Check this

int[] array = new int[] { 1, 2, 3, 4, 5, 6, 7 };
int rotation = 3; //from which position you want to rotate
int[] newArray = new int[array.Length];
for (int i = rotation; i <= (array.Length - 1); i++)
{
    newArray[i - rotation] = array[i];
}
for (int i = 0; i < rotation; i++)
{
    newArray[(array.Length + i) - rotation] = array[i];
}
//To check rotation of array
for (int i = 0; i < newArray.Length; i++)
{
    Console.Write(newArray[i] + " ");
}

1. #Initialize array
2. arr = [1, 2, 3, 4, 5];
3. #n determine the number of times an array should be rotated
4. n = 3;
6. #Displays original array
7. print("Original array: ");
8. for i in range(0, len(arr)):
9. print(arr[i]),
11. #Rotate the given array by n times toward right
12. for i in range(0, n):
13. #Stores the last element of array
14. last = arr[len(arr)-1];
16. for j in range(len(arr)-1, -1, -1):
17. #Shift element of array by one
18. arr[j] = arr[j-1];
20. #Last element of the array will be added to the start of the array.
22. arr[0] = last;
24. print();
26. #Displays resulting array after rotation
27. print("Array after right rotation: ");
28. for i in range(0, len(arr)):
29. print(arr[i]),
