## Python program to right rotate the elements of an array n number of times:

In this post, we will learn how to *right rotate* or *right shift* an array for *n* number of times.
Right rotation or right *shift* means moving all elements of an array towards right. The rightmost element moves to the *start* and other elements are moved to right.

### Right rotation or Right shift of array numbers:

Letâ€™s take a look at the below image:

Here, we are rotating the array by *1* to the right. So, each elements are shifted by *1* to the right and the last element is moved to start.

Here, *n* is *1*.

To rotate the array for any value of *n*, we can perform the above step for *n* number of times.

So,

- Loop through the array from
*right*to*left*and shift all numbers by*1*position to its right. - Move the last element to the
*start*of the array.

### Python program:

Below is the complete python program:

```
def print_array(arr):
for i in range(0, len(arr)):
print(arr[i], end=' ')
print('\n')
given_arr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
print('Given Array :')
print_array(given_arr)
n = int(input('Enter the number of times for right rotation : '))
for i in range(0, n):
last_element = given_arr[-1]
for j in range(len(given_arr) - 1, -1, -1):
given_arr[j] = given_arr[j - 1]
given_arr[0] = last_element
print_array(given_arr)
```

Here,

*print_array*is used to print an*array*. This method takes an array and prints its value.- We are taking the
*rotation number*as input from the user and storing it in the variable*n*. - The outer loop is used to make
*n*number of rotation. On each iteration, it makes one rotation. - The inner loop makes the rotation by
*1*. It moves all elements by one to the*right*and then the last element is placed at the first position. This way, for*n*iteration, it moves all elements by*n*. - We are calling the
*print_array*before and after the rotation. Since it changes the original array, we are printing the same array two times.

### Sample output:

If you run this program, it will print output as like below:

```
Given Array :
1 2 3 4 5 6 7 8 9 10
Enter the number of times for right rotation : 3
8 9 10 1 2 3 4 5 6 7
Given Array :
1 2 3 4 5 6 7 8 9 10
Enter the number of times for right rotation : 1
10 1 2 3 4 5 6 7 8 9
```
