# Python program to cyclically rotate an array by one

PythonProgrammingServer Side Programming

Given a user input array. Our task is to rotate cyclically means clockwise rotate the value.

## Example

Input: A=[1,2,3,4,5]
Output=[5,1,2,3,4]


## Algorithm

Step 1: input array element.
Step 2: Store the last element in a variable say x.
Step 3: Shift all elements one position ahead.
Step 4: Replace first element of array with x.


## Example Code

# Python program to cyclically rotate
#an array by one
# Method for rotation
def rotate(A, n):
x = A[n - 1]
for i in range(n - 1, 0, -1):
A[i] = A[i - 1];
A = x;
# Driver function
A=list()
n=int(input("Enter the size of the List ::"))
print("Enter the Element of  List ::")
for i in range(int(n)):
k=int(input(""))
A.append(k)
print ("The array is ::>")
for i in range(0, n):
print (A[i], end = ' ')
rotate(A, n)
print ("\nRotated array is")
for i in range(0, n):
print (A[i], end = ' ')


## Output

Enter the size of the  List ::5
Enter the Element of  List ::
8
7
90
67
56
The array is ::>
8 7 90 67 56
Rotated array is
56 8 7 90 67
