Write a function that takes an integer and returns the smallest number that is greater than the given number which is a palendrome. For example, if the input was 111 the next palindromic number would be 121.
Write a function that takes an array of integers and returns that array rotated by N positions. For example, if N=2, given the input array [1, 2, 3, 4, 5, 6] the function should return [5, 6, 1, 2, 3, 4]
