# Python3 code for program to
# cyclically rotate an array by one
 
# Method for rotation
def rotate(arr, n):
    x = arr[n - 1]
     
    for i in range(n - 1, 0, -1):
        arr[i] = arr[i - 1];
         
    arr[0] = x;
 
 
# Driver function
arr= [1, 2, 3, 4, 5]
n = len(arr)
print ("Given array is")
for i in range(0, n):
    print (arr[i], end = ' ')
 
rotate(arr, n)
 
print ("\nRotated array is")
for i in range(0, n):
    print (arr[i], end = ' ')

#include <iostream>

{
    int i = 0, j = n-1; // i and j pointing to first and last element respectively
