rotate left array c# code example

Example 1: rotate array c#

List<int> iList = new List<int>(); 

    private void shift(int n)
    {
        for (int i = 0; i < n; i++)
        {
            iList.Add(iList[0]);
            iList.RemoveAt(0);
        }


    }

Example 2: rotate array c#

static int[] rotLeft(int[] a, int d) {

    Queue<int> queue = new Queue<int>(a);
    Stack<int> stack = new Stack<int>();

    while(d > 0)
    {
        stack.Push(queue.Dequeue());
        queue.Enqueue(stack.Pop());
        d--;            
    }

    return queue.ToArray();
}
