Array Elements left rotation in C# - undesirable output

Question

I am trying to create a C# function to left rotate array elements and store it in another array.

inputl = array to which rotated array has to be stored,

inputr = array to be rotated

shift = number of shifts.

Even though I pass the value of shift as any value the rotation takes place only once. Please help.

public static void LeftShift(int[] inputl,int[] inputr, int shift)
{
    for (int j = 0; j < shift; j++)
    {
            int temp = inputr[0];
            var last = inputr.Length - 1;
            for (int i = 0; i < last; i++)
            {
                inputl[i] = inputr[i+1];
            }
            inputl[last] = temp;
        }
    }
}

Answer 1

Here is my solution to your problem:

public static void shift(int[]al, int[]ar,int shift)
{
   shift=ar.Length-shift%ar.Length;
   for (int i = 0; i < ar.Length; i++)
       al[(i+shift)%al.Length]=ar[i];
}

If you remove the first line inside the shift method the output will be a right shift

Hope I could understand your problem and this is what you want

public static void shift(int[]al, int[]ar,int shift)
{
    int ind=0;
    for (int i = shift; i < ar.Length; i++)
    {
        al[ind] = ar[i];
        ind++;
    }

    for (int i = 0; i < shift; i++)
    {
        al[ind] = ar[i];
        ind++;
    }
}

Answer 3

I solved above program using below code.

public static List<int> rotateLeft(int d, List<int> arr) {
    int n = arr.Count;
    List<int> t = new List<int>();
    int h = d;

    for (int j = 0; j < n; j++)
    { 
        if ((j + d) % n == 0)
        {
            h = 0;
        }
       
        t.Add(arr[h]);
        h++;
    } 

    return t;
}
