

    arr[(index+k) % arr.length] = temp;

    return arr;
}
